Its technology is obsolete. That doesn't mean it can't still dominate the market share.

For example, a case could be made that coal power is obsolete. There are still plenty of coal power plants on the grid. Windows 8 is obsolete, but you'll find plenty of computers still running it. And so forth. There's inertia in these things.

And Bitcoin's current "dominance" is 60%. That's not exactly an overwhelming position.

So which systems do you see as offering real utility or innovation? Obviously there's etherium

You answered your own question.

Ethereum's not just one token, mind you. There's an ecosystem on Ethereum with a lot of innovation that's not directly rooted in Ethereum's advances. That's the benefit of supporting smart contracts, it's a general purpose computer that other stuff can be run on. There are a lot of layer-2 blockchains running on Ethereum, for example Aztec which has Monero-like privacy built into it.
