Ryan pumper , Bob surplus, and all they have a good P& D Group
But im not want to join him, i think we can learn with read grafick and learn from more source
also we can watching how P & D group action, emm when accumulation and when time to sell
we can see it but some people still join to P & D group give some BTC to him and pump will be do with him use your money
(sorry my english not bad ?

)
it is easier said than done. but i totally agree with what you said.
i think mostly people join these groups because they don't have any prior knowledge about trading at all. then they start trading a little and just lose money in almost every trade they make. then they look for a solution, and that is where they encounter these groups with nice profits (numbers they show) and logically they want to try them
