There is no easiest way to explain Bitcoin to any person other than telling the truth and the importance of Bitcoin. They'll never appreciate the value and role of Bitcoin to them if they won't clearly understand it that is why we shouldn't hurry to teach them but rather do it step by step until we reach the goal. Because Bitcoin is not just a few words or a simple discussion but indeed, it was a long discussion which means that it takes time for the listeners to catch up. especially when we are mentioning some technical terms.
