I couldn't find one. Would it be possible at some stage for GC to accept Bitcoin? I see that there are multiple options to donate via various bank cards and paypal as usual, but no BTC choice. Donations can arrive within minutes and without any third party theft (bankers) along the way. I don't like to use any of the cards on offer and they all give out way too much information when it's just not necessary. I would love to see a Bitcoin donation button. Thanks.
