How to store Bitcoin: Wallets and security
To hold Bitcoin, you need to use a cryptocurrency wallet, which is mainly divided into:
Hot wallets (such as exchange wallets, MetaMask): Use online, convenient but high risk.
Cold wallets (such as Ledger, Trezor): Offline storage, the best security.
Hosted wallets (such as Coinbase): Managed by a third party, suitable for novices but not really "holding". The private key is the only certificate to control the asset. If it is lost, the BTC will be lost forever, so it is very important to back up the mnemonic.
