Regardless of what fhs price of Bitcoin is right now, it is important to know that, investors will never see that price hyke as any thing stopping them from buying Bitcoin, because at a point what determine our purchasing power is the availability of a free cash at hand, because to some people, when bitcoin was at its lowest price, they can afford it, of not having the money to buy.
But now that they have the needed cash flow to invest, the price is not gonna stop them, and at the end, if they hold for the long term, at the right time, they will also be in profits like those who bought at a low price as you said., so the sure Bitcoin can never get to a stage where it becomes too expensive for those that want to buy at whatever price.
