I think Bitcoin was not created "to be fun". It can be fun for some cryptographers, economists, libertarians, etc. because it is interesting and ground-breaking for their respective fields. Probably it is not "fun" for most normies, unless they see it as a get-rich-quick scheme, but they won't last a bear market if that's the main reason why they buy it.

"Fun" is overrated, it has become a marketing argument to entice idiots (e.g. Taproot Wizards & shitcoins). It is part of the peak-fiat hedonism we live in. "If it's not fun, it's not worth it". It's a kid-like mindset. Some people need to be always distracted and entertained, just like toddlers, because they are unable to see beyond their noses and face reality.
