Ex-RBI chairman said "Bitcoin is creating money out of thin air". It is biggest scam of all.

Bitcoin itself does not create money, so this statement is not true. Bitcoin is just a form, a shell. To make it gain value, it needs to be pumped up with money. We buy bitcoin and thereby increase its cost. You can also ask another question: if we bought bitcoin for 20,000 dollars, then its course dropped significantly, where did the air go?
