In about 41 years, a decentralized currency will emerge, and its stability will replace legal tender, and the global currency will be unified. Governments will lose all their ruling rights due to the loss of monetary ruling power, and national boundaries will gradually blur. World trade and productivity will enter a new high-efficiency state. The increasingly developed Internet will eliminate most jobs such as middlemen and intermediaries, and people will only need to pay a small amount of physical or mental labor to get more value. Working hours will be reduced to more than half, and the crime rate will also decrease.
