A good crypto exchange is an old exchange. The second is the ability to trade not only in long, but also in short. Accordingly, the number of exchanges is sharply reduced. And the third for me is the huge volatility. What it is, the better.
New exchange is also a new alternative for many investors because recently many good exchanges have a very nice interface and one of the new exchanges is very successful in security and that's why they have attracted many new investors to join. Joining the old exchange is not bad but we should choose a new exchange to be able to make better profits in this market.
