Unfortunately the issue with poloniex is over 2-3 weeks now. I remember 3 weeks ago i had a withdraw error, chat was overloaded with trolls or people with similar issues.
It took over a week to have the error corrected, after opening a tick with them (as it was requested by chat moderator). I recently tested when they reopened steem, to transfer from bittrex to poloniex by sending one SBD, i think i never saw it reaching poloniex , maybe lost it.
I am really discouraged by this, i don't really care if it has a larger 'variety' of coins or not, quality of service and speed of transactions are the most important features that i value. Having their chat closed to re-arrange their resources was the last nail on the coffin.
What scares me if that could create domino effect on other sites as well, if multiple owners move their funds from one exchange to another, could this eventually impact bittrex and others the same way? Is there any danger of permanent crash?
Many thanks for your research by the way, spending your energy and time for these trivial information is could example of a cooperating community!
