I think they governments are unsure how manage cryptos. It takes so much control away from them that they are terrified, therefore their first reaction is trying to stop it. Exactly what you would expect.
This 'fight it' phase of the adoption cycle may last a couple of years but in the meantime technology will move forward, new business models will be build upon the technology and the momentum behind cryptocurrencies and the blockchain technology will be enormous.
In the short term FUD can make values swing wildly. In the long term there is no way they can stop it because of the power of the idea and the decentralized nature of the blockchain.
On a lighter note... @emuLOAD you'd be amazed how many houses have been bought with bags of cocaine lol
