I don’t know if BTC fully fixes this, but I agree that crypto in general is heading down the path that will likely fix this. And agreed, HN continues to hate crypto due to 99% of it being garbage, and ignoring the 1% that is actually revolutionary.
Because you are familiar with fiat/cash and its risks and you use crypto only for "crypto" stuff not to buy your groceries.
You won't send cash to someone you don't really trust, would you? How is crypto different? With paypal you get some "security" with the tradeoff that sometimes you won't get it(i.e you get scammed either as buyer or seller) and many times it just pissesoff both the sender and receiver using "fraud detection" and treating both as criminals.
