My opinion Yobit is Best exchange for beginner. yobit have many low satoshi coin and yobit not delist any coin. if you purchase any low trading coin not any fear to delist coin and your coin is safe for long time. other exchanges delist many low trading coins.
Seriously don't go with yobit. It has thousands of unsolved withdrawals and is filled with a lot of non existing and manipulative coins.
New generation exchanges like binance are the best choice to start with. You'll get interface quite easily.
