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.
I'm not too sure if a good exchanger is an old exchange.
Isn't there a new exchanger like Binance, Idax, IDEX and so on, is there an old exchanger?
the good or bad of an exchanger cannot be determined by the old or new exchanger,
but security, volume, convenience and other exchanger supporters that make an exchanger good.
