It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

However, it took bitmainland only four years to achieve such a high profit in one year, while NVIDIA spent 24 yearsbitmainland's operating profit may exceed US $3 billion
according to the conservative expectations of 75% gross profit margin and 65% operating profit margin, bitmainland's operating profit in 2017 is US $3 billion to US $4 billion, while NVIDIA's operating profit in the same period is US $3 billion.
