What a dumb concept. Trying to control decentralized free trade. Even the FED said they can't stop Bitcoin. Just let market forces work its magic and many coins will die anyway and if they don't then someone wants to buy and own them so who the hell are you want to stop them doing what they want.
Its always the younger generation that wants to control the free market, it bodes badly for Capitalism in the West. And don't use the V anonymous mask, your views run in opposite to revolution and freedom.
It's exactly because it's decentralized that we can, really. Free market in both directions. How do you know there isn't federal involvement in trying to discredit Bitcoin? Or banks buying up BTC and manipulating market prices?
Of course you can control altcoins. It's still currency. Decentralised or not you can still manipulate the markets. That much is obvious.
