only 1k$ left for bitcoin to reach 5k$ so I think it can reach 5k$ in this year but if you need bitcoin price reach to 10k$ or 50k$ maybe you need to wait more few years or maybe something happen like August 1, it can help bitcoin price increase very quickly

As you have mentioned we can see that $5000 could be around the corner anytime soon. But to reach $10000, I think we need to see a new set of investors that are willing to enter with huge volumes of cash with them. Or another country will join the picture like Japan influence on the price when it legalized bitcoin. We are not yet globally adopted that it why its really hard for bitcoin to see another level of price movement. Although bitcoin is now famous more than even, but the mere fact that only a small percentage is owning bitcoin, I doubt that we can get to $10000 next year.
You mentioned Japan, I think so too, the more countries legalize bitcoin as Japan, thea more is its price.
