I have lived in Soviet Union. In the end of SU I even as a 13 year old child bought USD, and earned money from that, when changed back after months.

The same was done after getting independence. You bought Finnish marks bought USD or German marks and after few months changed back, because the economie of Finland didn’t had best days in the 90’s and USD rose in value.

You literally make money with that.
