Would love to see more options, especially Bitcoin.  I would like to do an annual renewal, but I haven't been able to renew for some time.  I'm not in a position to use my personal credit card and Vanilla Visa gift cards haven't worked for a couple years.  There are bitcoin merchant services that make it super-easy to accept bitcoin payments.  Most of them will quote the bitcoin amount at time of purchase, which helps with the volatility.
