Madoff promised 0.83% per month using magical arbitrage strategies and the smart people knew that couldn't be real.
probably you don't know how High yeld investment work.personally I partecipate since 2008 to a Private Placement Program with 1.5% per month of revenue. I receive CASH every 3 months (not numbers written into a paper or pdf file...). Obviously is not a program for cheaper investors.....
The problem is to choose a right company for the investment

Personally I trust bitcoin-trader and I have invested a small amount, reinvesting everyday the revenue. With this procedure after one year you have initial_capital x 10. On these investments the rule is: invest the amount you can loose without problem
I'm conscious bitcoin trader people can go away with clients cash, but this risk is everywhere. If you don't love the risk, keep the cash under the bed
my 2 cents
