In the future, domestic foreign exchange will become increasingly tight, and Bitcoin will become more and more popular. So it is better to plan Bitcoin early, especially leading currencies such as BTC, ETH and SOL, and hold them for a long time.
Brazil has no foreign exchange at all, and it has no money to repay the $80 billion debt owed to us. So it can only accept RMB settlement, but even if they use Brazilian real to exchange our RMB, they are taking a huge advantage. Some people actually think that we can use the exchanged Brazilian currency to buy iron ore and agricultural products. Those resource companies are controlled by European and American companies. The RMB we exchanged is hard currency, what is the use of the real we exchanged back? Don't waste our foreign exchange anymore.
