Many critics, detractors and anti-Bitcoin out there think that Bitcoin is a ponzi scheme for no apparent reason / argument. Ponzi schemes are a fraudulent mode that relies on money from new members to pay off previous members. We know Bitcoin has its advantages and disadvantages, but I personally don't agree if Bitcoin is said to be a ponzi scheme because no one can cheat Bitcoin transactions, even though Bitcoin holders or investors will be able to gain or lose, What do you think, do you agree if Bitcoin said to be a ponzi scheme, and what is your reason ?.
