What is the truth about the HYIP programes promising 150% after a month ?

HYIPs offering 150% in a month are almost always Ponzi schemes. That return implies 12,975%–5,960,000% annually—impossible for any legitimate investment. Avoid, don’t refer friends, and withdraw/report if you’re in already.

HYIP are all scams. You can make money if you get out before they dissappear, but I would nnot advise it.

this is a scam, the HYIP is not made to make money, they'll ruin. AT first you win, once you bite the bait it's over.

You could win only if you out-smart the owner

All hyips are gambling. You could win only if you out-smart the owner. Hyip definitely collapse once the owner collect enough money from investors.

I definately would not sign up to any Company promising you such returns and in a short space of time. I would rather take my time and learn from the bottom up - even if it took Month's before seeing my first profits. Stay clear I say.

They are Ponzi Schemes, best to avoid them.
