I had two clients from America I want offer graphics designing jobs for, I demanded my payment would be in BitcoinBTC or Ethereum. To my greatest dismay, they were dumfounded on what Bitcoin or Ethereum is. I am still suprised up to this very moment. 
That sounds hilarious but saying Americans is just an understatement, as a bigger part of the global have never heard of Bitcoin, let alone knowing its functions and benefits to the global economy. Awareness needs to be created for the global recognition of Bitcoin to take place.
