It may happen that your desired amount is not fully invested in some crypto, as you can only acquire complete fractions when executing your crypto savings plan.
Here you will find a calculation example as an explanation with the Bitcoin fractions.
If you invest the minimum investment of 30 EUR through your crypto savings plan and the current price is 4.50 EUR per 0.0001 BTC, you can purchase a maximum of 0.0006 shares. With the current rate, you invest 27.00 EUR instead of the fixed 30.00 EUR.
Your credit balance not invested with the savings plan remains in your cash account until the next investment.
