It really is what you are comfortable with. I personally feel safer with Coinbase as it’s one of the top
Crypto Exchanges out there, but ultimately it’s all about your own comfort levels. If you go for people’s choice, it could be very likely that you might not be comfortable at all. So this is where go with what comforts you, as eventually it’s about that only. I am doing that only because I know how much this means for my performance.
If you are trading with limited number of coins, well, coinbased is a good choice too, but we know most of the traders likes an exchange where there's a lot of coins listed with great volume, and the exchange that I know that provides that is no other than Binance.
This exchange also continues to list coins through their IEO, so there will be a new one coming and those old might be delisted.
Investors will choose to trade on exchange that is hype and Binance is hype, especially the IEO now, and even the new listing of coins, it brings hype that if you are good and you know how to do it with timing, you will surely enjoy an instant profit.
