probably now worthless coins, mined from an abandoned fork of some coin?

Correct me if I'm wrong but at current prices = 3MH/s @ €1765.15, it will take at least 130 days to ROI not including power costs. (0.03BTC/day @ 3MH/s).

The trend is that BTC/day/MH is dropping, so I'm not so sure this is a good investment...

What are your thoughts?

Switched to Clevermining yesterday, but seeing lots of disconnects today. At the moment almost every 5 mins. Guessing the pool hardware can't handle the load.

[14:38:23] Lost 3 shares due to stratum disconnect on Clevermining
[14:38:24] Clevermining not responding!

I guess this makes the rejects high as well, up to 52% on one of 8 GPUs. For now I'm switching to waffle.
