I have seen his account is not active from a few years in this forum, is he in depression or something cause I would be if I were to be him.
Last time I checked he had children and was enjoying his life, not depressed at all. Some people get over such things.
Life has much more to offer than early retirement.
He's not depressed, he was posting on the Bitcoin devs mailing list on 15 Aug 2015. He's the first dev to code an open source GPU Bitcoin miner, and he used it to mine those pizza Bitcoins. I think he'd rather post on a techy devs mailing list than here because he's likely to want to discuss techy stuff.
