If you are looking for stable coins there is no other than great and it is only USDT.  But I have to ask a question first, why you want stable coin/s?
Because for the fact that stable coin/s won't make you profitable than those volatile coins just like  Bitcoin, Ethereum, and the rest. If you are looking at this thing (profit), of course, I will invest these coins rather than to stick my money into no moving value coins.

Having this stable coin is only having the assurance that we can't lose our money and less risk but not good for investment, unless if you are just preserving your money in crypto.
