I don't member 15c exactly, but i member mining it on my CPU for one night, then realizing that i didn't mine a single block for the whole night it was running so I gave up on BTC for a year or so. Damn this ADHD generation
exactly the same here, dunno what the price was. I member it was May 2010, though. Had the client running for a couple days. It didn't "generate" even a cent and since I hadn't read the paper or anything really, I thought this bitcoin thing must be broken ;-)
fuck.
