Right now things doesn't look good. Anything below IPO price is just not good IMO.
Profitability with this price/diff just isn't good.
A saw some multypool jumped in, and now when diff is up and price is down they're out, so I'll do the same, pulling my rigs from CAI.
Many shit coins will gain more than CAI right now.

profitability will gain from the increased hashrate. You need to remember the only one selling CAI now are the Miners, the traders buying will not sell at that price, as difficulty increase, price will go up with it as well. As those miners will not afford to sell at the same price. We have less output in coin than a lot of coins. With our first app release this week we will stir interest and people will know we are serious about this. I mined coins at 1 satoshi and sold them at 130 satoshi, that's what I call a real win. By now also everyone noticed the devs and investors are not dumping CAI. That should be a hint for you.
My theory with mining is this. If it doesn't look good it isn't and don't wait to get better. With trading is - If it looks good don't wait to get much better cause it could end much worse.
I wish I stick with that theory with UTC, also slept over BC dump :-) but still 500% up and holding, ... so, with CAI we'll see what next week news will bring. I have enough CAI's from when diff was 7-8-9 so CAI's are in wallet waiting for at least IPO x 2 price and until then I'll be watching, Wish you all the best with mining and trading decisions.
