Although there are currently more than 4 million mining equipment operating in the Bitcoin network, the demand for mining machines in the market would be one and a half million more units to add. The increase in difficulty is coupled with the increase in processing power on the network, which has also been touching its maximum historical levels recently. Even, the miners reached the milestone of 100 trillion hashes per second (EH / s) of processing, coinciding with the release of more powerful and efficient mining equipment. Is good to know, the high demand for mining equipment corresponds to the profitability levels that Bitcoin mining activity has shown since its creation, only 10 years ago. 🙄
