Though all ponzi schemes are scam on the long run and would eventually crash and fold when the GH gets more than the PH without newer PHs. Now there are some with the intention of redistributing wealth around, others are just out to mop up the money from everyone into one person's pocket and zoom, he is gone. Here are few tips you should follow not to get scammed so easily, I have lost a substantial amount of money and have decided that you should not suffer same fate:

1. Very high interest rates within a short time.
When sites tell you to invest your bitcoins with 100% interest in a week, its a scam. No business can make 100% continuously every week. Making 100% or more in a genuine business investment is possible, but not continuous.

2. Payment to ADMIN
Even after registering at any site, once you are mandated or paired to pay to Admin, please run, run very fast. It is a scam and you would most likely lose your money. Admin means that the money is in an account that cannot yield you any profit. Some sites like Trevizaglobal, MAC and Helping Revolution used this model to scam unsuspecting investors of millions.

3. Central Account Payment
Don't make payments into any ponzi scheme if you find out its to a central account. Why MMM Nigeria survived long was because payments were not centralized, either you are paired to someone who can also communicate to or don't pay. If you follow my advice you would not encounter loss.

thank you.....but these didnt work for MMM

Be watchful
