If your household income is < $125k you can appreciate a gain up to the difference without paying capital gains, hopefully you live in a state without cap gains.

E.g. if you make 100k and have 50k of bitcoin that you bpught for 30k and held for over a year, you can sell it, see a gain of 20k, and keep the total annual income under 125k which is taxed at 0% federally.
