they seem to be re-establishing fiat tunnels now. I assume they "somehow" own/run advcash. But now they have tether too and a handful of other options I don't know.
What a world we are living in.
Yes, my suspicion from the day of launch was that Advcash is operated by them. Perhaps others, too. It would be impossible to establish that from online sleuthing, but it's conceivable that they would buy a payment processor and operate as they always have. Why not?
They accepted Tether for deposits earlier this year; it's possible they held some in reserve. I imagine they may have acquired a good deal from Bitfinex, given the apparent demand for fiat output. Hopefully the exodus blows over and the exchange is viable for the longer term.
