A real hacker would recognize these are the early days of a new technology with incredible potential. Its tech is disruptive enough to already grow a marketcap measured in billions, I don't know what is gained from harping on all the early failures.
The distributed ledger isn't what people are making fun of - it's the frantic rush and chaos around using it that is ridiculed, and in many cases, rightfully so.
Edited additional thought: Come to think of it, I don't think a lot of the new found SV culture is really as hackerish as it's made out to be - it's the same business stuff that cyberpunks in stories would snub their noses at and work to undermine, except it's masquerading as hacker culture - there's a very cool protocol underneath bit coin that probably will fundamentally change how we do "something" in the future. But what is everyone climbing over themselves about with Bitcoin? Get-rich-quick after get-rich-quick schemes and ridiculous business enterprises.
Silk road I got - buy whatever with crypto-currency, hard to trace, from hard to find sites on TOR, and a package arrives or a service is done. Cool! But that's not what the clamoring is about now, and it hasn't been for ages.
That's not a hackerish interest, that's business people playing with yet another asset to trade.
Avoiding them in the future, perhaps? I wouldn't mock a mature technology for historical teething issues, that's pointless. But cryptocurrencies keep replaying the same errors and conflicts without seeming to learn a thing. I like the idea of cryptocurrency, but it's not going to succeed unless we learn from the (myriad, severe) mistakes of the past.
