If you can help it, you never want to sell an asset. Especially the apex asset of humanity.
Leverage it if you need fiat, but for pure monetary purposes it makes no sense to ever sell Bitcoin. You sell, you pay capital gains tax and lose all future upside. If you leverage it (take out a loan against it), you keep it, pay zero taxes on the loan, and can refinance that fucker over and over (like a house appreciating in value in a real estate run up), and live off the leverage.
Unless you have no other choice, don’t ever sell it.
