I propose to introduce silver and bronze coins in addition to gold ones. For example, 1 gold - 100 silver, 1 silver - 1000 bronze.
Now in the market there is such a situation when a different popular product has the same price of 1 gold. In this situation, it’s hard to sell something at a cheap price, and there is no desire to spend so much on the current price.
I know that this is not an easy task, therefore this is only a proposal.
