I have bought some bitcoin, small amount, to try understand it more so than anything. It reminds me of when I first heard about FB. I thought it was a fad, won't last. Then all these other social media platforms followed, and Twitter in particular etc. There is a lot I don't understand about it, but the digital age is upon us, paper and coin currencies will be affected the same way as the print media is affected by the internet (unless nuclear war starts then who knows what will happen). Paper and coin will be still be around for a while yet but no-one will use them.
