And the reality of Bitcoin is a lot of bad news. The stated purpose of it - as an alternative currency without expensive transaction fees - is really a lot of hooey. It is cheaper to use a credit card, even with 2-5% processing fees, than to accept Bitcoin. The reality is, however, only a few online retailers accept Bitcoin - three to be exact. And while this "currency" is supposed to be a medium of exchange, no one is using it for that, but rather they are merely hoarding it as an "investment".
Well, people doing illegal things might be using it as a medium of transaction. If you got smacked by the Wannncry ransomware, you might have had to send Bitcoin to North Korea to get your hard drive back (shame on you for not backing up!). So that's the fun part about Bitcoin - its links to illegal activity, which governments worldwide will tolerate indefinitely.
The funny thing is, if you Google the word, "Bitcoin" you are treated to page after page of articles about how great Bitcoin is, and no pages about how Bitcoin is a big, huge, bubble. In fact, it arguably is the first Social Media Bubble, driven entirely by conversations in the echo chamber of social media. The people "investing" in Bitcoin are hearing only one side of the story, as any contrary arguments are shouted down. So you see articles like this one, where kids dropped out of college because they made a whopping $15,000 in Bitcoin (now they're set for life!).
