Aside from being the most precious, non-renewable resource, time is our universal currency.

It makes sence for South Africans to invest in a stronger currency in a safe vehicle like property.

Many of my tenants in my C class buildings have never had a checking account, and one very nice retiree (who pays like clock work) is doing all his business at the local currency exchange. 

.- Bonds seem like a bad bet as an investment with interest rates seem poised to increase for the forseable future- Cash seems like a poor choice, with inflation currently high and I believe likely to continue- Cryptocurrency is super volatile and while everyone has a great argument for this currency vs the other one, it seems like anybody's guess as to which coins will actually be widely adopted long-term- Gold and commodities, like energy, seem interesting and like they might do well with challenges in the supply chain and inflation looming.  

Currency conversions and getting money over here from other countries does matter as it affects yield.The U.S. dollar has strengthened and the Yuan has started to get weaker.

Besides the obvious Real Estate Markets I was wondering about currencies, diplomatic relations, things of that nature.

Time is the real currency. 

With the oil soaked Loonie reaching a 9-year low against the USD and other marker currencies this month, the Canadian economy is stalled and may even be heading for a bit of a recession.  

I have posted else where that a major market crash could happen anytime if there is a currency crisis.

Unless the goal is a complete capitulation of the currencies..
