Sorry for the late reply. Short answer is I don't "know" anything. I just think there is enough smoke that there might be a fire too. If some of the speculation out there is true, it is a huge problem waiting to happen. In contrast, bitUSD is absolutely backed with a minimum of 2:1 collateral, through a smart contract, and is an effective (accurate) peg to the $ (they also have bitCNY, and others too). I would love to see wider adoption, or else just greater volume on the Bitshares DEX. I do think that is a matter of time.
In terms of other safe havens...I would have suggested DASH because it seems to me it did better in the last couple of corrections, but not so much this time...
