Digitalcoin. An established coin approaching its anniversary.
It's fast, no premine, never forked, long term stability, is fairly distributed unlike Quark.
The endless "Quark was not fairly mined" BS really gets old. It wasn't. The coin was announced and mined just like many other coins that were released at that same time (June 13, 2013). It was announced that blocks would be mined at initial rewards of 2048 coins/block halving every 3 weeks. I mined it with a total of THREE machines running a CPU miner and did so for over 6 months. Yeah, that was unfair.
Keep spreading this uninformed FUD just because you read it in another thread though.
Edit: I do like Digitalcoin, for what it's worth, and have ever since it launched. Barritus did the best job of a fair launch that had been done at the time, and probably since...
