Instead of connecting to a standard PC or laptop, the USB Bitcoin miner setup could also be connected to other smaller, low-cost computer devices like Raspberry Pi, which offered suitable capacity to run the miners at the time. Such a computer is called an ASIC. For comparison, some USB miners claim a hashrate of 25 gigahashes per second, which is 25 billion hash calculations every second. USB Bitcoin miners do not have the computational capacity to effectively mine or even generate any profit as of November , so they are not worth it if you want to mine for income. Key Takeaways Bitcoin mining requires a lot of computational power, as your hardware is required to generate trillions of hashes per second.
