As long as you can trade the SBD for more steem than you make at 100% power up take the SBD. The broken peg creates the power of those who wish to power up to get higher SP by trading them in for steem. Don't sell yourself short thinking everyone will try to help the peg, right now the majority of the SBD's are going to the Bid Bots and to @freedom. He has stacked a quarter million of them so far in his account and he funds most of the vote sellers with delegation.
