It doesn't matter how many use cases or rationales people give, they are still going to be stuck on the negatives. You'd expect HN to understand that everything has tradeoffs, both pros and cons. Is Bitcoin perfect? No! It needs to improve costs and speed through L2, it needs to find ways to reduce energy consumption and use green energy as much as possible, we need to make sure that the money flowing in things like Tether is legitimate. There's still lots of work to be done and it's still just 12 years into it's existence, so you expect price volatility and lots of hype as people are learning and investing into it.
Bitcoin is successful if enough people agree to believe that it is valuable. And that's the period we're still in now: trying to determine if this thing is valuable and by how much (hence the price volatility).
