Lets say a hypothetical you have 1btc in your hardware wallet today worth around 8000 and lets just say tmrw the price is now 8 million. You literally never have to work another day again in your life. What would you do??
Me: I'd buy some land in a subtropical environment start a garden and just stare at the sky all damn day....
That's relatively specific, interesting choice of a pastime. It would be nice to do something like that, but you might get bored of doing nothing after a while. I know that happens to me, a lot.
If I had 1BTC and it was then valued at $8m, I'd probably do little but watch the market and take the profit if it is projecting another drop in value (and the $8m is a very temporary thing), or I'd hold if the market was planning to go further upwards. But I would keep working, keep doing what I am doing, and accumulate more resources to pass down to my children so that they have more access to wealth in the future. Maybe start a business with that kind of money, since it would be mostly risk-free.
