I still don't have any info on Bitebtc for you. All I know is I've been waiting forever to get verified so I don't really think even if I was accepted that I would use it at all. Stay safe out there folks
Unfortunately it looks like Bitebtc has quite a few unhappy customers : https://bitcointalksearch.org/topic/bitebtc-is-a-scam-exchange-4612714
Personally I'd avoid using them until the various issues including verification wait times, stuck deposits etc get resolved, I'm more than happy to wait until PRiV gets lasted on other exchanges which I'm very confident it will
It's what everybody was saying, but until raske passed the KYC and had the opportunity to try how it worked, it wasn't obvious that it was plagued with bots... Nice that our community members always keep us informed
