You can move your Bitcoins to a private wallet as mentioned by several other members. You can also move your funds to exchanges such as KuCoin, Bybit, MEXC or others.
But it's best to keep your Bitcoins in a private wallet and only send them to an exchange if you want to trade them.
You can buy a hardware wallet to store Bitcoin and other altcoins. It will be safer and more comfortable for you because you won't worry about anything.
Agreed on all of your suggestions for using a private wallet and for the exchange suggestions except MEXC as a Binance alternative. On Kucoin and Bybit, we can speculate that both of them have a chance to be the next biggest exchange in the cryptospace, however, MEXC be careful, I reckon. I do not have any proof that they selectively scam people but I would not trust this exchange over Kucoin and Bybit.
