Seeing people still argue about the legitimacy of the crypto space, after FTX, after so many hacks and rug pulls gives me more hope for the future of this space than anything else. Actual developments in the space are quite technically dense, so I don't expect to see those discussed in HN.
You seem to suggest that the technology behind cryptocurrencies is too difficult for HN people to understand. While that might be true, it is still not an argument in favor of cryptocurrencies. That something is more complex does not automatically imply that it is more valuable.
