2. Fidelity

A strong option if you prioritize a traditional brokerage. Fidelity lets eligible customers trade stocks and ETFs in the same app used for crypto. Its crypto offering supports Bitcoin, Ethereum, Litecoin, Solana, and Fidelity Digital Dollar, subject to current eligibility.www.fidelity.com

• Best for: Long-term ETF investing alongside a smaller crypto allocation.
• Important: Crypto is handled through Fidelity Digital Assets, rather than being identical to the securities account.

3. Uphold

Which is the best fit for you?

My recommendation: Start with Interactive Brokers if you want a broad investment platform. Consider Uphold if the ability to move between crypto and ETFs within one app is your main priority.

What to check for security

• Custody: Who actually holds your cryptocurrency and ETF shares?
• Protection: SIPC protection generally applies to eligible securities and cash at member brokerages, but it does not protect crypto holdings against market losses. Direct crypto may not be covered.
• Account security: Look for multifactor authentication, withdrawal controls, and clear recovery procedures.
• Fees: Check crypto spreads, conversion fees, ETF expenses, and withdrawal charges.

These distinctions matter: for example, Interactive Brokers says crypto assets are held with its crypto custody partners and are not SIPC-protected, while Uphold says its securities are custodied by Apex Clearing Corporation.www.interactivebrokers.com+1

One question so I can narrow this down: Do you want to hold actual cryptocurrency that you can transfer to an external wallet, or is buying and selling crypto within the platform enough? That distinction can change which platform is best for you.

To help narrow down the right choice, tell me:

• Do you prefer to own actual crypto tokens (like Bitcoin/Ethereum) or are you comfortable gaining exposure purely through crypto ETFs?
• Are you looking for a mobile-first app or an advanced desktop platform?
