At the moment, there isn't a single alternative product for a state-free currency as a store of value that has reached the valuation of Bitcoin.
I'm not even a Bitcoiner, but if this isn't proof to you at this point, nothing will satisfy you. The proof doesn't have to convince you it's the future of currency, but it should certainly statisfy the question of "how has blockchain enabled anything new and interesting?".
The truth is, blockchain is less of a technological innovation than it is an organizational one. It is technology that attempts to digitize human organizational patterns as opposed to simply analog processes.
Those selling crypto to the moon and profiting off of the hype certainly ruin it for everyone. The promises, the lies, the failure to deliver is certainly an issue to take up. At the same time, there is quite a bit behind the lies that is worth looking at.
