Bitcoin maybe cross 100k today, why are you thinking 500$ ? It's totally unemaginable. So calm and relax. See what are going on...
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.
For now, the chance is zero as it is still going in the mainstream market. But nothing is permanent in this world. So I would say, in the future that this technology will become obsolete. So we still need to prepare for such phase of this market. But for now, you can take advantage of the opportunities it can bring to your financial vaults.
