Confessions of a Crypto Miner: Green(er) Mining

Welcome back to "Confessions of a Crypto Miner," my 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. Today, I'm going to talk about saving energy and reducing a miner's impact on the environment. How can you do that, you ask? Simple: Consolidation.

Mining inherently consumes a lot of energy, but a lot of things we do as tech geeks are actually not all that efficient. Case in point, my NAS I've had for years. Old Lenovo server-something or another, modded pretty hardcore, but still energy-drinking to the core. It's based around a Core 2 Quad and uses around 400W of power on its own when not doing much of anything more than being an NAS. It features big RAID arrays and big blower fans, none of which I really need in this day and age and all of which consume power. I've been thinking since I got my Ryzen quad core mining rig: What's to stop me from mining and doing my NAS stuff on the same rig, thus saving power? As it so happens, not much. My miner has the same memory size as the old Lenovo DDR2 solution and a far more energy efficient, likely faster CPU. So I can fold that 400 W server into my 550 W of mining, far reducing my footprint in a green sense. Let's get to it.

Confessions of a Crypto Miner: CPU Mining

Welcome back to "Confessions of a Crypto Miner," my 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.
Today we are going to take a look at mining again - using the CPU in particular. CPU mining is the original form of mining cryptocoins.

Confessions of a Crypto Miner: Storing Your Coins

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.

As requested by many readers, today, we are going to talk about safekeeping your digital currency, and particularly, how to do it safely. Crypto has gotten a bad rap as of late for being insecure, due to numerous hacks of exchanges - but the cryptography in it is actually very strong and solid, and nearly all hacks have been related to centralized services or bad practices.

The focus of this article will be how to hold coin safely for the purpose of investment. I will go over the types of wallets, and their pros and cons. It may seem a bit more technical than some of my usual works but it is very essential information that everyone considering crypto should know. I've done my best to boil it down to basic, easy to understand principles for you.

Confessions of a Crypto Miner: Efficiency

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.

Confessions of a Crypto Miner: The Setup

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.
