I think in the future the value will not be determined by any government but by the world economy as a whole.
For me, Bitcoin is now very important because it made lot of people to change their way of living including me. Before, I tried investing and doing business using fiat to fiat platform but without luck it keep me on losing with the small earnings are not enough to support my family needs but when i joined the Bitcoin investments i earned more than i expected in which it change my way of living from very difficult to normally contented which enough to support my financial needs. So if Bitcoin will gone for sure lot of us will going back to difficulty that is why we need to use our earnings wisely because we don't know if Bitcoin is forever.
