I do agree that a system that used less energy would be better. When it's available, and widely enough accepted, I'll switch.

> And about anonymity. Yes, Bitcoin itself is not at all anonymous. Everything's in the public blockchain. But one can use mixing services, through Tor, and get different Bitcoin. Which aren't linked to the starting Bitcoin, or to any identity or IPv4 address that's linked to the user in meatspace. Maybe it's not perfect, but it's good enough for me.
So yes, usably anonymous.
Wait, you're saying they're criminals? I wonder why the bitcoin guys aren't.
People hurting others (what's criminal to me) will use any system that's secure, hidden, anonymous, etc. Tor is a good example. But in a sense, they serve as canaries for other users.
There are techniques to try to find that out, but they're not infallible.
