Thanks for this. I was going to write a post about my experience, and still might, but will be linking to this one.
I'd previously just done 'convert to steem', and with the price points previously it had always been about what I'd expected. So when SBD picked up a little I did a larger block. BIG mistake. If I'd known about the market and that it was the way to go, I'd have come out with about 200 more Steem than I got. Live and learn though, and I've managed to convert quite a lot of SBD into Steem in the last few days through the market, thanks to @ryivhnn for the instruction on finding it
