Cash is eroded away by inflation. If your currency hits high inflation for years continuously, like we had in Iceland (yes, I&#x27;m from there), going up to 25%, your cash isn&#x27;t worth shit in 5 years time.<p>I&#x27;ve experienced that. My parents experienced that. They had no &quot;investments&quot;, kept their money in low-interest savings accounts, yet somehow their life savings was no longer enough to buy a used Toyota.<p>Want to get more strange? What about war? How much is your money worth in case WW3 breaks out? 
Hardly likely? sure. Is it possible? absolutely.<p>The point is, nothing is &quot;safe&quot;, just different levels of risky.
