Ex-RBI chairman said "Bitcoin is creating money out of thin air". It is biggest scam of all. 
sorry if this is a fraud why many bitcoin investors are successful by benefiting from the investment, if it is bitcoin it is a fraud why there are still many investors who invest in it a little my thinkingBitcoin is not a fraud, but if it is then why a lot of governments of every country supports Bitcoin? Bitcoin may have a surprising price every now and then but we all know that Bitcoin's price is dependent on the demand and supply. With a lot of whales, a lot of supporters and users of Bitcoin, it is far from being a fraud, it is just becoming more of an asset.
