When choosing a platform, focus on fees, liquidity and tax treatment. For ease of use and low cost, Fidelity and Schwab lead. For self-directed crypto IRAs, platforms like iTrustCapital are ideal. And if sovereignty and flexibility matter most, consider pairing spot ETFs with a small self-custody position.
