Graph aside, price movement are an indicator of market sentiment. If an asset is not deemed as a 'safe-haven' or whatever they call it, then the price will move accordingly. In short, if more and more people starts to believe that bitcoin (or any asset) is a good thing to store their wealth, sooner or later the price will follow. It's safe to say that if we don't see that yet, then the market still don't fully trust it even if the potential is there. Time will tell.
Isn't that one of the biggest gripes with crypto? That only time can tell many of the benefits touted over and over online? Not being critical of it, I agree though that the fact that current bitcoin price mirroring the stock market is mimicking people's sentiment rather than the US stock rate.
