My skepticism is not for Bitcoin itself, but blockchain in general. And not blockchain by itself, but actually the marketing hype that blockchain based startups are putting out.

Blockchain is a cool algorithm that can be useful if the situation calls for it. Ethereum is a cool idea that I'm skeptical of, but hey, that's why they're doing it and I'm not. I have my own ongoing bets. But I'm seeing much more of the marketing department using "blockchain" as a catchphrase to turn heads. Specifically the heads that don't actually understand what blockchains are.
