If That's the Case then btc might drop to Zero.
Drop to Zero, really, are you serious?
So absolutely everyone currently involved in Bitcoin is going to totally abandon it,
people stop buying and selling, miners have nothing to mine and turn their thousands of hardware units off,
developers turn their computers off and stop communicating with each other, and so on and so on . . .
that is not going to happen!
bitcoin involvement in general will always change depending on what developments are made in adoption, rules and regulations made by various governments, FIAT value, hype and general movements in trends towards it. If one group of people declines another will grow but overall adoption and interest in Bitcoin will increase and that may not always show in the FIAT value.
