1. Small blockchain - bitcoin out
2. 5,000,000+ pre-mined coins - Tenebrix and geistgeld out
3. Already crashed - fairbrix out
4. Horrible Difficulty algorithm - namecoin out
Seem the only one left is ixcoin until solidcoin comes out and replaces them all!
We need a new exchange.
ixcoin is not viable right now, they need to fix the time warp bug at least. I also think they need to revert the asymetric difficulty changes.
