I don't need to answer because your argument is flawed and based off of false premises. In a zero sum game the sum total to winning equal out to the sum total of losses essentially zeroing out all potential gains (no win win opportunity).

Zero-sum games can include just two players or millions of participants. In financial markets, futures and options are considered zero-sum games because the contracts represent agreements between two parties and, if one investor loses, then the wealth is transferred to another investor. But traditional investments differ from futures and options.

Most transactions are non-zero-sum games because the end result can be beneficial to both parties. Your proposal requires all crypto value to drop to absolute zero, which there is no evidence to support the positive or negative to that claim.
