The Avalon Nano 3 USB Miner:



  • Algorithm: SHA256 (Coins Mined: Bitcoin, BitcoinCash, etc.)
  • Hashrate: 3.6 GH/s
  • Chip: 40 nm Avalon A3233 Chip
  • Power use: Under 5 Watts

The Review:

The Avalon Nano 3 is a USB miner built with a 40nm Avalon A3233 Chip, capable of mining the SHA256 algorithm at about 3.6 GH/s. The miner is now outdated, and although it uses very little power, it can only mine about $0.20 US per year provided you do not pay pool fees or electricity fees. The Nano 3 is completely silent, but as it has no fan, it can get extremely hot. I personally recommend plugging the USB miner into a powered external USB hub, and also circulate the air around the miner using a fan.

I personally had one of these units, and it was actually able to mine at close to 3.9 GH/s. Some later Avalon Nano 3 devices could reportedly even hash at about 5GH/s according to users on forums such as BitcoinTalk and Reddit. Unfortunately, my device stopped working several years into mining. While it can work with Windows, Linux, and most instances of Mac, I personally found it a little harder to set up on the Raspberry Pi (which runs Linux) than other USB miner such as the Gekkoscience 2PAC and the Moonlander 2. 

The USB was as cheap as 15-25 US dollars per unit at one point, and can now be found on online retailers such as eBay and Amazon, though it's significantly more expensive now. This device is not recommended for anyone who wants to make a profit from cryptocurrency, but is a decent choice if you want to learn the basics of mining, or if you want to get a gift for a friend or family member with an interest in cryptocurrency. Although a few years ago, this miner could make several dollars a month, today, it's little more than a novelty item and a little piece of cryptocurrency history. 



I am not in any way affiliated with Avalon or any other crypto/crypto-related company. I personally have a green Avalon Nano 3 initially purchased from HolyBitcoin for about 25 dollars. It worked for about 2-3 years before it stopped hashing. I did not try to repair it, and instead put it into a box with other dead miners, USBs, and other broken tech.

Remember, investments in cryptocurrencies are like any other investment: Invest only what you can afford to lose. No investment is a guarantee.
