What are the most effective crypto USB miners available right now? I’m interested in understanding their performance, efficiency, and potential profitability.
Solo mining is the only way to make it worth your while. Joining a mining pool won’t earn you anything—literally nothing, not even a cent in six months. It’s like buying a lottery ticket and hoping for a minuscule chance of finding a block on your own.
These miners are good for learning the basics, like setting up your pool and wallet, but they aren’t very profitable. Miners with under 100TH or high electricity costs (over 8-10 cents per kWh) usually don’t offer a good return on investment (ROI) or recover your initial costs quickly. For small, home-based setups, you might consider options like FutureBit Apollo miners (which can host a full node on some models), OpenSource Bitcoin miners like Bitaxe (which is pricey at around $140 for a 5-600Gh miner), or even the new Canaan Avalon Nano 3 available on Indiegogo (which might not be profitable quickly but offers good value if it proves reliable).
If you’re just starting out and don’t mind low profitability or high electricity rates, you can use the heat from the miners to offset some costs. In my experience, with high electricity rates, the cost of mining versus buying heating oil was almost equal. You could also use mining as a business expense, writing off depreciation and electricity costs, or take a loss on the mined coins to reduce your overall tax bill if you have other business income.
Are these miners good for learning? Yes. Are they worth buying for profit? No.
Just my two cents from a bit of experience in mining.
a hash rate of approximately 75KH/s with low power consumption, making it an affordable entry-level option for beginners at around $34.99. Another solid choice is the Compac F, which provides a higher hash rate of 300GH/s for about $220, suitable for those looking for better performance without a significant investment. For more serious miners, the NerdMiner V3 boasts a hash rate of 78KH/s and is priced at $45, featuring Wi-Fi connectivity. These USB miners are compact, easy to use, and can be plugged into any USB port, making them ideal for casual mining or as a supplementary income source, though their profitability will heavily depend on electricity costs and current cryptocurrency prices
I purchased one and ran it for 6 days. My highest share difficulty was 6.53, while the Bitcoin blockchain difficulty is 70,343,519,904,866.8, just to give you an idea. I got it for fun, especially since you’re still trying your luck with the lottery for a week.
