Bitcoin is pure capitalism. No real work, no real goods and no values of something and not benefit for human kind. So it is just gambling. I've a bad impression of crypto-blockchain-digital-coin stuff which purpose is to make some minority richer. The founders of Bitcoin stated they want free free us from central-bank-money? The central-banks are hopefully the only institution people can trust in stability a little. Politicians should look up their laws, most countries only allow their official currency for trade and should limit exchange to official currencies of other countries.
