Agreed. And adopting this kind of new platform involves a learning process / curve, which inevitably takes time and increased exposure.
Back in 1993, my friend showed me "the internet," which was basically a few chat forums. My first thought was that this "internet" thing was not for me, and that I'd never waste my time using it. Three years later, I was online, sending email, and finding the net very useful, for personal communication and as a resource. Of course, that was only the beginning.
When I tell friends about cryptos ( or even gold / silver), I get the type of reaction that I gave my friend in 1993. Aforementioned friend even reacted thus when I told her to buy bitcoin. But I realize that they are not ready for it ... not YET ready.
The only thing we can do is try to pique their interest, slowly if need be, so that they will be ready someday. Hopefully not too late.
Interesting note. Back in 1985 (yes, I was on the planet then), my same friend had excitedly told me, "Hey, on the 4th floor of the university library, they've installed a few personal computers. Go check them out!" My response was ... "I've got a typewriter that works. Why would I need a computer?"
Moral of the story: Even stupid, hopeless people can learn new and important things and change their lives for the better.
Ever onwards and upwards.
