I don't understand why people are so obsessed with the 12% APR. If they had the money to run the most profitable signature campaign, leave $40k as collateral, charged absolutely zero for mixing, and carried a shitload amount of money to begin with as we saw, then it doesn't preclude the possibility that they wanted to attract users via APR.
That's a bit extreme. More like you'd just get paid less to advertise more legitimate campaigns.
I'm yet to understand how is this legitimacy measured. Presenting yourself as the superior custodial mixer, about to introduce blinded bearer certificates, backed by significant collateral, and employing one of the most reliable campaign managers, had successfully and convincingly passed my test of legitimacy.
