Answering a question from a group member: With the end of the year approaching, should I withdraw my funds for the holidays, or keep them in @cz_binance's USD1 wealth management product with a 20% annualized return? This question actually needs to be broken down: I have USD. If the RMB continues to appreciate, is now a good time to convert my USD into RMB? If denominated in RMB, to what extent would my USD wealth management product need to cover the depreciation of the USD against the RMB? Based on this question, a group member shared their thoughts on the lost 30 years caused by the appreciation of the Japanese yen. This issue is very systematic. Individualists are easily misled by marketing accounts claiming that Japan's lost 30 years were caused by the yen's appreciation. The correct definition is that the rapid appreciation of the yen was mismatched with Japan's economic transformation. Currency appreciation – stronger purchasing power – corresponds to a consumption-driven economy. Back then, Japan, like us, was an export-oriented economy. The yen's appreciation led to a rapid appreciation of yen-denominated assets. The released funds quickly flowed into the stock market and then overseas, rendering Japan's consumption transformation meaningless. Currently, the RMB is largely within a controllable range. Appreciation equates to stronger purchasing power. Even with a trade surplus, a healthy transformation towards a consumption-driven economy involves using produced goods to absorb the surplus purchasing power. Given the current controllable RMB appreciation, what will the appreciation margin be this year? 4%. It's highly likely that appreciation will remain within the 4% range next year, until the domestic economic cycle shifts away from a traditional economic model. In summary: If your savings on exchanges or in wealth management products don't exceed 4% annually, it will be difficult to offset the depreciation of your USD. Given the current market's lack of trading, Binance's USD1 annualized return is quite high, but the limited quota of only 50,000 makes the wear and tear on USD1/USD negligible.
