oh yeah bittrex is really making things harder and harder
I started using them like less than a month ago after poloniex stopped dealing with my country , used them just to buy clams since it's the only exchange left with good volume to buy and sell clams
before the fork I was able to withdraw more than 0.2 worth of btc a day , don't know how much excatly cause I was newbie in the site and didn't know where to check their limits
after the fork I was trying to withdraw 40 clams and then kept getting the message that I reached the limits and I need to wait 24 hours or verify
asked one of my friends if this is an error and he told me where to check the limits and found that my new limits is 0.025 btc a day

so I tried to verify my account , their verification system based on info and mobile number failed so I tried to go for enhanced verification
but everytime I submit my passport and my photo their system refuse it and says that there are missing info in my documents which is not true at all all photos are complete and clear
tried to reach their support many times , I told them that I'm ok with verifying my account but I'm not able to so asked them if it's ok if they can verify it manually like I send them my photos through the ticket and they check it manually
I kept getting the same message over and over again , that they can't verify manually and that I need to verify through the system in their site
but all my trys were failures , so I gave up after they kept sending me the same message over and over again
they need to be more helpful for sure
Likely if Polo wont take you as a customer Bittrex cannot either. Their system is nicely telling you to move on. Both are US based exchanges and have the same regulations.
