So having heard nothing for a while from the founder I perused the dedicated GPUcoin website yet found nothing recent there save about 81 spammy posts from some user calling himself paterickfag. Maybe I got left behind here and everyone else is hanging out somewhere on a GPUCoin smartphone app? At any rate, I decided to get out while I could get still my mining investment back. It was I who tanked the coin on Yobit today - yes I'm the idiot who bought the book this time. Weak hands have left the building.
I actually made a little bit on this venture but it's not nearly enough to retire on (as I had hoped) so I'm going donate a tiny bit to a worthy charity. I'm creating a bitcoin address that begins with 1GPUCoin from which I will send the coin. I'm thinking in some way it will immortalize the existence of GPUcoin in the bitcoin blockchain. I would appreciate suggestions for charities that accept Bitcoin. I'll update here once the donation is sent.
