How many words are you able to use in their proper context but when pressed for a dictionary definition of the word you often fail to properly define it?
Most people I have talked with about bitcoin seem to have this
"passive vocabulary" when it comes to money and currency.
People know how to use currency so they think they can define money yet do not know how to define the difference.
Next time you talk with someone about bitcoin challenge them to see if they can define currency or money. If they confused the definitions then that will be a great opportunity to explain the difference and get them on better terms to understand Bitcoin.
