How secure is $BTC really?

Let's break down the numbers:

$BTC's SHA-256 mining difficulty sits at ~110T. That means you'd need more hash power than the entire network combined to even attempt a 51% attack.

Current network hashrate: ~800 EH/s
Cost to match that? Billions in hardware + energy costs that would bankrupt nation states

And even if you somehow pulled it off, you'd crash the price instantly, making your attack economically pointless

This is why $BTC has never been hacked at the protocol level in 16+ years

The math doesn't lie. The incentive structure is bulletproof
