For me any open source decentralised exchange is good to go with but to be specific you can go for dex like bisq.
Bisq is one of the famous open source decentralised exchange that anyone can use the only difference in this decentralised exchanges is that exchanges rates are little bit lower than in centralised exchanges and I thinks it's a price for your privacy for those of us who value privacy then it's absolutely the one of the best but perhaps one can still make research on other Dex exchanges to use.
To break it you OP alot of people here in the local board has left binance already for centralised exchanges like kucoin, but, Houbi etc. Since the beginning of the issues with binance in Nigerians has moved on already.
And make nobody keep any coin in my exchange except dex.
perhaps I will say there is no exception for storing coins in an exchange whether of the centralised or decentralised. It's really no good to keep ones assets on an online exchange.
It's more adviced to used wallets to store your assets (coins) especially non custodian wallets and open source wallets like Electrum for bitcoin and unstoppable wallets, Metamask wallets for both altcoins etc.
But if you want to hold little amount you can use any of the quick access wallets online in other to carry out transactions but if you don't care about privacy you could use exchanges for your day to day use of bitcoin and other coins.
