There are members here that frequented new exchanges and they have the habit of giving honest reviews, but so far I haven't heard anything very positive about an upcoming exchanges except for shills account.
A lot of new exchanges is coming into crypto market.
Now a days it is very important that which exchange is good for trading which is not.
So it is advise able to search necessary information before doing trading on any new exchange .
I agree that we really need to take a deep look at new exchanges popping around, they can offer something different in the beginning but it doesn't mean they won't pull a exit scam, so we have to take a look specially liquidity and trading volumes so that we won't get deceived in the end.
