Huobi mini pumper = same guy who´s tryin to sell 500-600BTC at the same time on Stamp?
one does not sell by buying.
Everyone is followin huobi, 50 BTC get bought over there, he lures people in to buy into his 500-600BTC sell order, makes sense?
Happened with Gox before.(Pump on Gox - sell on Stamp)
