One reason I'm selling some #bitcoin right now: As a US citizen the long term capital gain rate for my status is $46,500 at 0%. If I do not take advantage of this, it's wasted.

So for example if I want to buy a house in 3years for $300,000 worth of bitcoin, I pay a lot of long term capital gains tax on that in the future when I want the house.

But if instead, in these years while I'm waiting, I sell $44,625 of bitcoin, take the 0% capital gain tax, and then immediately re-purchase the bitcoin, it adjusts my cost basis up by $44,625 per year. If I do this for 3 years, then when I'm ready to buy my house in 3 years, I have $133,875 of added cost basis, saving me 15% (or more) tax on all that.

If instead I ignore this opportunity and just hodl until I need the $300,000 I will pay dramatically more taxes.

Something to think about.
