Can Bitcoin Survive Attacks from State Actors?

It's not easy to control Bitcoin. The real money is in benefiting from it, not trying to destroy it. A coordinated effort against miners could do damage, but Bitcoin would survive.

Exactly! If they manage to attack, it could ruin Bitcoin's reputation, and if trust is broken, no altcoin would be safe either. But with around 18,000 nodes running, they’d need to control a huge number to pull it off.
