A cryptocurrency airdrop is a significant event in the DeFi sphere that has attracted the attention of millions of users. For instance, in September 2020, thousands of people found free tokens worth hundreds of dollars in their crypto wallets after Uniswap decided to reward everyone who used its platform by distributing 400 UNI tokens to each corresponding wallet. At the time of the event, this was worth about $1200, while at the peak price of UNI, it exceeded $17,000.
Fundamentally, a crypto airdrop is a process where a blockchain project distributes tokens for free directly to wallet addresses. This can be compared to an advertising campaign where, instead of a coupon, the user receives actual cryptocurrencies. The term originates from a military term denoting the dropping of supplies from the air, and in cryptography, tokens are 'dropped' into wallets, often without any additional action required from the recipient, other than holding a specific coin or using a particular protocol to verify price forecasts.
From a technical standpoint, an airdrop is a smart contract transaction that moves tokens from the project's treasury to a list of qualified addresses. The rules are set by the project itself, and the blockchain automatically executes these instructions without requiring manual approval from the user.
Projects conduct airdrops not out of charity, but for strategic reasons. Firstly, it accelerates the formation of a user base. New protocols need liquidity and active users from day one, and an airdrop instantly creates a community interested in the platform's success. Secondly, it promotes decentralized governance. Many DeFi protocols aim to transfer authority to the community, and distributing governance tokens, such as UNI or ARB, among real users is a legitimate way to achieve this goal. Finally, projects reward early adopters who took risks by using an unproven protocol before it became popular.
The operation process of airdrops is relatively simple and involves several stages. First, the project takes a 'snapshot' of the blockchain at a specific block height, recording all addresses that meet the criteria. Then, the team conducts a compliance check, determining whether the address held a minimum amount of a certain coin, interacted with the protocol before a set date, or completed assigned tasks. After this, tokens are sent to all qualified addresses via a smart contract, which can happen all at once or in batches. Some airdrops require actively claiming tokens through the project's website before the deadline, otherwise, they may remain unclaimed forever.
There are several airdrop models. Standard airdrops are the simplest: the project distributes free tokens to a wide range of addresses, usually holders of a certain coin above a minimum threshold, without requiring any action from the user. For example, Stellar (XLM) conducted one of the largest standard airdrops, distributing over 2 billion XLM to Bitcoin holders to raise awareness. Bonus airdrops require task completion: users must follow on Twitter/X, join Telegram groups, post content, or refer friends. These airdrops are often used by new projects as a form of marketing. Holding and exclusive airdrops reward simply for holding a specific token; for instance, the ApeCoin airdrop was exclusive to holders of Bored Ape Yacht Club NFTs.
A retroactive airdrop is a reward for actions taken in the past. It is granted to users who used the platform before the official announcement of the distribution. Uniswap used this approach in 2020, distributing 400 UNI to every wallet that used the platform before September 1, 2020. This allows the project to trace the blockchain history and identify interacting wallets.
To increase the chances of receiving an airdrop, it is necessary to position oneself correctly before the announcement. Experienced participants use early-stage protocols that have attracted venture funding but have not yet launched a token. They are advised to interact with the network, swap tokens, and provide liquidity to build a history of activity on the blockchain. It is important to make transactions regularly over several weeks and months, and also use cross-chain bridges, as this signals real activity. Furthermore, participating in testnets can place the user in a small group of potential recipients.
Legitimate airdrops are safe, whereas fake ones are an effective method of theft. Signs of fraud include requests to connect a wallet to an unknown website to 'receive' tokens, receiving an airdrop in private messages on social media, demanding that cryptocurrency be sent first to 'unlock,' or requesting a seed phrase. To protect yourself, you should only interact through the project's official, verified social accounts and use a separate 'airdrop wallet' with a small balance.
Trading cryptocurrency using leverage has become very popular in recent years. However, this concept can seem complex for beginners. This guide aims to explain as simply as possible what leverage is, how it functions in the crypto sphere, and when it should be used and when it should be avoided.
Essentially, leverage in crypto trading is the practice of using borrowed funds to increase your buying or selling power. This can be viewed as a temporary loan taken from an exchange. Thanks to these borrowed funds, you can execute trades with a much larger asset volume than what you actually own.
In standard spot crypto trading, if you have $1000, you buy Bitcoin worth $1000. If the price of Bitcoin increases by 10%, you earn $100. When using crypto leverage, you can use those same $1000 as collateral to open a $10,000 position (10x leverage). With such a larger trade size, if the price of Bitcoin rises by the same 10%, your profit will be $1000. Nevertheless, higher profit potential comes with increased risks.
To understand how leverage works in crypto, you need to grasp the lending model from the exchange to the user. Exchanges that provide funds for leveraged trading are commercial entities, so they do not do it for free. They require collateral, called Margin, to ensure they do not incur losses if your trade fails.
Margin is essentially the crypto assets you deposit as collateral to open a large position. There are two types of margin, and it is important to know both. The first is Initial Margin, which represents the minimum amount of equity required to open a leveraged position. The second type is Maintenance Margin, which is the minimum capital that must remain in your account to keep the position open. If your account balance drops below this threshold due to market losses, you risk a margin call.
Leverage is expressed as a coefficient, which is the multiplicative effect. It shows how many times your initial capital is multiplied. When you see 5x, it means you are trading $5 for every dollar. At 10x, you are trading an amount 10 times greater than your starting amount. 100x leverage is usually limited to Bitcoin trading, where a $100 deposit can open a $10,000 position. A very high multiplier has a dual effect: while huge profits can be made, the risks are also great.
100x leverage implies that any move against you of 1% will lead to the loss of 100% of your collateral. Furthermore, only some leading platforms for high-leverage crypto margin trading, such as MEXC, offer such a multiplier.
Leveraged cryptocurrency trading is available not only in a bull market; it can also be used in a bear market. This is where long and short positions come into play. In a long position (Longing), you borrow funds to buy an asset hoping its price will rise, and then sell it back, repay the loan, and receive the difference. In a short position (Shorting), you take an asset, such as BTC, and sell it on the spot market. If the price falls, you repurchase it at a lower price, deliver the BTC to the lender, and keep the profit.
A key aspect of leveraged trading is risk management in different modes. Most platforms offer two modes. In Isolated Margin mode, the risk is limited to a specific trade; if that trade fails, you only lose the percentage allocated to that position. In Cross Margin mode, your entire account balance is used as collateral. While this prevents liquidation during short-term price drops, a more significant decline can automatically empty your wallet.
There are several ways to approach crypto leverage trading. Depending on the chosen exchange, you can trade various instruments. Crypto margin trading is the most common form, where you borrow funds directly from the exchange or other users to buy more spot crypto. This is often used for short-term speculation and involves daily interest payments on the borrowed amount.
Cryptocurrency futures and perpetual contracts are used to buy or sell an asset at a specific price at a given future time. In the crypto sphere, perpetual swaps offer additional advantages because they have no expiration date and are tied to the true price of Bitcoin or Ethereum via a funding rate. Options give you the right (but not the obligation) to buy or sell at a specific price. Although this is more typical of traditional finance, options are also available in the crypto sphere. CFDs (Contracts for Difference) are simply betting on price changes, where you never own the underlying currency.
Liquidation means the end of the game in leveraged cryptocurrency trading. Since exchanges are businesses, they cannot assume all the trader's risks. When an exchange detects that your trade is losing money and has reached the depletion point of the Initial Margin, it automatically closes your position. This closure is called liquidation. Upon receiving a liquidation notification, you understand that you have lost 100% of the collateral you allocated to that trade. Exchanges do this to protect their own funds from losses on your position and to prevent you from having a negative balance.
If you do not want to risk the risks associated with leveraged trading, you can engage in spot trading. While using leverage, you borrow to trade large volumes, whereas in spot trading, you directly buy or sell the crypto asset at current prices. The main differences between these methods are as follows: beginners are recommended to start with spot trading, while leverage is suitable for experienced traders willing to accept the associated risks.
After understanding the principle of leverage, let's look at how to trade it on an exchange, such as Binance. You need to choose a reliable exchange with high liquidity to avoid scam candles that cause liquidations. Then, you need to deposit collateral (USDT or BTC) into the Futures or Margin account. Next, select the margin mode and the desired leverage level, with beginners advised to start with small values, such as 2x or 3x, avoiding promises of 100x. It is crucial to set a stop-loss to automatically close the trade upon reaching an acceptable loss. You must also constantly monitor the trade and adjust the stop-loss to a profit zone if the result is positive. It should be noted that maintaining an open trade may require paying a fee every 8 hours.
Advantages include the ability to earn huge profits from small price fluctuations (1-2%) and using a small capital to access large trade sizes. Additionally, BTC holders can use leverage for short selling to hedge their portfolio during a market crash. Disadvantages include the high volatility of crypto leverage, where one small market move can zero out the balance. Also, the stressful state of watching a leveraged position and the need to master complex concepts such as funding rates, mark prices, and liquidation prices require a steep learning curve.
Beginner traders are strongly advised to approach leveraged trading with extreme caution. The process should only begin when you have a proven trading strategy and a disciplined approach to risk management. Crypto leverage is a tool for professional growth, not a get-rich-quick scheme. If you are just starting, stick to spot trading until you understand market cycles. When moving to leverage, start with 2x and always use a stop-loss to minimize risks.
Decentralized Finance (DeFi) fundamentally differs from the traditional financial system because it lacks intermediaries. Instead, it utilizes only the user, their cryptocurrency, and software code running on a blockchain.
The industry is demonstrating significant growth. As of the end of 2024, the total value locked in the DeFi sector reached $133.6 billion, which is 2.5 times higher than the $50 billion recorded in December 2023. By the end of 2025, this amount increased to $172 billion.
DeFi stands for Decentralized Finance. It represents a collection of financial services, including lending, trading, savings, and earning income, that operate on public blockchains, bypassing banks or corporations. The significance of DeFi goes beyond simply eliminating banks; it means that anyone with a crypto wallet and internet access can utilize financial services that were previously restricted by geography, credit score, or income.
Users can borrow against their crypto assets, earn yield, or make price predictions for coins. The concept of DeFi began gaining momentum around 2018 when Ethereum developers started creating open financial tools on the blockchain.
Most people are accustomed to traditional financial institutions where banks hold funds, set interest rates, and determine loan recipients. The DeFi model is completely opposite to this. In traditional banking, a central authority controls the funds, whereas in DeFi, all processes are automated using smart contracts—self-executing code. Banks operate during business hours, while DeFi functions 24/7, 365 days a year. The traditional system requires identity verification and approval, whereas DeFi only requires a crypto wallet. Furthermore, DeFi protocols are open source and can be audited by anyone online, unlike internal bank rules.
The issue of access is also important: according to World Bank data, about 1.4 billion adults worldwide remain unbanked. For DeFi, this is irrelevant because the system does not consider the user's credit history or country of residence; having a phone and a wallet is sufficient. Nevertheless, DeFi does not provide consumer protection, fraud recovery, or deposit insurance offered by banks. This underscores the critical importance of understanding DeFi's operating principles before investing funds.
Smart contracts are the driving force behind the entire system. They are computer programs deployed on the blockchain that execute actions automatically when specific conditions are met. They can be compared to a vending machine: you put money in, and the machine dispenses a product without human intervention. These programs ensure fairness and transparency because all actions are visible to everyone.
Users interact with these contracts through decentralized applications, or dApps. They look like regular websites or mobile apps, but instead of connecting to a company's server, they connect directly to the blockchain via a personal wallet. For example, when participating in yield farming in DeFi, the user does not transfer personal data or register as they would at a bank.
Ethereum is the leading blockchain in the DeFi sector, holding over 68% of the total value locked. However, other networks such as Solana, BNB Chain, and Avalanche also capture market share, sometimes offering faster transactions or lower fees than the Ethereum network. On Ethereum itself, smart contract interactions account for nearly 62% of all daily transactions, with DeFi protocols providing about 25% of the total network transaction volume. This entire process is executed automatically by code, without human intervention.
Decentralized Exchanges (DEXs) allow users to trade cryptocurrencies directly from their wallets, eliminating the need for account registration, KYC verification, or withdrawal limits imposed by corporations. Instead of a traditional order book, DEXs use liquidity pools. Users contribute pairs of coins to a common pool, and an Automated Market Maker (AMM) algorithm sets prices based on supply and demand. Uniswap is the largest DEX by volume, and Curve is a preferred choice for many investors when exchanging stablecoins.
DeFi lending works similarly to a bank loan, but the process is less cumbersome. A user deposits crypto assets into a protocol like Aave or Compound, and other users can borrow against those assets. The smart contract automatically manages interest rates, collateral requirements, and repayment. Borrowers usually have to provide more crypto assets than they borrow, which protects lenders in case of sharp price drops. In return, lenders receive interest paid directly to their wallets, often at rates higher than those offered by banks.
Staking in DeFi involves locking up coins in a protocol to support its operation and earn rewards. In Proof-of-Stake blockchains, such as Ethereum, stakers help validate transactions and receive a portion of network fees. Protocols like Lido have made this accessible without deep technical knowledge: users deposit ETH and receive stETH—a liquid token representing their stake—while continuing to earn rewards. Lido currently holds about $27.5 billion in TVL, making it the largest individual DeFi protocol by this metric.
Yield farming goes further: traders move their cryptocurrencies between different platforms to maximize profit. Typically, they deposit capital into liquidity pools, receiving special reward tokens in return, and then stake these new assets in other dApps to maximize returns. Although potential yields can be high, risks exist, including impermanent loss, the possibility of scams, and general risks associated with the farmer's activity.
A DeFi wallet is a tool for accessing the entire crypto market. Unlike wallets on centralized exchanges, where the exchange technically controls the coins, a DeFi wallet gives full direct control to the user. MetaMask is the most common option for Ethereum and EVM-compatible networks, while Trust Wallet supports multiple blockchains in one application, popular among Solana users—Phantom.
DeFi has brought numerous benefits to millions of people by providing control unavailable in traditional banks and creating new ways to earn cryptocurrency. As of August 2024, the number of DeFi users exceeded 83 million. Earning potential through yield farming, liquidity provision, and staking can surpass the returns from savings accounts or government bonds. Some individuals have become millionaires by entering the DeFi sector and may even receive free funds through airdrops or participation in presales.
However, serious risks remain: smart contract bugs, exit scams, and extreme market volatility can lead to instant loss of funds. Even experienced users have lost money due to poorly audited protocols or sudden price drops causing liquidations. Moreover, most jurisdictions still define the legal and tax status of DeFi crypto activities, which may change in the future.
DeFi is a financial system that runs on code, not institutions, accessible to anyone with a wallet and internet, and operates without central authority permission. Although regulation has not yet kept pace with development, and the user experience requires learning, the risk of smart contracts remains real. Nevertheless, the growth of this sphere cannot be ignored.
In the rapidly growing cryptocurrency industry, the Lemon project aims to simplify blockchain usage while providing benefits to its early supporters. Lemon has established itself as a significant name in the crypto community, combining innovation, community engagement, and real-world practical application.
The Lemon crypto project, also known as Lemon Cash or via the domain Lemon me, is a crypto-fintech application. It is designed to help users easily manage, buy, and sell cryptocurrencies. Founded by Marcelo Cavazzoli in 2019, this service aims to simplify the use of digital currencies in daily transactions, blending traditional banking-like functions with modern crypto tools.
The application offers a contactless VISA card for international payments, allowing transactions and purchases without needing to enter a PIN. A special feature is the ability to receive Bitcoin cashback on every purchase made with this card. Users can also deposit or withdraw over 30 different cryptocurrencies across 16 blockchains, maintaining full control over their digital finances.
Furthermore, the Lemon Earn feature allows users to invest their assets in Decentralized Finance (DeFi) projects and earn competitive interest rates on digital assets. The company places great emphasis on transparency, regularly publishing financial reports to demonstrate responsible fund management. According to the latest data, the platform serves over 4.5 million users in Latin America, including Argentina and Peru, and has issued over one million VISA cards.
Getting started with the Lemon project is quite simple: after downloading the app, the user creates an account and completes the KYC procedure, which is standard practice for crypto-fintech applications. After completing KYC, users can top up accounts with fiat money, such as Argentine pesos, or cryptocurrency.
The application provides seamless functionality for buying, selling, or exchanging various cryptocurrencies, including BTC, ETH, and stablecoins. Lemon supports various blockchain networks for both deposits and withdrawals. Through Lemon Earn, users can convert unused cryptocurrencies into DeFi protocols to generate daily or periodic profit. When selecting a cryptocurrency and a DeFi protocol, income is generated through investment yield. Since there are no fixed lock-up periods, users can withdraw their cryptocurrency or move it to other DeFi protocols at any time. Supported cryptocurrencies include USDT, USDC, DAI, ETH, AVAX, and POL.
The Lemon card linked to the user's account should not be forgotten. When using this card, users earn Bitcoin cashback (approximately 2%) on every transaction. This prepaid card operates internationally and supports contactless payments. Additionally, the app supports payment via 'QR' systems, especially in Argentina, allowing crypto cashback based on QR transactions.
Users can pay for services and bills directly within the app using either cryptocurrency or fiat currency. Lemon emphasizes transparency by providing a public Proof of Reserves and Solvency Protocol, allowing users to verify their funds. Considering the risks associated with cryptocurrencies, the company stresses the importance of transparency to gain trust. The platform sets limits on crypto transactions and card spending, but users can request limit increases by providing additional documentation. In many jurisdictions, Lemon is registered as a virtual asset service provider and complies with local financial regulations.
Marcelo Cavazzoli serves as Founder and CEO. He founded Lemon in 2019 and possesses over 25 years of experience in the financial sector, holding positions as CFO at HSM/WOBI and Wolox. Marcelo showed an interest in programming from an early age and previously launched several startups.
Maximiliano Raimondi holds the position of Chief Financial Officer. With over 25 years of financial experience, he specializes in bridging traditional finance with the world of cryptocurrencies.
Federico Biscupovich, Chief Operating Officer, is a technology engineer from the University of Buenos Aires and has been with the company since its early stages, overseeing processes and facilitating expansion.
Currently, a native Lemon token does not exist, but the platform supports trading well-known tokens such as BTC, ETH, and stablecoins.
Lemon has raised a total of $66 million. In the initial stage, the company secured seed funding of approximately $1.1 million. This was followed by a Series A funding round of about $16.3 million, which was subsequently extended. Furthermore, another Series A Extension of approximately $27.8 million was added.
On October 8, 2025, the company completed a Series B funding round, raising about $20 million from F-Prime, ParaFi, DRW Venture Capital, Endeavor Catalyst, Van Eck, and other US investors. This round increased the total amount raised to $66 million, meaning approximately $46 million had been raised in previous stages. With this new capital, Lemon is preparing to expand operations into new territories such as Colombia, Mexico, Brazil, and Chile, aiming to reach 10 million users within the next year.
Currently, Lemon processes over 7 transactions per second. In 2025, a volume of $9.3 billion is projected to be processed, in addition to $160 million in user assets.
In 2021, the company achieved significant milestones by launching the Lemon Card—a prepaid VISA card allowing users to spend cryptocurrency anywhere and receive Bitcoin cashback on every purchase. This step integrated digital assets into daily payments and introduced crypto-banking via prepaid cards in Latin America. In the same year, the Proof of Reserves system was introduced, giving clients the ability to view their balances and crypto assets in real-time directly within the app.
By 2022, the user base exceeded one million. The team also implemented Lemon Earn—a DeFi yield product that allows clients to earn interest on their crypto assets. Despite the global market downturn, the platform maintained innovation and flexibility, adapting to the changing conditions of the crypto space.
In 2023, the brand continued its expansion across Latin America, entering the Peruvian market and preparing for launches in Colombia, Mexico, Brazil, and Chile. Education and transparency remained priorities, evidenced by the publication of reports and educational materials on cryptocurrency adoption in the region.
A year later, the company reached 4.5 million users and issued over one million Lemon cards. The 'Crypto Industry State of 2024' report was also published, analyzing trends in DeFi usage and adoption across different regions. To strengthen trust, Proof of Solvency in real-time was implemented, allowing anyone to check its financial status at any time.
In 2025, growth accelerated thanks to the $20 million Series B funding round led by F-Prime and ParaFi, bringing the total investment to $66 million. The new capital supports the ambitious goal of reaching 10 million users within a year and expanding into other Latin American markets. According to official statements, by the end of 2025, the platform expects to process over $9.3 billion in transaction volume and hold more than $160 million in user assets. The company has also begun holding Bitcoin in its corporate treasury, aligning its long-term strategy with the broader decentralized finance ecosystem.
Currently, the Lemon airdrop is not taking place. There is also no confirmed date for the Lemon TGE.
Lemon has established itself as one of the leading crypto-fintech companies operating in Latin America. Founded by Marcelo Cavazzoli in 2019, the platform connects traditional finance with Web3, enabling millions of users in Argentina, Peru, and other countries to buy, store, and use cryptocurrency in their daily lives.
Thanks to offerings like Lemon Card (VISA card with Bitcoin cashback), Lemon Earn (DeFi yield integration), and Proof of Reserves (ensuring real-time solvency verification), Lemon positions itself as a transparent and user-centric crypto ecosystem. Lemon goes beyond being just a wallet or an exchange; it is a full-fledged financial hub where users can earn interest, pay bills, make international purchases, and easily manage assets in both fiat and crypto form.
Recent investments of $20 million in the Series B (2025) and a user base exceeding 4.5 million underscore Lemon's reliability and prospects for further growth, especially as its presence expands throughout Latin America. Among the platform's advantages are a user-friendly interface, an integrated financial ecosystem, strong regional focus, transparency and trust, as well as regulatory compliance and KYC. Disadvantages include limited global availability, the absence of its own token, and the fact that the Lemon wallet is not fully decentralized, as well as dependence on crypto market conditions.
