They make you buy at a higher price then the actual price, then sell lower then the actual price. Let's say you buy a coin that is .20 on every other exchange they will make you pay .23-.24 and as soon as you try to sell it a second after your purchase they will only give you .17-.18 for your coin. The price is still .20 on every exchange, nothing has changed. They make it so you can't get in and out unless there's a big move. And even when you do get out they will always give you lower than the actual price
