Support for additional cryptocurrencies should be a priority

Hi,

I know that on the support page it says that support for additional cryptocurrencies is "coming", but the two that are supported are nonideal for small donations - especially BTC where the transaction fee alone can be over $1 - adding support for some of the other popular cryptocurrencies that put a focus on cheap payments (bitcoin cash, litecoin, dogecoin) seems like an easy win.
