Certainly is. Gate.io from the main page of the site shows that it is aimed at beginner traders, since all experienced traders either already trade on it, or at least use it as an alternative platform. The floating commission for replenishing fiat and the inability to withdraw it is partly clouding the impression, but USDT perfectly solves all these issues. Lots of tools for passive income, the ability to copy the trades of experienced traders, as well as the ability to use more complex tools with growing experience in the matter, make Gate.io a great choice.
