It's hyip and scam people soon!
The lower are the given interests and the easier (and less confusing) will be the management of the HYIP.
And the longer the ponzi site survives, the past has shown that hyip sites that offer returns of 0.25% to 1% per day have survived for years. But of course for a hyip site to survive for years will depend on the good management of the program administrator
Do not make that mistake, however much a hyip site pays today, there are no guarantees that will pay forever. With that said, I do not invest in hyip sites but I'll give you some advice:
If you have already invested your $100 you should wait until you to recover your principal and you should not invest more money out of your pocket.
Is not there a safe way to improve our money? Gambling sites are very unreliable. Is there a safe investment way you know?
