Using a Airbitz wallet on an android smart phone, while using Bitpay as a payment processor it is incredibly fast, easy and convenient. I even find it to be superior compared to the other payment options that are available to me. My life and experience serves as a counterfactual to your obviously flawed statements.
I often find that the small blockist perspective is very bearish on Bitcoin, keep telling us how fragile, and unpractical Bitcoin is. I disagree, Bitcoin is great it can do all the things that you say it can not.
No it's not. That's not how it works as this is nothing but anecdotal evidence.
You're simply part of the marginal case of users who like to pretend that novelty = convenience when it's clear the rest of the world (and Bitcoin's largest holders) are not buying the delusion that Bitcoin is somehow superior to other payment systems. At least not yet.
It might be for certain niche use cases (overseas transfers) but for everyday business it can't hold a candle to my VISA card.
It also takes 3 seconds to order diner using my VISA. Moreover I get 2% cash back on everything and it comes with industry leading consumer protection.
Have your parents fully converted to Bitcoin and are they using it everywhere they go now?
If it is so superior to other solutions then why not?
Go online and try buying a full auto M-16 and an ounce of peruvian blue flake cocaine with your Visa card. Report back and tell me how that works out for you.
