If the president were to issue new currency, would you still dare to buy it?

Presidents have begun to wreak havoc on the currency circle. Seeing Trump making a lot of money, everyone wants to issue a coin to harvest. This unreliable Trump has made the world chaotic, and the currency circle has been filled with complaints. In the end, it is still the global small retail investors who bear everything. How should we face the current market fluctuations in the currency circle?
In the currency circle for a day, it feels like ten years in the mortal world, not a bit wrong. The savings of ten years can be emptied in just one day in the currency circle. It's really true that once you enter the currency circle, it's as deep as the sea, and from then on, the wallet is just a passerby!!!
