Some crypto exchanges have a built-in ‘hot wallet’ that allows investors to keep their Bitcoins in their exchange account, but this is not always recommended. Rather, invest in a good cryptocurrency wallet, preferably a ‘cold wallet.’ They may be expensive for some, ranging from $150 and up, but they are a good investment because they keep your crypto assets safe from cyber threats and other factors that can jeopardize your investments. The best cryptocurrency wallets on the market are the Ledger Nano X and the Trezor Model T.
