The chances of Bitcoin to 500$ is equally zero. If it happens the market will be flooded with largr investors that will buy all Bitcoin before it get to anyone.
Buying low is always an advantage, so i expect everyone who comes across Bitcoin at that price to buy more, but the possibility behind the imagination is far from reality. Where we see Bitcoin now is to hit $1million very soon.
Yes, the chances of that happening are almost 0 but if it does happen, it means bitcoin will lose 99% of its value. So I doubt big investors will buy it regardless, as it's not a normal dip. Because no asset with so-called potential has such a crazy drop. If that happens, it will be the end of bitcoin and the cryptocurrency industry, and instead of bitcoin recovering, the possibility of bitcoin price gradually falling to 0 is much higher.
But again, the chances of that happening are pretty low and close to zero.
