The answers to your question are there.
Not really. At least in my case the problem is not unexchanged currency. Its that I don't earn as much as I did until friday. This morning I received .0098 at a 1220 Kh/s rate. Does that seem normal? I only have .0006 unexchanged right now and .009 immatured. These are low figures.
Yeah that is quite low. In my case I have 0.02 immature due to the exchanges issue.
In your case, don't know. We could also be affected by the crazy drop in BTC yesterday that pulled the Altcoins down with it.
yesterday there were 12 hours with no blocks at ll (as per graph). But the pool is getting way too big making a huge impact on the coin where it lands. Maybe is time to go mine as per coinchoose
