Bitcoin has come to stay and in many decades to come, bitcoin will be used as store value or reserve after the adoption rate has become so high, by the time the adoption rate becomes high, it is expected that the  price of bitcoin would have almost turned to a stable coin then because of its very low or no volatility in its market.

That would be in the future though, but for now, I doubt if bitcoin is really good to serve as digital gold now, since we are still at its early developmental stage and the market volatility is still very high. So bitcoin serving as digital gold in future could really change the world.
