9 out of 10 $BTC experts agree: the difficulty adjustment is THE breakthrough that makes Bitcoin work.

Not the blockchain. Not proof-of-work alone. The difficulty adjustment.

It's the self-regulating mechanism that keeps blocks coming every ~10 minutes regardless of hashrate. More miners join? Difficulty goes up. Miners leave? It drops.

This is what makes $BTC's supply schedule predictable and unstoppable. Without it, the entire security model falls apart.

Yet most people still don't understand why this matters more than any other feature.
