At the early stages Russia ruled it as illegal, China outlawed all withdrawals and some other country also spoke against it. But now everything seem to be smoothing up at least on the government side. Surely Bitcoin must be seen as challenging their authority. Is there something I am failing to see? All it would take is a 51% attack or a new law.
I think the governments of Russia and China have recognized the value of Bitcoin. I and my friends saw the great potential of bitcoin for the world economy.
Current countries in the world are very interested in foreign trade, because their country only develops when it has a better change in all aspects. Therefore, bitcoin is very useful for foreign trade when trading through countries is not a big problem for it.
