It’s very unlikely. There’s about 10-15 years before it would even become a concern. It assumes btc gets no traction and the chain usage doesn’t pick up at all. In other words if btc fails it becomes a problem! Lol. There will be massive hash rate increases due to stranded methane and stranded energy. It’s very unlikely with hash going exponential and the Decentralization of hash that comes with the above, that any state authority could gain 51%. Bc as we know, it has to be an attacker that doesn’t want to make money, otherwise they would just mine btc. Also, even if someone did get 51% the settlement time and finality is pushed back. No coins are stolen.
