a low volume coin could easily manipulated but no with the high volume , if that what you mean then that's true , I couldn't agree more. It was a fraud that no one knows especially a newcomer.
For the first time they might would feel that's a crazy market , unbelievable and sucks experience. But you know it won't happened last forever , you'll get sweet profit and realize that the last time it was a pump and dump did intentionally not an ordinary market.
Actually, there are large groups that sometimes try to pump and dump a coin even with high volumes. Most of the members of these groups are huge buyers sometimes called as "Whale Pump" and earn huge profits. I am not exactly familiar with how they do things but I do know that they target coins such as EOS, POWR, GVT, etc
