Recently we were surprise by ExtStock exchange with many altcoin pumps. I think this is fake because it is not natural in the pump so that this pump makes a lot of attention, especially beginners who yesterday joined the XT airdrop from this exchange themselves.
Just an fake pump to attract some traders and its not a new thing. Including this one there is many more scam supporting exchanges who don't care about fake team, plagiarism. All their intention is just to get the listing fee and this kinda fake volume is their another trap for new traders. Experienced user will never run after fake volume and sudden pump because they know they will get nothing but some useless tokens after placing their buy orders.
