RE: Publicly Traded Bitcoin Miners Make Up 20% Of Hashrate

The weird thing about double spending is that while it's technically possible in theory, it's basically impossible in practice.

For example, let's assume a corporation has 51% hash rate. They decide to double spend Bitcoin. Okay... so what are they going to buy with their Bitcoin that can't be reclaimed by the owner after they roll back the chain? Certainly nothing in the physical world... they'd get sued assuming they could even make the trade in under 10 minutes. Oh wait they'd get sued no matter what because they're a public company. There's no way they could pull it off even if they wanted to... which they wouldn't because they'd lose billions from corrupting a network who's niche is trust and security. Best they can do is blacklist wallets from their blocks.
