on the off chance that a trade were controlling costs then they wouldn't require your bitcoins to do it, they will do it with or without them. in the event that you don't trust me investigate Yobit. they are controlling cost of no less than several altcoins consistently. they needn't bother with anybody to have any stores there, it is an incorporated shut database which they can enter anything into. for instance you can see they are pushing the volume up counterfeit, they put heaps of purchase arranges in the history again phony and push the cost up by avoiding the offer requests and phony pumps. all phony and without spending anything.
