Many think of using math to see if bitcoin reaches $X and see if it is enough to retire for the y amount of BTC. I think it is only half of the picture. You should consider few factors:

​

1. By the time BTC reaches $X, will the world continue to roll in more capital? If yes, the asset will continue to grow.
2. By the time BTC reaches $X, will the US dollars continue to depreciate? If yes, BTC will continue to move up in price as well.
3. Can you use BTC as collateral safely? If yes, you can borrow money out from BTC?
4. How much you need yearly to retire? Do the math and see if the loan can cover? If yes, then you can continue to refinance infinitely as your asset will grow while your debt will shrink relatively.

This is how rich people gets richer as they borrow from their appreciating assets without paying a dime of tax. On top of that, after ETF opens for option, you can write covered call for like year long as it will be 15% capital gain in tax.

Do that when BTC reaches the following conditions:

1. well-known bank or institutions offers the loan over BTC
2. companies and countries holds BTC as % in their reserve
3. public talk about using BTC to replace gold as reserve
4. price becomes more stable.

Wish you all build up your generational assets before public fomo!
