Pump and dump schemes are very detrimental to cryptocurencies in general.In fact the SEC have a ransom for people who expose such schemes for prosecution.The market manipulation by such schemes exposes innocent and unsuspecting investors to too much risk and detrimental losses.It should be something that should be condemned.
Exactly right. They scam people knowing that the members of that group will gain profit out of that but instead they call the pump when they have already bought the coin and tell the others to buy without knowing that its already been set up.
