i did this 2 years ago and ended up buying the same vehicle 1 year later... the bitcoin did go up in value, but i don't think it really went up all that much. i feel like the sales friction loss really needs at least a 2X on bitcoin to make it worth it because you end up selling the vehicle for 50% less and buying one for 50% more.

but if you are just looking to mix it up, it could be a great way to make a new one pay for itself. i have also heard rumblings that new vehicles may be cheaper this year do to oversupply or something.
