I have been converting a small amount for several weeks now. My first conversion was for 50 SBD (75 Steem at the time) and I am now up to 136 Steem (58 SBD). I only had one conversion not going in my favor. This will be my 15th conversion and hopefully we don't see a big drop in the price of Steem in the next few days. For the operation I have been using Steemconnect (which is another option).
