Anyone getting a controlling share of the network sends it towards zero… the next step of that scenario comes with a fork and a huge sell off of the controlled asset. Mutually assured destruction.

Fractional shitcoins kill transaction demand so reducing the value of the assets they control long term, which includes both utxos and miners.

Where I see Bitcoin as beautiful is it has all these paradoxes where total control ultimately hurts the one who would invest in that goal. It forces coordination and distribution in so many ways.
