How often do the profits from the investment account decrease?

Ask the bank how often profits are calculated and distributed, on what average balance, and whether the published figure is final or indicative.

Differences in frequency can affect your available liquidity, even if the annual return is similar.

The figures, fees and limits in this answer vary by bank and change over time — confirm them with your bank or the official source before acting.
