You can open a retirement account with a minimum initial investment of $3,000, or a $100 monthly contribution for a Saver IRA. There is no investment cap. Retirement accounts that hold Bitcoin require significantly more steps and procedures than with cash purchases. Bitcoin IRA provides a full-service solution that facilitates the process for account set up, rollover of funds from an existing IRA custodian, access to our self-trading platform, and moving funds to a secure digital wallet for all retirement account types.
