Why Does Broker Choice Matter?

A broker is the foundation of your investment journey. A good broker can save you thousands of PLN in fees and make investing enjoyable. A bad broker is a nightmare — high costs, poor interface, technical problems.

Remember: Changing brokers later is possible, but costly and time-consuming (portfolio transfer can cost PLN 50-100 per position).
