I have some bitcoin sitting in my BTC Wallet doing nothing for the past several months so I decided to invest a portion of it in High Yield Investment Program (HYIP). Please note that I do NOT recommend investing your money in HYIP. The return is indeed much higher, so does the risk. People have lost thousands of dollars in HYIP. To minimize the amount of money that I may lost in case the program suddenly stop paying, I make sure that I requested Referral Cash Back (RCB) from my referrer.
