My international bookings, which usually comes from Booking com, have completely dried up ever since the dollar got real strong against foreign currency. 

Alt Currencies should be kept as a back up for Bank instabilities. if You need to close quickly for a Foreclosure or pre forclosure Banks won't be much help of any.

Bit coins are  always a mess to normal people. last day in the cafe somebody told me that Bitcoins are safer than conventional currency notes and soon or later they will replace other currency standards.

Knowledge is the new Currency.

The devaluation of our currency (Inflation) will grow the cash flow - even in normal times at a rate or 3% per year, currently a lot more.

Is your position here also that worker can avoid paying taxes by requesting compensation be paid as property instead of currency? 

Other examples of Private Property rights under attack are when countries impose exchange controls to keep people from taking action to negate the confiscation of their accumulated wealth through rapid inflation; when government imposes ridiculous limits on individuals right to improve their real property; when restrictions are placed on assets individuals can own (it was illegal in the US to own gold bullion until our currency was no longer backed by gold); and when taxes are imposed on wealth for the purpose of redistributing that wealth.  

We are in the Middle East not take over oil but to control what currency oil is bought it.

Printing currency recklessly always results in the same outcome...

However, if I had just come into a significant amount of cash, I would be very nervous about putting it into crypto currencies or syndications.
