Let's hope for the best, I didn't know all these technical knowledge so thanks for the post... Anyway this exactly what I told my brother:
It's reversed, because instead of decreasing the value of STEEM, you increase the value of SBD. As a result, you get more STEEM tokens. Problem solved.
But I didn't say "Problem Solved at the end"... I said desperatly "It's A PROBLEM!!" because I always convert most of my SBD into STEEM already!!
