Does anyone have a list of coins where soloing is known to be broken?  Maybe one with low diff? Wink


Phoenixcoin has low diff and the blockchain should download fairly quick for the wallet.

I find blocks in a matter of mins. after starting r54, r55 & r56 gives more boooo's than r54 that I get none in.
-i value needs to be low -i 10 is a good starting point for solo mining phoenixcoin.
at 300+ kh/s I find a block in about every 15 mins most of the time on a single GTX960.
