If and when Steem is worth more than Steem Dollars (SBD), the best choice for most people would be to use the Power Up 100% option.
If the situation were the opposite and SBD was valued more than Steem, you should go with Default 50%/50%.
Gotta disagree with this. I crunched the numbers a few months ago and posted about it. The key deciding factor is not if the price of SBD’s is more than the price of Steem. It’s if the price of SBD’s is more than $1 USD. When SBD’s are more than $1, choose 50/50 and then convert them to Steem on the internal market and power up. I think @timcliff posted about it too.
Oh, you have a very good point. I remember reading about it now when you mentioned it. I'll update the article with the accurate information later today. I need to read both yours and tims articles before, so I get the details right.
Thanks for pointing this out!
Big fat caveat: in some jurisdictions, converting from SBD to Steem may be a taxable event.
I've updated the post. I used your comment as the source. I hope you don't mind. :)
