Regulated by whom? A centralized authority? Syndicates aka mafias? I can only speak for myself, but I sure wouldn't trust them.
Regulated by each and everyone of the countries where they are based.
Again, understand that I'm not referring to regulation that would allow for coercion of mining syndicates into maliciously using their power but regulation that would limit their hashing growth so as to secure the decentralization of the now global (in this scenario) Bitcoin economy.
You'd have no choice but to trust them.
I'm talking about centralization of mining and this crook Sam Cole milking BTC for fiat. Meanwhile, you're talking about BTC becoming the dominant world currency and decentralizing the global economy? I think we're on totally different pages.
