Besides, the spirit of crypto is peer to peer, why you still hang on to you third-party inbetween.
but if you are having at least thousand dollars and above I am sure you will make sure to keep them safer than in exchange.
so this will depend on how much and how long we are holding the coins.
there are traders i Know that keep their funds in exchange for at least day or week , but after their trading jobs , will withdraw the coins and transfer to their respective wallets .
been keeping must be safe and its keys hasnt been exposed to anybody which it should be the main priority.
