I recommend you to save your funds in stable coins like USDT, USDC and BUSD. These coins are to safe and secure and also it's price will also stable. You can use exchange like Binance and wallet like Trust Wallet these are also most safe and secure for saving stable coins.
I'm afraid i wouldn't recommend a crypto enthusiast to save their funds in stable coins for the long term, it is not safe to do so; if you are prolly a trader who needs to move your funds into stable coins and then out to other crypto's for the purpose of your trade, then that might just be fine for you, but do not consider your funds secure or safe when you have them in stable coins, especially when it is for the long run, it is a centralized coin and quite a lot of things can go wrong with centralized coins, your funds could even be frozen and you would lose everything. Save your funds in decentralized cryptocurrencies, and store them in your own non-custodial wallet for maximum security.
