Leverage you SBD and Steem?

Do you ever leverage your SBD or Steem? For example, imagine that SBD was at 80c and Steem was at 40c. If you buy steem with your sbd you basically get 2 for 1. If you have 10 sbd and you buy steem you would have 20 steem. Now here is the kicker. If and when steem goes higher than sbd’s standard of $1 you can turn around and buy more sbd.

For example if steem goes to $4 (Which is not unimaginable) and sbd returns to the standard of $1 then you could turn around and buy more sbd. I have done this twice and did not notice any kind of transaction fee with blocktrades. My tactics could all be in vain if the whole systems collapses.

I was just curious if anyone else has tried this and got any good results.
