Small price to pay since SBF had been wanting to buy-out the CME just prior to the collapse.
As has been stated before... this would have caused 'biblical devastation'.

Lol, CME is a 63 billion-dollar public company! Where the hell was he ever going to get that kind of cash, and did he really think he would convince the shareholders to a buy-out?
Duffy stated it in an interview I recall. lol what a fucking joke that would have been.
as for the rate increase, eh, who cares? go make more money. could we have it any worse, really? come into desk each day, click mouse and type on keyboard, win. really? it's so bad?
Personally, I dun give a shit. 3-4 cent higher execution fee? Just set your profit target 1 tick higher, problem eliminated.
