Sooooo I have to be late to this party...but I was adjusting my settings on Gravatar which I honestly never use and saw a tab that said "Crypto-Curriences"
Wait whattt?
Interesting!
They accept Bitcoin, Litecoin and Dogecoin currently.
So this can't be new right? I mean I haven't touched Gravatar in ageessss so I'm sure someone else has seen this right?
In case you've lived under a rock like me...now you know!
