You'd have to spend $30M per day in order to control 51% of XMR, and then you'd YOLO your life savings (which would have to be another couple hundred million dollars) on centralized exchanges without anyone noticing?

I meant I, as someone that is aware of attempt to take over, not as an attacker.

It's only doxxing if you can, you connect that large transaction to the attacker, but you can't unless I'm missing something.
