We all know what our currency (1$, 1€) means. We don&#39;t have to think about it. BTC has not achieved this yet. See the talk, it&#39;s amazing: https://www.youtube.com/watch?v=pD3Uawu2JMQ&#xA;&#xA;But this has a flipside.  &#xA;&#xA;Level 1: &#34;EUR in 2010&#34; and &#34;EUR in 2025&#34; are very different currencies. Looks the same, same pictures, same unicode character (€), very different purchasing power.&#xA;&#xA;Level 2: No, you can&#39;t multiply the 2010 prices with CPI over the years. 1000€ in 2010 would be 1368€ today according to these statistics. But that&#39;s completely wrong and we know that. They CPI is not calculated very well.&#xA;&#xA;Level 3: Even if we got the &#34;purchasing power level&#34; right, the relative prices have changed. In 2010 I could not even get some things (like click in an app and someone would deliver me youghurt to my doorstep 30 mins later). A laptop that cost 1000€ in 2010 is basically a free gift today, or less than 100€. The relative prices are changing as well.</html></oembed>
