The only exchange platform in which when you sell short you don't get the cash from selling. Even 1 star is too much. Add the fees, non-existent customer service, insane lags, the fact that you can't change margin requirements for a position after liquidation (but if you close the position and then change - that's okay?), and pretty much everything else is terrible. Just terrible. Stay away at all cost, because any money you place in this, rest assured they will do everything in their power so you won't see it again.Nice addition: When logged in and holding a position close to liquidation, the website tends to crash before reaching liquidaiton price, so you can't buy or sell or do anything really to change the position. I am 150% sure they do this on purpose so that people who want to change their position before liquidation can't. Disgrace.Seriously, run away from this platform.
