It's because most people aren't into crypto for the sake of crypto, they just want the gains and bitcoin among regular folks is driven by FOMO more than anything else. The atmosphere around the sentiment breeds a cult-like mentality where if you're not a maximalist you're a hater. There's not much room for nuanced, well-thought out positions.
So we have created what we have now. Who shouted "BTC is the best investment"? Who shouted that BTC will cost $100k and that it is only for this purpose and needed?
Everyone got what they wanted - almost the death of the idea of cryptocurrency and its transformation into a an investing instrument. And now it's pointless to think that crypto is cool because of idea, and I think that's the end of it.
