I assume those prices are monthly fees? Anyway I don't like the idea of anonymous spending for the sake of anonymity. It is a "feature" of the Bitcoin currency, but if they really want to support the Bitcoin currency couldn't they just accept them for regular Digital Ocean accounts ?
The site is not run by Digital Ocean, they have said they will never accept bitcoin. We are basically reselling them :)
This is cool, but I suspect that the reason Digital Ocean doesn't accept Bitcoin is not technical, but more to do with the sort of customers that would want to pay anonymously.
