Financial predators like this best. They go in first to add fuel to the fire, hold assets, then short your currency in the foreign exchange market, and then sell it in large quantities at the limit. Let the country's currency collapse and let the country's foreign exchange reserves and other excellent assets be looted.
If a country is really confident and not afraid of changing its currency once every three to five years, its financial system will be completely changed, and society will return to the stage of barter. If the government does not step down and the people do not rebel, it is really feasible, and some countries will be hacked if they play well.
At present, North Korea is the only country on earth that dares to play like this. This is why North Korea is called a rogue country, and few ordinary businessmen dare to do business with North Korea.
