Help!!! How to convert STEEM POWER to SBD without losing my shirt?!?

Newbie Question - how to convert STEEM POWER to SBD without losing my shirt?

I want to convert STEEM POWER to SBD around around equal values, but have not figured out how yet.

the only way that I can figure out is to Power Down the Steem Power to STEEM. This takes 13 weeks?!?

Then go out to the Market and sell the STEEM and buy SBD - but -

if I am looking at this right there is a HUGE penalty for doing this. For example,

I just "Paid 4.914 STEEM for 4.550 SBD"

close to a "1 to 1" trade, yes? That would be okay, except

as I understand it the 4.914 STEEM is worth about 5x$4 = $20 and the

SBD is worth 4.55 x $1 = $4.55 - so -

it costs me $20 usd to get $4.55 usd ???

am I reading this right?

is there a better way to get from Steem Power to SBD's???
