Appstore policy sucks and it's been so for a long time.

We were probably some of the first people who had to deal with this headache when we were building a mobile bitcoin and token wallet on Counterparty between 2015 and 2017. I remember the review er said bitcoin, dogecoin and litecoin are only acceptable coin and some other weird criteria.

Seems Apple hasn't made too much progress understanding Bitcoin/crypto after all these years.
