That’s how it goes with all security vulnerabilities. IMHO sunlight is the best disinfectant for stuff like this. But yeah, it can cause some chaos.

Well with other currencies you sort of have a nation state behind it, backing its value. Failing that, that nations armed services :-)

I don’t get crypto… is there any coin that’s actually usable as, you know, currency?

From what I can gather, none of them scale so each transaction is slooooow and expensive.

The coins themselves carry no value and is backed by jack-shit. Comparing them to baseball cards seems very apt. Baseball cards, bubbles and FOMO.
