I fully agree with you on the Steem Dollars, it is always best to trade them in the direction of 1 USD, because the forces will always be back to the right peg. Beside that by cashing them out now (best in Steem of course) you will help the peg to recover. I think if SD can maintain the peg and more exchanges list it it could be a very good asset to replace USDT. It is instant, so you don't have to wait long to get enough confirmations as with most other crypto's. Could be a perfect tool for arbitrage!
