<p>The correct answer is yes, they can. And the claims about falling value in that scenario are borderline illiterate. Imagine they rise the fees, and you hold all your savings in BTC.

Good point that miners are anonymous. I hadn't thought of that.

<p>Could miners with enough mining powers (say >95% of all blocks) form a cartel where they demand absurdly high transaction fees? Of course, I still could could hope for a miner not in that cartel to relay my transaction for a lower fee, but in that case I couldn't be sure <em>when</em> my transaction gets paid to the adressee.</p>

<p>Is this a plausible scenario?</p>

(Asked by: username_0 on 2013-04-05)

Could miners with enough mining powers (say >95% of all blocks) form a cartel where they demand absurdly high transaction fees? Of course, I still could could hope for a miner not in that cartel to relay my transaction for a lower fee, but in that case I couldn't be sure *when* my transaction gets paid to the adressee.

Is this a plausible scenario?

Cartels are unstable due to members defecting for the economic benefit that comes from doing so.

See the [Prisoner's dilemma](http://en.wikipedia.org/wiki/Prisoner%27s_dilemma).

Because miners are anonymous, the cartel would likely see defection immediately.
