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.
Right, bitcoin is a technology, a revolution that could change the world's financial system, so there cannot be only a few words to describe how amazing it is. With the era of technology development, everything is available online, and in my opinion, the best way is for everyone to learn on it, very easy to understand and more complete. If someone really wants to learn about bitcoin, advise them to spend a lot of time on bitcoin, we gave them a chance, it's up to them to take it or not.
