Who Should Choose Which Broker

XTB — choose if you:

• Invest in ETFs and want 0% commissions
• Are opening an IKE or IKZE
• Are starting your investing journey
• Want fractional shares (small amounts)
• Plan regular DCA investments

Bossa — choose if you:

• Need access to NewConnect and Catalyst
• Trade government bonds on GPW
• Are an advanced investor (API, technical analysis)
• Want IKE and IKZE with broad market access
• Already have an mBank account

eMakler — choose if you:

• Have an mBank account and value convenience
• Invest occasionally, not regularly
• Prefer one app for banking and investing
• Don't need advanced trading tools
• Primarily buy Polish stocks

Can You Use Multiple Brokers?

Absolutely — and many investors do:

• XTB for IKE (0% ETF commissions) — primary retirement account
• Bossa for IKZE — broad access + mBank integration
• eMakler for quick Polish stock purchases from within the banking app

You don't need to keep everything at one broker. Institutional diversification adds an extra layer of security.

Track Portfolios Across All Brokers

When you have accounts at 2-3 brokers plus banks and crypto — it's hard to see the full picture. Freenance integrates with XTB and Polish banks, aggregating all your assets in one dashboard. You see total portfolio value, allocation, and your Financial Freedom Runway — without logging into each platform separately.

Bottom Line

In 2026, XTB wins for most individual investors thanks to zero commissions on ETFs and stocks. It's the obvious choice for IKE/IKZE with ETFs.

Bossa is better for advanced investors who need NewConnect, Catalyst, and API access.

eMakler is the convenient option for mBank customers who invest occasionally.

Regardless of which broker you choose — the most important thing is to start investing. The commission difference between brokers is far smaller than the difference between investing and leaving money in a current account.
