Practical choice criteria
Start with purchase costs, availability of the ETFs you need, ease of use and support quality.
Only after that consider advanced features that are often secondary for beginners.
Common mistake
Choosing the broker only for the lowest commission without considering taxation, operations and reliability.
A slightly higher cost can be acceptable if it reduces friction and errors.
Before opening the account
Always check updated conditions on the official website.
Also verify which markets and instruments you will actually use, to avoid unnecessary accounts.

Compare two brokers in a personal table: real annual costs, tax regime, required instruments and ease of use. Decide calmly, but decide.
