Tbh I think Bitcoin’s final boss is validity at scale. It’s survived lots of mini bosses like forks, exchange hacks, and skepticism. But in the meantime the real test will be whether it can stand firm against co ordinated regulation, public pressure over energy, and  challenge of scaling without losing decentralization. Time is also a hidden enemy  itself if Bitcoin doesn’t stay relevant, it risks fading quietly. IMO, the ultimate will come during a major global crisis. can Bitcoin prove itself as a neutral, trusted settlement layer when the world actually needs it? That’s when we’ll know if it’s unstoppable or just another experiment for sure
