Bitstack is licensed as a Crypto-Asset Service Provider (CASP) in accordance with the European MiCA regulation. Our activity is supervised by the Autorité des Marchés Financiers (AMF) and the ACPR – Banque de France, which ensure the compliance and security of our third-party crypto-asset custody service.
We have put in place several measures to ensure the security of your account, your data, and your money. We have eliminated all single points of failure, such as private key management as it is never accessible from a single device at any given time, and we have also implemented specific approval policies for each transaction to avoid any possibility of computer compromise.

If you want to secure your bitcoins yourself, you can withdraw them and send them to an external BTC address at any time. Here is an article to know how to send some Bitcoins from a wallet to another one.
