I'm having the same issue as everyone that's posted since March. I've tried adding all the nodes listed on the last two pages, but the Core wallet still doesn't sync on Linux. Has anyone been able to get the Core wallet to work on anything besides Windows?

Your math sounds about right. With 5 sticks running for two weeks on mmpool, my estimated round payout is .00030723 btc. At BTC's price right now ($4150), my 5 sticks would make roughly $33.15, and would pay for themselves in seven years. LOL ...I'll try solo mining and hope I win the lottery.

Has anyone had any luck mining with these? I've been mining for 2-3 weeks on mmpool and haven't earned anything yet: http://mmpool.org/user/guttermonk

So I tried switching to mining BCC on suprnova for the last week and haven't gotten anything there either.

My miners are running on cgminer at 135MHz with no errors.
