Thanks @barrydutton for this post. I sent my SBD to sell them on Bittrex. Then sent the resultant BTC to Poloniex to buy back SBD at lower rates (38000 vs 31186). I have earned 2 SBD just like that (because I had only 24 SBD). That's an 8 % profit.
Now, I know that my SBD are stuck on Poloniex until it enables wuthdrawals but I do have them and will get them soon. Had they been enabled, I would have kept jumping between Bittrex and Poloniex.
RE: If you have SBD / Steem Dollars to sell -- NOW is a good time to sell them on BITTREX!!
