Why is BTC at $6300?

Remember Segway? It was hyped as a path breaking new way to get around. Steve Jobs apparently thought that it was

"as big a deal as the PC"

For all the excitement it generated, Segway was and continues to be a mega flop. No one actually knows what to do with it. No one automatically thinks of it when they consider going from point A to point B.

Bitcoin is like the Segway of currencies. It is cool. It is well designed. It may even be useful in a few niche areas but ultimately, it solves no real problem.

No one HAS TO use it

Even a brand new country launching its own currency has a built-in user base namely the people of that country. Bitcoin doesn't have that luxury.

No one will die if BTC dies

If people stopped caring about BTC and it's value plummeted to 0, nothing of note would be lost except the expensive rigs of big time BTC miners. On the other hand, if the value of country's currency plunged to 0, humanitarian concerns would suggest that help would be sent to that country.

Fast Money Transfer is not (yet) a killer app

BTC has no killer app (yet). Fast money transfer isn't enough of a problem to warrant inventing a whole new currency just to provide easy fungibility.

You could argue that having fast access to cash could improve lives. Moving money extremely quickly and efficiently to exactly the right person is the holy grail of finance so if BTC can achieve that, nothing like it. E.g., if a desperate farmer can get $100 in a few minutes to buy feed for her livestock, it might be the difference between surviving or succumbing to a dire situation. That speed of money transfer is still some ways off.

With all these roadblocks, I'm not sure why BTC is trading at $6300.
