Bitcoin mining machine manufacturer Canaan (嘉楠科技) officially launched two latest home mining devices yesterday (8th) —— the Avalon Mini 3 heater and the upgraded product Avalon Nano 3S of Avalon Nano 3. What are the highlights? (Background: Mining machines transformed into heaters! Canaan announces the launch of home Bitcoin mining machines: Everyone can be a miner) (Additional background: Canaan｜Another mining company enters Kazakhstan! Canaan operates its own mining machines locally, closely following Bitmain and BTC.com) Bitcoin mining machine manufacturer Canaan (嘉楠科技) founder and CEO N.G. Zhang stated in an interview last November that in order to promote the development and popularization of the cryptocurrency mining industry, they would launch home mini mining devices that meet home needs while also helping users participate in mining activities. Just yesterday (8th), Canaan launched two latest home mining devices that double as heaters at the Consumer Electronics Show (CES) in the United States —— Avalon Mini 3 (with stronger power and heating effect) and Avalon Nano 3S, the upgraded product of Avalon Nano 3. What are Avalon Mini 3 and Avalon Nano 3S? Avalon Mini 3 is the main new product launched by Canaan this time, with the following specifications according to the official website: Home heater, can achieve full-house heating in 10 minutes; Power of 800 watts; Equipped with 66 pieces of 4nm computing chips, computing power reaching 37.5TH/s; Comes with an LED screen that automatically adjusts light sensitivity, supporting custom images and animations; Focused on practicality, it provides Bitcoin mining while maintaining a silent mode; Smart operation, just use the Avalon Family App to connect the device, Avalon Mini 3 can connect to the preset F2Pool mining pool for mining in the settings, and various function adjustments can also be operated on the Avalon Family App. Currently, both Avalon Mini 3 and Avalon Nano 3S are available for purchase on Canaan's official website, priced at $899 and $249 respectively. Avalon Nano 3S is the upgraded version of Canaan's previously launched portable small heater Avalon Nano 3, with a computing power of 6TH/s, featuring low power consumption and portability, but with lower computing power. How much can Taiwanese households earn using Avalon Mini 3? Since mining requires setting up wallets, mining pools, and other configurations, the author speculates based on official explanations that Canaan should have already linked to the F2Pool mining pool and will help consumers convert the Bitcoins earned into cash rewards. Canaan's official website provides a simple calculation tool to estimate how much cash rewards can be earned. Here, we will do a simple estimate: If we take the average monthly electricity consumption of a typical household to be around 300 kWh, plus using Avalon Mini 3 for 8 hours a day, the additional electricity consumption for a month would be approximately 800 × 8 × 30 = 192 kWh. According to Taiwan Power Company’s current residential electricity costs, the average electricity bill for 331 – 500 kWh is about 3.61 NTD (about 0.11 USD). According to Canaan's official website calculations, the cost of running Avalon Mini 3 in this way for a month is about $63.36, while the monthly return is about $61.37, which can almost cover the electricity costs for using the device. However, this data also needs to consider the Bitcoin price at the time of sale, and the overall BTC mining computing power continues to rise. Over time, it may not be possible to maintain such high returns, which requires further verification.
