I would like to add to this, namely to advise traders, especially newbies, to never trade using leverage, because we know that it is prone to potential market manipulation (fraud), and we know that it can be monitored at any time, so it will be dangerous and risky to be liquidated, therefore I suggest to remain an investor rather than a trader. Other than that, if you mean a trader who only does spot trades, then the best thing to do after that is to save it in a personal wallet rather than in an exchange wallet, and this is much safer, and we also know that there is a term "Not Your Keys Not Your Crypto" and especially for Bitcoin, as long as it is not in your personal wallet then it is not your Bitcoin.
