Only selling, not buying has appeared in history. The U.S. legislation stipulates that residents cannot privately store or buy gold, otherwise it is illegal. The government reserves gold, and it is the only legal buyer; individuals are allowed to sell but not to buy. Moreover, the selling price is set by the government at a uniform rate of 35 dollars per ounce, which feels like being robbed by bandits. Today, the price of gold has reached 2,650 dollars per ounce. Furthermore, U.S. laws have long permitted citizens to freely own gold. The wealth of those who bought gold at 35 dollars back then was robbed. What happened with gold will also happen with Bitcoin.
