I don't know the proportion, but coincidentally enough, I work at a startup that uses Stripe and we used to support bitcoin transactions (and thus refunds). I just asked a friend who's been here longer why we're not supporting bitcoins anymore and his response was "exchange rates were a huge pain" haha so yeah it is indeed convoluted to do refunds with bitcoins, but if we are to attempt to use them as regular currency for goods and services, we can't not support refunds. so we dropped bitcoin support altogether.
