Bitcoin Doublers are regarded as the highest risk of all the different “High Yield Investment Programs” (HYIPs) that exist. This is mainly due to the high payout and consequent short life span, but other factors include bad management, greedy administration, poor server setups which are unable to handle high traffic loads, or API problems which prevent investing and payouts. The high-yield percentage varies, but can be anywhere from 0.1% per day to over 100% per day. Compared to cash deposits, which may return 2% per year, and you can understand the appeal. But BEWARE: All HYIPs are SCAMS – they will all unplug at some time and disappear with your money – do NOT be fooled by any of the promises on the website home page. They are true Ponzi Schemes.
Regardless of the promise of what is stated – HYIPs simply take investors money, dump it into one pile, and then pay early investors the promised interest from the pile. As more and more investors come onboard, the pile continues to grow – and when their goal is reached, they disappear with the pile of money. Obviously, you lose if you didn’t get out in time.
