am new in the game and am wondering which exchange will be best for a new trader, with respect to transaction fees and others
I think it's Binance. It is the No. 1 crypto market and has hundreds of millions of dollars daily traded in Binance. You won't have to worry about the quality of the altcoins listed in Binance because of the altcoins that have been rigorously censored by Binance's team. The transaction fee is not too high and security is absolutely good. You can rest assured when dealing there.
