I've noticed that it seems to be geographically based. I'm guessing there's some regulatory or law enforcement pressure on Bittrex. In particular, I've noticed complaints from Middle Easterners and particularly Iranians, as well as Russians and former CIS countries. I can only speak anecdotally, but it looks somewhat political in nature to me.
To boot, people who are fully verified are having accounts disabled too, so it's not just a matter of tightening KYC across the board. I haven't heard of anyone from the US getting accounts locked, either.
Hardly geographically alone by my experience, neither beeing middle east nor iranian myself, and how about their support department handling situation...
My account was disabled since 12/Oct to now, and i didn't receive any response from bittrex.
Unfortunately, It seems they will scam random.
Totally random and overworked. Got my account which carried zilch ballance blocked. Gone through all of their chicanery to reenable. That lasted days.
At least they are not exit scamming, since blocking zilch accounts would not enrich no one. Yes, I have peddled through all of this just to recover $0.0
I assume they are in panic mode at Bittrex, probably pressure applied by law enforcement to shut down the whole show. Now they are randomly havocing partially based upon IP location or random number generators to prevent that somehow. Revoking fully verified customers speaks volumes about their verification not beeing up to par with pressured requirements.
I can feel with them. Suggesting to move the company abroad into safer waters.
