Update, and it is a bad one.
On 20 August their support told me the case was escalated. On 24 August they closed it in writing: "direct withdrawals, deposits, and USDT conversions for ZARO are completely unavailable. The only option is to use the active trading pair to swap for USDT based on current market prices."
No ticket reference, no name, no date, and they misspelled the ticker. So this is now official from their side: no manual withdrawal, ever, and the only exit is selling into their own book, whose depth has dropped roughly 60 percent since withdrawals were disabled. That is not an exit, that is a haircut.
@barryson thanks, and I agree with your conclusion. Deposit only, at best.
Two questions for the team: does anyone have a working contact at DigiFinex, and should ZANO/USDT there still be presented as an active market on zano.org/exchanges when the asset cannot leave the exchange? Happy to share the full email thread privately.
