hence, miners do have an incentive to keep it decentralized whilst mining the longest VALID chain, which, by definition means the one that has the more value potential.
so they better not screwing around with some power grabbing fork, else they loose everything...
A short parenthesis about the miners and the market.
What really matters to miners is a market thinking that mining is decentralized, not a really decentralized mining ecosystem.
It's important to remember that most (all ?) available statistics describing the (de)centralization of mining rely on weak (and easy to cheat) heuristics.
