You never know how long they’re going to be able to prop up the scams. Additionally, many of the big exchanges, being unregulated, are alleged to (either directly, or through large players they’re associated with) manipulate the market and trade against customers. Front running, etc. Put up a large short position, and soon enough there will be a pump and dump to liquidate it. And if you do make money, have you noticed that these exchanges often go down for “maintenance” when big price movements are happening? There’s no guarantee you’ll be able to close out a position when you need to. The only way to win is not to play.
