In my opinion, I think it's quite late to invest in bitcoin now, the value is very high, which means that the risk is quite high either. Rather wait until the value of bitcoin is stable and buy bitcoin. Alternatively, you can earn it through bounty campaigns etc.
Maybe.. But remember, bitcoin is not yet accepted on other countries. And i think global adaption may happen. When i heard that Russia will compete against China in terms of mining bitcoin. This makes me believe that this may open the eyes of other countries to adapt this kind of technology. Bitcoin is just beginning to expand. I know the price is quite high. But bitcoin will never go back to it's past price i tell you that.
It's worth to invest. It's never too late. Buy as long as you can. Because the movement of it's price is very surprisingly fast.
