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.
Because bitcoin has a potential that maybe even government people see. Investors and businessmen see it so it could be because they can see that bitcoin can also add to the economic growth of the country. Though they may be broadcasting warnings to the people to be safe, but that doesn't mean that they are not pro-bitcoin. Well it mainly depends on the country's perspective. There are some countries that have already banned bitcoin.
