> No one uses crypto outside of speculation.
Same old argument while closing your eyes to actual use cases. You have this technology where - leaving aside free cross-border trustless payments to anyone, you can have an immutable record of data to store, unhackable, solves spam and you actually still think this is all about speculation? You're on Hacker News, really recommend putting on your hacker hat and re-evaluating it.

On a slightly different note, Opensea is not a true dApp and it's a little centralized in places. But yes of course NFTs right now are extremely speculative. Look elsewhere, ENS domains usage is at an all time high and rapidly growing (even after the recent price correction), Uniswap recently crossed a trillion $ in total transaction volume in its lifetime.
Blockchain tech is an extremely powerful tool, it's a shame most hackers on HN are hostile to it which makes them miss real use-cases happening under the surface.
