Trust me! Money is just toilet paper if it doesn't have any product value to represent. I remember a country's leader who tried to overcome an economic crisis by printing as much money as possible. The sad truth is, a country's economy will improve if there is a balanced cycle of production, consumption, exports, and imports.
Humans in my world don't yet know paper money... they still use silver and gold coins as a means of transaction, where silver and gold inherently have product value. So, don't worry about your coins ending up as rusty metal. Lol
I use crimson coins. I have unlimited supply, but I don't give them out. I use fake scarcity to inflate their value.
