Potential is great, but so is the risk. For example consider this: apartments in Kiev are now priced at about 50% of their usual price, you may buy one. Now hypothetical scenario: in the Spring there is an Russian offensive on Kiev and your investment is destroyed, you have $0 in that case.
I think investing and war are very very bad companions. If you want to _invest_ your cash you should avoid too risky moves.
On the other hand if you want to _speculate_ then go ahead, but be prepared to lose 100% of money for maybe 200% gain (for my example with real estate).
