Surely, my list isn’t complete. You can always add a comment and present more facts.
There's one you didn't add about what people are doing with bitcoins asides just hodling, people who gamble online on casinos that do no have a direct funding option via their fiat bank account, fund their account via crypto using their bitcoins to fund their online casino accounts so they can continue gambling there.
That's also possible as bitcoin can be used to finance in casinos and change it to fiat. But if you're into crypto gambling then there's no need to convert it to fiat. However, bitcoin can be a good retirement gift since its value will definitely grow in time. Or bitcoin can be used simply as an investment for long term hodling since that will also ensure large profits ahead.
The people who have urged him to buy bitcoin tell them that this is the investment of his life, and I am not lying to them, just talk to them about how it works and how the world goes in the direction of digital money and they like it when I tell them that they can manage their money as they please, they don't have to go to banks or anything, they can manage the amount they want and they can buy if they want 1 dollar in bitcoin.
The ones that are more difficult are the older people, some of them don't have so much order and they don't know much about computers and they don't use the internet, but for everything there is a solution, I told them that they can buy and keep their bitcoin in a piece of paper that is considered a wallet with your public and private key, I talked to you about trezor and more, I haven't been able to talk to all of them, but what I tell you the most is that the greatest utility you have is how to save.
