Bought some on cryptsy and I thought this should be fast one but 0 confirmations in 10-15 minutes.
If you try to run modified code on this network your IP(s) will be banned by the nodes FYI. So do not experiment with it without generating your own genesis block, using your own ports, and you own IRC channel. This is automated.
You can't just change the difficulty and block times on a whim. You have to hard fork the chain which can lead to disaster.
I think a hard fork may be the only option here. The difficulty adjustment times are simply too slow.
You may talk about block rewards offsetting the fact that mining is slow, but traders don't care about that sort of thing.
Spikes in difficulty destroy the profitability of the coin.
