Looks like, at the moment, they don't support deposits or withdrawals of the cryptocurrency you're trading, so if anything, they seem more like ETNs of the cryptos than the actual cryptos themselves? I imagine it's for the reason you stated until they get the security protocols in order. Not sure how they're getting around SEC approval, unless it's something sort of like an IOU loophole where you can only sell the IOU, but not redeem it for the coins yet per their terms of service? I have no clue.
