I don't "hate" bitcoin and I'm certainly not going to down vote someone who wants to have a discussion. For me, personally, I can't see a single transactional issue that the new "coins" solve that your 70 year old father's financial systems don't. Rather, in my opinion "coins" re-introduce problems that have been solved in banking and finance for more than a century. Transactionally, they seem like a hassle. With respect to investing, they smell like a pyramid scheme. I think there is no coincidence that the "coin" landscape is littered with failed charlatans and corrupt exchanges. I view "coins" and "Tesla" stock as interesting day trader entertainment. As a way to test if I am smarter and faster than the system. I would never consider either as anything other than speculative entertainment and would never base a portfolio or retirement on them. That is just my opinion though and if you think that "coins" are great then power to you.
