In terms of trading my trades, I prefer Kucoin and Coinbase. However For wallets, I prefer Trust Wallet and Metamask. Kucoin has good fees if you trade a lot and both Kucoin and Coinbase have very good reputations. These are also two things I recommend when bringing in new people in the Crypto Community..
Unlike me when new people ask about the best platform for trading, because I always recommend the Binance exchange as well as the FTX exchange for them, because the Binance Exchange also has very low fees and even Free if you trade on BUSD.
Binance would probably have a lot of recommendations here if OP would make a poll.
Personally, I would also suggest Binance as they are a growing platform, seeing BNB to be in the top 3 of the altcoins market, that is a good statement that Binance will not go anywhere, it's development will be going up and so the price because more traders will choose Binance over other exchanges.
