Lets say bitcoin reaches 1 million in 2040 and by then you own a few coins.

Imagine you're an average to above average income earner and you steadily invest into bitcoin and over the years you accumulate 3-4 coins. Imagine now its 2040 and you're sitting on a 4 million dollar portfolio but you're making only 80k to 120k at your job. How do you get the nerve to not sell and retire early? Or sell off some of it and reinvest into something considered more "stable" how do you stomach as an average joe watching your massive portfolio get cut in half from a bear run.

The question im trying to ask here is how will bitcoins trajectory to 1 million and beyond resist profit taking and people wanting to escape the rat race. Or mega holders selling off their portfolios slowly to invest in real estate or something.
