Sure, but topic is not about BTCCoin here.
Imagine people in undeveloped countries? They will never be able to mine BitCoin.
What they do have is some older machines still capable to mine, so they could get some taste of Freedom.
Also, I really like a few ideas of others to create coin where with older machine solo mining is promoted and new people get some incentive just as they start to mine.
I like this idea too, and I think it was the original vision for Bitcoin. By the time it became clear that GPU mining would dominate, it was already too late to do anything about it. ASICs just make a bad situation worse.
Universal mining on CPU would have seen a much wider spread and adoption of Bitcoin during the press frenzy - the lack of GPU resistivity was a major flaw that has hindered Bitcoin. Tenebrix->Fairbrix->Litecoin sought to address this, but they have all failed in this objective where GPU miners dominate.
I'm currently creating an altcoin with universal CPU mining ability. Send me a private message if you'd like to be in the beta.
