am new in the game and am wondering which exchange will be best for a new trader, with respect to transaction fees and others
They are many exchange platform that are good for the traders actually, just check the top 30 exchange at the coinmarketcap.

Kucoin, Coinbene, Bitfinex, Lbank, Bittrex, Houbi, Okex, Binance, and many more.
