Personally in my country it wasn't hard, just we had to use documents to buy or sell BTC. But recently our government and financial body stated that its better to avoid virtual currency, though no regulations or restriction is forced on us till now.
If the government simultaneously and warns and still requires documents when buying bitcoin, then I can not understand the logic of the authorities. Perhaps they fix the turnover of bitcoins for a particular user, but apparently this is a certain difficulty for them.
