I have registered on Uquid and made a deposit of 0.09ETH on 30/12/2017. ETH price between 30/12/2017 and 2/01/2018 has never dipped below 670USD between those 2 dates. It actually varied between 700USD and 797USD according to coindesk.
Check this out. The deposit estimate on their OWN website said that 0.09ETH should be around 66USD, which was fine and according to the price ETH was hovering around at that time.
Deposit via crypto, which was supposed to be "realtime", finally got "completed" on January 2nd 2018. Ok fine ,it was New Year, maybe their personnel had a day off or they were short-staffed. But when it finally got completed I was credited with an amazing 43USD... LOL. SO the ETH price they used for my deposit was a magnificent 477USD, a jaw dropping 36% lower price than what the actual price was on Dec 30 and a whopping 40% lower price than ETH was on January 2nd when the "realtime" deposit was completed.
So if I had opted to deposit 1000USD in ETH I would have actually gotten an amazing 600USD for my ETH deposit.
Of course ,support has no answer on my ticket after 5 days since I have opened it. Below are screenshots from my "deposit" transaction and my (oneway) conversation with their "support". Support "should be contacting users 24hours at the latest after the incident has been opened", in case anyone wonders LMAO.
