Calling them an asset, instead of a currency, betrays how little the government agencies understand them, in my opinion. But they are getting there. I see the evolution towards being considered a currency as an inevitability, along with regulation.
My attraction to cryptos has less to do with anonymity and more with controlled supply. Governments eventually may be able to regulate cryptos, but they can't print them into oblivion as a financial weapon like they do to their fiat currencies.
