And how long do those 3 mining pool operators need to doublespend to destroy trust in BTC.
Less than ½ hour,
and if they are on an exchange or markets that lets them short BTC or short companies that own BTC,
they could become insanely rich in a single day, and no longer need to run a mining pool.
1. 0.5 hours would be difficult since some exchange require 6 confirmation.
2. Huge withdraw usually is reviewed manually or checked more thoroughly by the system.Does not Matter, all that matters is a doublespend happens, and trust is lost. Amount is irrelevant. 3. Unless they swap BTC for decentralized altcoin, they face risk their fiat or altcoin frozen or reversed.Does not Matter, all that matters is a doublespend happens, and trust is lost. Amount is irrelevant. 4. They'll be arrested unless they could secure cooperation with various corrupt government worker. Doubtful you know who they are, or they claim they were hacked,5. etc.Some exchanges only require 1 and many only require 3, which is why less than ½ hour was listed.
Plus the money can be made shorting all bitcoin related stocks on stock exchanges.
