I used to invest in "doublers"
I tried to be among the firt investors...
Globally I have lost a little...but it was more because the ponzi runners were scammers...not because the ponzi's itselves.
I prefer now investing in my own systems

What system you have develop can you explain ..so i can see if this real or again scam investment option
My systems are definitivemy not ponzi shemes.
No promises in advance (in general only ponzi can promise in advance)
my 100 days plan the only promise is the money back before 100 days + profit if profit + free booted cash.
my U2cloudmining system does promise even less...money back if shares are sold + profit if profit.(investment can be paid or for free)
Wrong people take it for ponzi shemes...I cannot forbit it (lol)
If people believe that it is "ponzi sheme" and want not invest in ponzi sheme...then I advice them to avoid (lol)
If "zero" investors...then all profit (ok less) is for my self...
I have lost much sweat last 2015 to contra-argument my detractors...
now in 2016...i let talk peacely them...
Have a Happy New Year 2016
