I saw a thread on BHW where someone asked members to join pump and Dump group. The actual thing is they are all scam. They will ask you to buy a particular coin at a particular time. And that coin's value will definitely multiply. But the fact is these whales/scammers buy that particular coin a minute prior before pumping. So, all those buying the coin after the pump will lose there money. Invest in long term coins. Also, I think BHW should ban such members who promote a pump and dump group.
