Question: Why do bitcoin fans care about a cashless society? That's basically what bitcoin is. No paper, no metal coins. Yes, that's what we're moving toward, but I think most people are happy not carrying around cash. Yeah, the government is pushing toward this but I don't see much opposition to it, except for frigging ZERO HEDGE idiots. Why do people still read that crap? All they want to do is push precious metals--the people who write the articles probably have an ulterior motive, you know.
Having said all that, I am definitely a fan of coins and precious metals. But as far as money goes, it really, really doesn't need to exist physically. Just like you don't need a stock certificate when you own a stock.
I would argue that Bitcoin (and Monero to a greater extent because it is private) is analogous to digital cash. You can move cash around without necessarily having to go through a bank for quite some time. Same with cryptocurrency. Banning cash means they want control of every transaction. If a government moves to ban or restrict cash, they will also move to ban or restrict its digital equivalent.
But let's say none of that is correct. Even then, we should let our representatives know that this is a short step away from tyranny and it must not be allowed.
Yes, we can speculate the worst situations if the EU decide move to cashless society, the used of their own official digital currency should be affected bitcoin as well. How? I don't think they will allow another competitor which has more advantages. People will prefer to choose bitcoin obviously, if they don't like their every transaction being tracked.
However, I don't think EU citizens will approve this, they have right to vote? It won't be running smoothly without a hitch.
