I've tried several pump groups and I would like to share with you one that I have best experience with.

PROS
Pumps really work for all! Even with the basic account you'll have enough time to make profit - the peak of the price is usually 10 minutes after the announcement for all!
Unlike other pump groups, they provide professional instructions - there is no useless 'everybody will get lambo' hype talk, but only those information you need to make XXX% profit.
They are monitoring the market and if the market is highly volatile or disturbed pumps are postponed.
CONS
There is not enough pumps Smiley! Usually they publish pumps approximately two times a month.
