How would you rotate your 401k/IRA shares into self-custody BTC without taking a early withdrawal penalty and incomes taxes?
Unchained capital (and swan as well i believe) offer IRAs that are self custody multisig accounts. You hold 2 of 3 keys and they hold 1 of 3. You can do a transfer without penalty/tax as long as you don't withdraw that bitcoin. The great thing is you can still withdraw it whenever you want without permission or delay. You'll just get a tax bill at the end of the year.
