1. The basics of buying cryptocurrencies

1.1 What is a cryptocurrency?

Cryptocurrencies are digital assets that run on a technology called blockchain. A blockchain is a decentralized, transparent and immutable digital ledger that records all transactions securely. Unlike traditional currencies (euros, dollars), cryptos are not issued by a central bank, but created through processes such as mining or proof-of-stake.

Each unit of cryptocurrency, such as Bitcoin orEthereum, is unique and can be used for payments, smart contracts or as a store of value.

1.2 Why buy cryptocurrencies?

Buying cryptos can meet several objectives:

Portfolio diversification : Cryptos allow you to add an uncorrelated asset to traditional markets.
Long-term investment : Some investors are betting on the continued rise of popular cryptocurrencies like Bitcoin.
Speculation : The high volatility of cryptocurrencies attracts traders looking to profit from rapid price fluctuations.
Payment method : Cryptocurrencies like USDT or Bitcoin can be used for fast and international transactions.

In 2025, interest in cryptocurrencies continues to be fueled by innovations such as decentralized finance (DeFi) and NFTs (Non-Fungible Tokens).

1.3 Understanding the risks associated with buying cryptocurrencies

Before buying your first cryptocurrencies, it is crucial to know the main associated risks:

Price volatility : Cryptocurrencies can lose or gain tens of percent in value in a matter of hours.
Security : Digital wallets and exchange platforms can be the target of cyberattacks.
Regulation : Governments, such as France, impose strict rules on capital gains and the holding of cryptocurrencies.
Scams : Fake projects or fraudulent platforms remain a major threat.

It is imperative to take these aspects into account to buy cryptocurrencies safely.

2. Steps to buy crypto safely

Now let’s move on to the practical part: how to buy cryptocurrencies in 2025 by following a step-by-step process.

2.1 Choosing a reliable platform

To buy crypto safely, the first step is to select a reliable exchange platform. With the growth of the crypto industry, the number of platforms available has exploded. Here are the key criteria to make an informed choice:

Regulation and compliance : Opt for a platform regulated in your country (like Coinbase or Binance for Europe). Regulation guarantees the security of your funds and the transparency of operations.
Transaction fees : Compare the fees applied for deposits, withdrawals and transactions. For example, Binance offers low fees, while Coinbase is known for higher fees but great ease of use.
Variety of cryptos available : Make sure the platform offers the cryptos you are interested in (Bitcoin, Ethereum, Altcoins, etc.).
Security : Check that the platform uses high standards of protection (two-factor authentication, cold storage, security audits).
User interface : Beginners will prefer intuitive platforms like eToro or Coinbase.

2.2 Creating an account on a platform

Once you have chosen the platform, the next step is to create your account. Here is a general tutorial to guide you:

Registration : Go to the website or application of the chosen platform and click on “Create an account”. Enter your email address and choose a secure password.
KYC (Know Your Customer) verification : Most platforms require you to verify your identity to comply with regulations. Prepare a copy of your ID or passport, as well as a recent proof of address.
Activating security : Activate two-factor authentication (2FA) to protect your account against possible intrusions.
Linking a bank account or credit card : Add a payment method to buy your first cryptocurrencies. Some platforms also accept PayPal or Apple Pay.

2.3 Making your first purchase

Choose cryptocurrency : Browse the list of available cryptocurrencies and select the one you are interested in (e.g. Bitcoin, Ethereum or another Altcoin).
Enter the amount : Indicate the amount you wish to invest in euros, dollars or other fiat currency. Most platforms allow you to buy a fraction of a cryptocurrency (for example 0.001 BTC).
Choose payment method : Select the payment method that you have linked to your account (bank card, transfer, etc.).
Confirm transaction : Check the details and confirm. The funds will then be credited to your platform wallet.

2.4 Securing your assets after purchase

Once your cryptocurrencies are purchased, the security of your assets becomes a priority. Platforms are not immune to cyberattacks. To protect your funds:

- Hot wallet : Digital wallet connected to the Internet, practical for regular transactions. Example: MetaMask.
- Cold wallet : Physical device (like Ledger or Trezor) offering maximum security through offline storage.

3.4 Decentralized platforms (DEX) and their regulation in different countries

With the rise in power of decentralized platforms (DEX), it is essential to understand not only how they work, but also the tax implications depending on the jurisdiction. DEXs (like Uniswap, PancakeSwap Or Sushiswap) are distinguished by their intermediary-free approach, allowing direct exchanges between users. However, their regulation and their tax treatment vary by country.

The specificities of DEXs in 2025

A DEX (Decentralized Exchange) is a cryptocurrency exchange platform operating on the blockchain, without a centralized intermediary. This means that users can exchange directly assets via smart contracts.

Benefits of DEXs:

Anonymity : Unlike centralized platforms, DEXs do not require identity verification (no KYC procedure).
Wide choice of cryptos : DEXs often offer rare or recently created cryptocurrencies.
Non-custodial : Users maintain control of their assets at all times.

Disadvantages:

Complexity for beginners : Using a DEX requires a basic understanding of wallets and smart contracts.
Risk of losses : Human errors (bad wallet addresses, high gas fees) or flaws in smart contracts can lead to significant losses.
Variable fees : Transaction fees (gas fees) can be high, especially on blockchains like Ethereum.

Taxes and regulations on DEXs in France, the EU and the USA

While DEXs offer more freedom, this does not exempt users from their tax obligations. Governments are beginning to tighten their monitoring of transactions carried out on these platforms.

France

In France, cryptocurrencies, including those traded on a DEX, are considered digital assets and are subject to specific taxation.

Taxation of capital gains :
- THE realized capital gains when selling cryptocurrencies are subject to Single Flat-Rate Withholding Tax (PFU) of 30% (including 12.8% income tax and 17.2% social security contributions).
- Exemption : Transactions whose total amount of transfers (sale or exchange of cryptos) in the year is less than €305 are not taxed.
Use of DEXs :
- Exchanges made on a DEX, even without conversion into fiat currency (euros, dollars), may be subject to tax declaration if a capital gain is noted.
- Mandatory declaration : All transactions must be mentioned in the annual income tax return, even if they are made via a decentralized platform.
Fines for non-declaration :
- Omission or tax evasion concerning cryptos can result in significant financial penalties.

European Union

The European Union is gradually harmonizing the rules concerning cryptocurrencies. In 2025, the Markets in Crypto-Assets (MiCA) regulation came into force, which has significant implications for DEX users.

MiCA regulation :
- MiCA requires increased transparency for centralized platforms, but DEXs are harder to monitor.
- Authorities are starting to monitor wallets and transactions on the blockchain using analytics tools (like Chainalysis).
General taxation :
- Capital gains on cryptocurrencies are taxed in most European countries, at varying rates (e.g., 25% in Germany, 19% in Spain).
- Some jurisdictions like Portugal remain attractive with reduced or zero taxation on crypto gains for individuals.

United States

The United States takes a strict approach to monitoring and taxing cryptocurrency transactions, including those made through a DEX.

IRS (Internal Revenue Service) :
- Any transaction in cryptocurrencies is considered a taxable transaction. This includes crypto-to-crypto trades made on a DEX.
- Taxpayers must report each transaction in their tax return (Form 8949), even if no dollar withdrawal has been made.
Tax rate :
- Short term : Gains made in less than one year are taxed as ordinary income (progressive rate ranging from 10% to 37%).
- Long term : Gains after one year of holding benefit from reduced rates (0%, 15%, or 20%, depending on income).
Declaration obligation :
- Centralized platforms like Coinbase provide tax statements (Form 1099), but this is not the case for DEXs. Users must therefore track their transactions themselves via tools like CoinTracker or Koinly.
- Users who fail to report their winnings may face fines and criminal prosecution.

Tips for staying compliant with crypto taxes

Use tax tracking tools :
- Software like Koinly, CoinTracker Or CryptoTaxCalculator help you track and report your transactions, even on DEXs.
Keep proof of all your transactions :
- Keep detailed records of purchases, sales, and transfers. This includes transactions made through a personal wallet.
Consult a tax advisor :
- If you are making significant gains or using complex tools like DEXs, a tax expert can guide you in minimizing your legal obligations.
