This concept is what drew me to cryptos, and what I perceive as their value. Yet few people even think about it or understand it. When I'm asked what bitcoin is, I typically answer it's a way of paying people without having to give them your account number and liken it to Visa... where they try to increase security by adding a secret pin number to the back which you then have to give to everyone that you make a purchase from. Bitcoin has created a secret pin that never has to be shared yet can be verified. It's an extremely difficult thing to accomplish and that in of itself is immensely valuable.
