I don't really understand the need to make "crypto" or "web3" the headline of most (any?) product. The concept that "sells" what you're pushing should be its utility or usefulness, not its infrastructure. Tell HN what the thing you're building
does and the community will decide based on those merits. If you're building something to interact with crypto, yea, HN probably doesn't care.
If you're building something cool that uses blockchain in the underlying framework but doesn't require owning/buying/trading crypto, chances of getting attention and traction here is 10x IMO.
