I was awake when Poloniex added Steem and SBD to their exchange. While I was transferring my SBD from Bittrex to Poloniex I watched SBD rocket up to .004 which was about $2.70 USD.
I expect a lot more users to start joining especially from the exposure we got from Poloniex. With this said, I'm going to assume that 1 SBD will get closer to the 1:1 ratio. Let people play the markets for now. I'll gladly sell my SBDs for over $1 each now and just buy them back when price comes back down.
Also there was a pretty large spread on ETH/STEEM earlier as that is one of the pairs most people overlooked. I was planning on selling most of my ETH due to the upcoming hardfork but found that trading it for STEEM worked out much better. We will start to see ETH money flowing into STEEM more and more. The real question is if we can pass ETH's market cap. :X
