We'll be back here in four years when bitcoin is well above 100k being used happily as a store of value by millions of people and someone like you will say the exact same thing again. How long will it take you to realise that it's already a success?
at $DAY $COIN is at $MAX_PRICE. it never reaches $MAX_PRICE ever again. for someone who bought at $MAX_PRICE, what is the value they received?
It's ironic, the same thing that makes these coins valuable to people (volatility, and mostly in the upwards direction) is a major reason why they are hard to use for mass transactions.
However, there is some good here. People are getting familiar with crypto by participating in this investment strategy. A relatively stable coin capable of high transaction throughput and low fees - one that can actually be used as a currency instead of an investment - will benefit from this in the future.
