That is a huge profit and long way to go. I think you should forget that you are holding a bitcoin since it will take decades or more to reach this, but Bitcoin is very volatile, so we really don't know. If you continue to monitor the price of bitcoin on a daily basis, I believe you should lower your target price, even if it reaches $100,000, because you've already made a lot of profit on it. My plan is I only sell it when I need it, so it will be a few years before I sell it, depending on the price so that I do not lose money.
I think huge expected and almost seems impossible with Bitcoin price target above $500,000 current price right now still under $17,000, I think many people over confidence when targeting about Bitcoin price until $100,000 without check with current price early. I know with any impossible thing in cryptocurrency and Bitcoin potential reach highest price, but think realistic with Bitcoin still under $17,000 in this month and drop price at this years seems little possibility for Bitcoin can reach highest price again above $100,000.
Sure Bitcoin have potential back to higher price again but I think stuck under $60,000 seems realistic with many community will used short position at future trading and make many bad news for Bitcoin can drop after reach highest price.
