For reference, a quick Google search says there are ~1 million bitcoin miners. However, presumably there's a pareto-type distribution where some some small% of miners are responsible for the majority of the hashrate, so I'd be curious how many miners would need to agree to dictate the direction of Bitcoin. This is also probably complicated by the existence of huge mining pools and relatively apolitical miners who would go along with whatever client upgrades the pool said was required to keep mining with that pool -- although, OTOH, switching pools is not particularly difficult. Something that's interesting to me is that forking the blockchain creates money out of thin air, if people accept both sides of the fork -- I've seen people who recovered old wallets make sure to collect the extra bit from Bitcoin Cash along with the main windfall of regular Bitcoin. If blockchains really do take over finance, there's interesting implications for inflation control / monetary policy there, I think.
