Dead spies hurry to roll, mining is certainly not a lifetime profit, when Bitcoin is lower than the cost of electricity is not suitable for mining, if Bitcoin is above 6000. Still profitable. At the current price. If more than 7,000 mining machines are in operation. At least 4% of profits per month, 48% per year, is still a good investment target. Is there a bank? 2% per year? . The white paper says that when the btc price comes to 14000, there will be a monthly dividend of more than 100%. There are no more than 7,000 caves. Do you have to dig a cave again? Power companies provide warehousing for free. This is a very good suggestion. If you are interested in IRM. Welcome to invest. But if you don't agree. Please sell rock2. Get out of the way quickly.
