Well,it's depends on Thier community traders😉if the exchange has no volume how to be a good exchange anyway? Exchange are liable and listed some new tokens not only erc20,but I think all?trc20,Eos,etc.thats exchange will be a good,and most important thing is friendly recommended 😉😇😇😇
Volumes can be manipulated by big holders in any new exchange. And there have been a lot of these new exchanges popping up. Some seem legitimate and some are obviously shady. A lot of options for traders but can be confusing if you're subscribed to a lot of them already.
