If it sounded reassuring to you then I should work on my writing skills, it certainly wasn't meant that way.

Absolutely, if you have funds in this - and any other unaudited - exchange GTFO or you may lose everything. Either their claim that they have the funds is real and you get your money and later you can re-deposit it or you'll be at least not one of the ones left holding the bag.
I read it as a mid-tier accounting firm selling their seal of approval to raise income on sketchy accounts. That's not really news (or effective) unless the accounting firm has some respectability (like Aurthur Anderson ;^).
I've been in the financial services world since 2007 and have come across Mazars about as often as I've seen work from the big 4, they're simply a bit lower on the totem pole image wise but their non-crypto departments deliver pretty solid work.
The big differentiators are the price point and their ability to create an army of consultants on a moments notice where required. The big four clearly have an edge in those cases - at a price.
If Mazars is heading out the door you should try to beat them to the curb.

sounds like a reason to leave the mine (i.e. there's something really wrong and this is a warning sign).
