You know why? because bitcoin is the face of blockchain so technically using bitcoin is using blockchain which I really admire to see when the mass is using it. I've been in a crypto startup/meeting once and what they first introduced was the blockchain coz it is the heart of the project and is necessary. Teaching how to fish is indifferent to educating what to fish.
I can understand it, because it's easier to tell people about bitcoin rather than explain what blockchain is.
Good analogy, I respect your POV. But for me, blockchain more like fishing in that analogy.
Money is a sensitive thing for people. The formula for most conservative people is money+internet=scam.
We should use different way to introduce cryptocurrency or blockchain I think.
With the wide cover of internet and technology, it seems like research is the most powerful weapon now towards ignorance and scams. It's 2020 already, a decade with bitcoin, cryptocurrencies became common with our generation and almost every one who have access to the internet knows what crypto is and what it does.
In my country (Indonesia), Internet = Social Media. They make sh*t gone viral almost everyday.
You can check how Instagram, facebook, and youtube full of Indonesian.
They dont have time to research or even read.
