There is no one size fits all for exchanges. Every user has unique needs when buying and trading cryptocurrency.
Much the same as me.
I'm into KuCoin after I discovered that it has so various trading pairs available which you can truly go up with.
Just to give you some, they have
BTC-USDT,
XRP-BTC,
LTC-BTC,
BCH-BTC.
Likewise, they offer low fees. They furnish users with safe and reasonable cryptocurrency exchange transactions and services.
Obviously, you actually have the decision on your own. You can in any case pick another exchange, this just a part of giving my thoughts.
Just remember the saying that don't confide too much in them, and consistently make sure to be cautious and trade at your own risk. Also, as much as possible, keep the base amount conceivable.
