It's amazing to watch the price go up as utility has gone down. In 2012 or so Bitcoin was legitimately useful. Coinbase was around so it was easy to buy. You could move it for reasonable fees / transaction times and it gave you access to Darknet Markets which offered services you couldn't get anywhere else. We also believed it to be private because law enforcement had not yet developed any block chain analysis software. Bitcoin was the only credible coin, everything else was a joke or lacked critical mass.
Now none of that is true. If you're interested in privacy you don't touch BTC with a 10 foot pole. If you want an actually usable currency with speed and low fees you use ETH or any other. And if you're a financial institution you're looking at Ripple. Oh and let's not forget all the BTC forks and exchange hacks.
Yet the price just climbs and climbs, and many people are getting quite rich. I can't say I'm not jealous, but I still won't invest because the fundamentals are all wrong. Someone will be left holding the bag.
