If you know erc20 it's on ED and it's very cheap but the volume trade is so high it even go to top 20 of the said exchanges. There's also EQUAL token that requires burning when you send transactions and it is accepted by most investors right now. Nousplatform also have a promising future, it's an exchange token and they have lots of big investors too. SGR or sugar exhange is also another option.
