I cannot even determine if it safe and reliable to mine trc... Or even predict my daily coins earned. This has to be the most confusing alt. What does 1 g/h earn right now? The diff also bounces around so much i am unclear if the core prob from a few days ago is resolved.
It seems the core problems from before are resolved and things are more stable now. Coinotron turned their pool back on, at 400Gh+ atm.
As far as earnings go, that's hard to say because the difficulty does move around a lot. When it hits the 5255 floor it seems quite profitable at the current price. The surges in difficulty come and go, they don't remain constant.
http://www.cryptocoinexplorer.com:3750/chain/Terracoin?count=20miners bumps too (causing this diff movements?) ; check coinotron for example, number of miners and TRC hashrate more than doubles every now and then
