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.
