Thanks for the good insight. I was thinking to try some of the major exchanges. Now i have got reason not engage with bitrex. Is it always that you have either a good volume or 1 btc plus withdrawal without great verification burden?
I think poloniex is legit now. They were acquired by circle you know. Haven't heard anyone complaining so far.
for the record, they finally accepted my verification documents, had to send one photo over e-mail which is a sign that they handled my case manually at last.
