Normally, and IMO, they would be forced to raise the ask to entice sellers. Simple. If the ask were where it really should be .. say ... .0038 ~ .005 ... ish .. we would have volume.
But MMs cannot stand to lose, .. to the point where they routinely step outside the provisions, guidelines, operating standards, and indeed the law as a measure of last resort.
Often stepping outside the law is always profitable. Lets face it .. if you can make 32 million breaking the law using shady and unethical tactics .. in a week or a month .. who really cares about the 5m dollar fine that you MIGHT get ???
Just the cost of doing (dirty) business. ...
<sarcasm> its all our own fault after all, making them fill orders and all that .. for shares they dont have .. LOL </sarcasm>
