When buying bitcoin or another crypto asset for the first time, the first obstacle is not technical. It’s the bank transfer. Since October 2025, banks verify the match between the beneficiary indicated and the account holder of the recipient, including for transfers to crypto platforms. A poorly labeled transfer can be rejected without a clear explanation. Understanding this mechanism even before creating an account on a platform can prevent days of blockage.
Bank transfers to a crypto platform: the constraint that no one anticipates
The European regulation 2024/886 requires banks to verify the match on transfers. In practice, if the name associated with your bank account does not exactly match the name registered on the purchase platform, the transfer may be suspended or refused.
Before any cryptocurrency purchase, it is essential to check that your identity is strictly identical on both sides: same spelling, same common first name, same civility. A discrepancy of just one character is enough to block a transfer.
Some banks are more flexible than others regarding transfers to crypto platforms. Feedback on this point varies depending on the institutions and the amounts involved. For those who wish to access the crypto page of Mister Cash, the procedure details the verification steps to be followed on the banking side before initiating a transaction.
One practical tip: make an initial transfer of a small amount to validate the circuit. If this test passes, subsequent transfers will likely go through as well. If the transfer is rejected, contact your bank before trying again with a higher amount.
PSCA approval and MiCA regulation: check before buying
A simple PSAN registration is no longer sufficient to operate in France. Platforms must hold a European approval as a crypto asset service provider (PSCA), issued under the MiCA regulation, or benefit from the European passport of another member state.
This regulatory shift has direct consequences for the buying and selling of cryptocurrencies. Platforms that have not obtained this approval are expected to cease their activities and inform their clients about the fate of their assets. Those that continue without authorization risk being listed on the AMF’s blacklists.
What MiCA concretely changes for the buyer
The MiCA framework imposes specific obligations on approved providers:
- Segregation of assets: your crypto assets and funds must be separated from those of the platform, which limits risk in case of bankruptcy
- Complaint management procedure: the platform must handle your complaints within a formalized framework, with defined timelines
- Supervised custody of private keys: ESMA is conducting a coordinated control action on this subject until the first half of 2027
A point not to be overlooked: European approval does not automatically cover non-EU subsidiaries. When creating an account, it is essential to verify the legal name of the entity that actually holds the account and the assets. A well-known platform may route some clients to a non-European subsidiary, outside the MiCA scope.
Choosing a cryptocurrency purchase platform: operational criteria
A crypto platform should not be chosen based on its interface or the fees displayed on the homepage. The first filter is regulatory: does the platform have PSCA status or a valid European passport? Coinhouse, for example, is one of the historical French players that has followed this approval process.
The actual costs of a purchase in euros
The displayed trading fees represent only part of the cost. You must also add the spread (the difference between the buying and selling price at the same moment), withdrawal fees to an external wallet, and sometimes conversion fees if the platform operates in dollars.
The total cost of a purchase is measured by comparing the price paid to the market rate at the exact moment of the transaction. Some platforms offer limit orders that allow you to set a maximum purchase price, which reduces the impact of the spread.
Integrated wallet or external wallet
Leaving your cryptocurrencies on the platform after purchase is the simplest solution, but it requires trusting the provider’s custody infrastructure. Transferring your assets to a personal wallet (hardware wallet) offers total control over private keys, at the cost of increased responsibility for security.
For a modest investment, the integrated wallet of an approved PSCA offers a level of protection regulated by MiCA. For more significant amounts, custody on a hardware wallet remains the reference in terms of security.
Selling crypto assets and tax declaration in France
Selling cryptocurrencies generates a reporting obligation as soon as a capital gain is realized. Crypto asset disposals must be declared in your income tax return, even for small amounts.
Each disposal (sale for euros, exchange for another crypto asset, payment for goods or services) constitutes a taxable event. The calculation of the capital gain takes into account the total acquisition cost of the portfolio, not just the purchase price of the sold token.
- Each account held on a foreign platform must be declared via the dedicated form, under penalty of a fine
- Crypto tax software automates the calculation of capital gains based on the transaction history exported from the platform
- The flat tax applies to capital gains, but a progressive scale can be chosen if the tax profile justifies it
Complexity increases quickly as you multiply platforms and exchanges between crypto assets. Keeping a complete history of each transaction from the first purchase saves hours of reconstruction at the time of declaration.
The regulatory framework surrounding the buying and selling of cryptocurrencies has become significantly structured since the implementation of MiCA. For a buyer in France, the two reflexes to instill are verifying the PSCA status of the platform and maintaining a rigorous transaction log. The rest, from fees to wallet choice, is decided on a case-by-case basis depending on the amount invested and the frequency of operations.
