I think BTC is about done with it's downward trend.  It hasn't touched it's low in over a week if I'm reading it right.  A 1/3 value adjustment after that landmark runup is healthy for the overall market.

Let's get some discussion started about immersion cooling.  I think that it may be a way to bring old equipment back into the fold, as well as bring operating costs down.  I picked up a cheep S4 as my entry into mining and realize, that once heating season is over, I'll likely need to turn it off unless I can cut some corners on power consumption.  I can run it half the year here, just as supplemental heat no matter how sad it's coin finding becomes.  I think nearly 225w of my unit's overall 1300 is fans.  With half a dozen empty aquariums in my basement, and a Sam's card where 20gal of vegetable oil will cheep... I can't help but wonder if oil cooling isn't the answer.

I plan on trying it out on some old equipment next month.  Just an old mobo and old NVidia card that can just barely mine ZEC with it's memory/cuda count.... a 550ti I think.  I will share my results.
