I really like Zabbix. It’s open source, been around for well over a decade, and does exactly what I need for monitoring my gear. It gives me a dashboard I can check anytime, and sends me an email when there is a problem that I consider important enough to be notified about. The header picture […]
Small Bitcoin mining operations have some advantages over the large operations. This video discusses actions to take and skills to develop to maximize revenue as a miner with 30, 100, 500, or 1000 servers.
It seemed like a big deal when the Antminer T9 published the efficiency specification. It appeared to be much less efficient than the Antminer S9. The Antminer S9 went through a version change in about October of 2016, changing from fixed frequency hash boards to variable frequency. Bitmain also changed the warranty policy, extending it […]
There’s a lot to discuss when talking about Bitcoin Mining at Scale. I put together an introductory presentation on the topic. I’ll do more videos on this going forward. Check out this post I wrote last year about planning your operation: https://blockoperations.com/planning-your-bitcoin-mining-operation/ Here are a couple of pictures of a Bitcoin mining facility I am […]
A few weeks ago I posted a how-to on building a Linux GPU miner for Claymore. Well, at least as of right now, the Optiminer 1.5 Zcash miner is faster than Claymore. I have set up my mining rigs to run both Claymore and Optiminer now. I recommend you run Optiminer 1.5 on Ubuntu Linux. […]
I’ve built some Zcash Linux 6-GPU mining rigs using the Sapphire version of the AMD R9 Fury. I know the AMD RX480 is very efficient, but I feel the R9 Fury is better at mining Zcash. So I’ve been mining Ethereum on my RX480 rigs. One of the nice things about GPU miners is their […]
As you start to build up Bitcoin, you are going to want to think about keeping it secure. There are two main choices – either let someone else protect it for you, or protect it yourself. Unfortunately, when you let someone else take care it, you have counterparty risk, and when you take care of […]
Bitcoin use and value is going to keep growing. It has been around long enough and has enough miners and nodes distributed around the world run by independent people that it is going to stay around for a long time. So it’s probably a worthwhile place to store some of your money. Bitcoin is also […]
Bitcoin is getting all the press, and Bitcoin mining can be profitable. But the equipment is noisy, expensive, and hard to get. If you want to get started in crypto-currency, and have a little bit of technical knowhow, I recommend you build a GPU mining rig first. GPU mining rigs are just as profitable as […]
Every once in a while a hashboard for an Antminer S9 will go bad. I look on the display and it has all XXXX’s on it. Before sending the board back for repair I’ll reboot it just to make sure that as soon as the machine boots up the hash board goes bad. I have […]
