help Mr. Blue FAQ

Is Mr. Blue a legitimate German investing app or a scam?

German retail investment apps must operate under BaFin-regulated custody and deposit rules, the same framework covering large neobrokers like Trade Republic and Scalable Capital. Before depositing, verify the operator's BaFin registration and which regulated partner bank holds your securities.

How do Mr. Blue's fees compare to Trade Republic and Scalable Capital?

Trade Republic and Scalable Capital charge around €1 per trade, so a broker with meaningfully higher per-order fees gets expensive for small, frequent fractional purchases. If Mr. Blue's fee schedule exceeds that, beginners with €50/month savings plans lose more to costs over time.

Can I buy fractional shares of US stocks and ETFs with Mr. Blue?

The app's core pitch is fractional shares, but its asset catalogue is limited compared to Trade Republic, which lists thousands of stocks and ETFs. Investors who want specific index ETFs should check whether the exact ISIN is available before funding the account.

Is Mr. Blue good for complete beginners, or should I just use a robo-advisor?

A simplified self-directed app suits beginners who want to learn by picking their own fractional positions. If you'd rather not choose anything yourself, managed portfolios like Scalable Capital's robo-advisor or Germany's Growney handle allocation automatically for a percentage-based fee.
