Graviex is a total scam and stealing peoples coins. Stop using this exchange. They are not registered anywhere. No license to track nor office location. They can do an exit scam anytime. Stay away from this exchange as they are unlicensed.
I've been using Graviex like 5 years and never lost a withdrawal... Had some missing deposits through the years but they have all been resolved through support.
License don't matter to me, I'd rather see regulators out the door myself.
1st rule of crypto still applies,
not your keys - not your coins. Don't keep funds dormant on exchanges.
