one way to minimize your tax liability in the USA: if you mostly just hold for long periods of time, consider aiming for long term capital gains: if you hold for at least a year, your gains are taxed at a lower rate, usually 15% for most people. short term capital gains are taxed at your regular tax rate (up to 40%).
So much this.
You should also try to avoid crypto-to-crypto trades because each instance is considered a sale and a purchase.
If you want to take extreme measures, move to
Puerto Rico lol.
