Welcome back to Confessions of a Crypto Miner… my bi-weekly column about a crypto miner from 2013 trying to get caught up with the latest standards. I'm presently mining and reporting to you from a dual GTX 1080 based rig mining zCash.

In the last entry, I got my hardware & software set up and started mining. If you were monitoring the miner via the stats link, you may have noticed a few offline moments 2-3 days ago. This was due to me installing a nice new power monitoring setup and taking some measurements at different settings, all with the goal of finding the most efficient way to run the miner long term, to maximize profits. We now have all the data on hand and can now draw conclusions from it. There are two things I'd like to investigate with this article: 240 VAC's impact on power draw, and how the graphics card power limit setting affects profit margins.

As I have mentioned on the forums here at TechPowerUp a few times, I was an active crypto-miner during one of the most tumultuous times in crypto history: The period between 2013 and 2015. Rather than tell you a long and sad story, I will say just this: I ended up with a net loss by the end of this era, and it wasn't a good time to be an investor if you didn't like roller coaster rides. The reasons I lost money are many, but I think I can attribute them to primarily a lack of experience, a lack of written records, and really, a complete lack of a plan.

My New Plan
Yes, I'm planning on mining again. I've always been drawn to the tech, and I am in a much better position to do so now. Ironically, this time around, I'm not really in it for the money. I've already been there, done that, and it's too stressful for me. Having no end goal of riches doesn't set me up for failure. I think it is a more realistic mindset for taking on this project. It also gives me a chance to document my endeavor to the world, and to you, dear reader. I hope we all learn something here.

Ah mining. The revival of an old craze. Who doesn't want to make their room's temperature increase to insane levels over the summer in order to cash in on the mining wagon? Who doesn't want to pull their hardware by the ankles and wrists, stretching it in utilization so as to maintain the PoW (proof of Work) cryptographic security in cryptocurrencies? Apparently, a not insignificant number of users and would-be miners does want that. That has, in turn, placed a whole lot of pressure on the graphics card market from both AMD and NVIDIA, with prices climbing and skyrocketing for graphics cards in the $200-$400 price ranges, as you know. It remains to be seen whether the flow of new miners decreases somewhat now, considering the recent market correction (read: dip) in the cryptocurrency market value (down around 42% from the all-time high of 357€ [~$400] of June 12th.)

After ASUS, it would seem like it's Sapphire's time to try and sway miners from their consumer-oriented, gaming graphics cards, through the launch of five different graphics cards models especially geared for mining. These are currently available for pre-order on Overclockers UK, and there are five different products in total, one based of RX 560 silicon, and four different takes on the RX 470 silicon (no, that's not a typo; it really is the 400 series.)
