I do not understand, how people still believe in Doubler schame/script (whatever).
Look real...
How is it possible that someone double your money/bitcoin in only 96/120h 4/5days
?
"Double" it is 100% profit,
example: you invest 0.01
BTC/23$ your profit is 0.01
BTC/23$.
Which is the way where you can make a 100% profit in only 4/5days,
and of course make a profit for yourself it is over 100% profit.
One more thing,
we are not talking about a single deposit such sites have got (scams) much more pay than one....
Ask only one question yourself, how they make money?
