Coinbase for me is a god tier exchange platform. It has been in the market for so long already. I started Bitcoin last 2016 and I remember that time Coinbase was famous already for being a great exchange as well as wallet. So yeah, Coinbase is highly recommended from my standpoint.
Coinbase is the first exchange I use when entering this market, and until now I still use it because it is very safe for me. However, high transaction fees are what many investors here do not like because there is no way for you to reduce transaction fees here. Besides, I am also using Binance because this exchange is where I choose to trade altcoins because a lot of good projects here help me to make good profits.
