Fellows, I've been trying to find a good way to explain Bitcoin's functioning logic to people that are not familiarized with this technology, and I'd like to hear from you guys: if you had the task of explaining BTC to someone, what concepts would you highlight the most?

I will highlight the fiat inflation compared to Bitcoin. I also emphasize the government and the banks that controls our transaction everytime we send or receive the money. I also tell them that your money is controlled by banks and not by them when they put their money in the bank.
