People need to get the "Bitcoin is used for crime" and the "Bitcoin is dead" and the "blockchain is the only useful thing about Bitcoin" out of their heads, and see that the real value in Bitcoin is that you own and control your own money and don't depend on banks.
It's weird how people here assume that everyone wants to be his own bank.
How about being your own plumber? your own butcher? your own garbage man? your own tailor? your own brain surgeon?
Think of the money you'll save! The material of a bespoke Italian suit that cost you 6 grand is probably $200 at most! And if you're your own weaver, that $200 fabric will cost you $50 in thread!
Self-reliance is good character trait to cultivate. To answer your questions.... I do most of my own plumbing. Last Saturday I butchered one of my goats. I cut my garbage service last month (at least until unburnable refuse accumulates and/or wet weather intervenes next winter), my wife and daughters are developing their tailoring skills. I'll admit I'm taking a pass on the brain surgeon thing, though our four kids were all born at home.
In a world where people can't change their own oil or mow their own lawn competently any more, developing good hands-on skills provides many benefits both in life satisfaction and in competency to take on new tasks, whether in your occupation or avocationally. That would apply to banking and investing as well.
