You haven't done enough reading, or have been looking at the wrong things. Don't focus so much on crypto and look more at blockchain.
Once you understand blockchain you'll realise that the landscape is about to change. Blockchain is at a similar point to the internet in the 90s. People didn't get why they might need the internet. I mean if you have a phone, TV, magazines and newspapers why would you need the internet?
Once you understand some of the basic principles of blockchain, do some more research in that area and you'll find viable projects which can replace current systems we use everyday. They'll make things faster, cheaper, more efficient, less prone to error etc etc. After you've discovered these projects you have the chance to get it in early and the question turns to "how can I make money from this?" That's where the crypto attached to those projects come into it.
The whole "legitimate medium of exchange" is antiquated thinking. Things have long moved past that.
Yes, I read about blockchain. And yes, I know there are lots of variations on the types of "coin".
Everything your mentioning is at this point "pie-in-the-sky" and huckster talk to sell suckers into being the "Greater Fool".
It could happen, it might happen, but it hasn't happened yet and it might not happen.
Just like those flying cars predicted 60 years ago. We're still waiting on those cars not to mention nuclear fusion.
So, you are speculating on the future. There is nothing wrong with that. You might be the one to get hit by lightning.
Someone has to get hit. Someone has to win the Powerball. Why not you?
