Merry Christmas dear mates! First of all I'm glad to congratulate you with this great holiday!
And now let's move to the main topic of my post. I think it is important theme to many people among of us I mean what presents to prepare to friends and relatives. And I think it not should be just thing which will be forgotten after couple weeks but thing which can be useful and bring joy to life of my closer ones.
I spent enough time trying to decide what to do and here I found one thing which will be useful to my crypto friends. And I found Nerd lucky miner. It's a solo miner it is a free and open source project that let you try to reach a bitcoin block with a small piece of hardware.
Officially Nerd miner T-190 supports 117Kh/s but according to my info after upgrade of softwear it can reach higher numbers. By the way to upgrade it you need just Windows or Mac laptop and usb-c wire. To upgrade software takes just nearly 1-2 minutes. This miner supports low difficulty share pools like public-pool.io where also you can check your stats like it shown on picture bellow.
Also you can find more information about this miners series on GitHub official page
As you can understand with such small difficulty to solve the block it is on your luck and even more lottery.
But couple months ago lucky guy could to do it and got 3.5BTC at once.
As so as I have problems with buying on Amazon or Ebay I decided to buy it on Aliexpress. With discount it cost me nearly 23$ for one item with free shipping to my region.
Parcel arrived to me after 10 days when I ordered 5 items for my friends. They were packaged in plastic box with connection wires with which you can connect Nerd miner to Raspberry Pi or it to each other several items and make from them small mining farm.
Also in box was additional radiator for processor and cheat sheet with quick guide how to set up it.
To connect this device to network just enough wi-fi router. Also it's worth to mention that with ths device you can try to mine not only BTC but also some other coins.
I hope that this idea of gifts will deserve your attention. And in my opinion this miner can become nice gift for crypto geeks and funs.
So that's all for now! Stay tuned! Yours
