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.
True. Rich people also gamble with their bitcoins because it’s now the trend these days if you are playing in crypto casinos online. So aside from investment, bitcoin too is also profitable when used in gambling. But knowing that bitcoin value will still go far and has the chances to make it to its all time high, then I prefer to hold bitcoin and benefit huge profits in the future.
