I study everything that pump and dump groups are doing. I like them.
When I see a coin they have pumped three times or more, it goes on my watch list... I buy into them, set my sell orders at previous pump levels... and move on... Some of them sit for a long time and do nothing. Many of them get pumped again, then I take my 200 to 300% profit, and re-invest in the known pump victims that are currently sleepers.
It's a long term plan, and it works. But it takes a long-term mindset. The great thing is, I don't sit and watch the charts all day. It only takes a half hour a day to monitor and set up... I establish my positions, then the pumpers do the work and I take profits... sometimes I don't realize that my sell orders have been hit and I took my profits until a day or two later.
Low stress altcoin profits - recently I started tweeting. @smokinaltcoins
Cheers and good luck.
