No investment is safe, especially with Bitcoin. The price is very unstable, so it can go down at any time and your investment will be over. When investing in anything, you need to assume some risks. There is a benefit only if the price keeps growing, like it did in the last few weeks, but do we know when it's going to stop growing? We don't. The scenarios of countries accepting Bitcoin is unlikely, at least at this moment, except if they want to experiment some kind of a test on us.
