 ## How to donate?
 
-We are using [GitHub Sponsors][], [Liberapay][], [PayPal][] and
-[SEPA/direct bank transfer][SEPA] for donations. Liberapay itself is also free
-software and run by a team of volunteers, but GitHub is a viable and
-well-recognized option.
+There are many ways to donate to the project:
+
+- **[GitHub Sponsors][] - recommended**, zero fees
+- [Liberapay][] - moderate fees
+- [PayPal donate@organicmaps.app][PayPal] - high fees
+- [SEPA/direct bank transfer][SEPA] - negligible fees
+- [Cryptocurrency][Crypto] - extreme fees
 
 Recurring donations are the best way to ensure a relatively stable income for
 the project and motivate us for long-term tasks and goals. But you can also
 donate one time.
