Sure, right now Bitcoin seems on track to take over the world but I think it’s a mistake to take it for granted. A lot of surprising things can happen over the next 30 years.

Always think critically and never blindly follow the herd.

Well... Number one, a lot of people can't afford to buy 1 whole bitcoin. Number two, I would say, is that the bitcoin rabbit hole will inevitably lead you to learn how to actually take care of your health, so you likely won't need to spend as much on healthcare later on in life.

Take advantage of insurance and your own health and you should be good.

I have a sick feeling (no pun intended) that for a <35 year old today, "health expenses" will be very different, and largely not something that'll be easy to control by oneself.
