You want the moon? Here it is: [0]
If you don't like the BTC maximalists, Etheads, Solanapes or cryptocurrencies in general - avoid.
The same thing goes for crypto twitter in general, but [0] is the equivalent to HN but for cryptocurrencies.
Why wouldn't it be here?
By "crypto," do you mean cryptography? TLS, PKI, and the like?
Or do you mean the scammy stuff that gets downvoted here all the time because it's scammy?
It's hard to find something like this because HN itself is quite cynical/skeptical/critical and the entire crypto space depends on not examining reality all that closely.
On another topic, we've had so so many "HN for $x" threads lately.
