just wanted to post an update on poloniex from @yacov. Sadly, although poloniex does seem to be trading STEEM/SBD, his funds (and I believe those funds of many others), still appear to be locked up in limbo...
For some reason steem is Temporarily Disabled in Poloniex and I cannot move my steem to my Steemit account. This is going on since about a week.
