In my opinion
SBD is pegged but Steem is not pegged and steem price drop from 4$ to 1$
But that is a good opportunity to power up our steem power because we can buy steem on cheaper price.

Indirectly pegged. But I started to think that right word to use is "correlation" even if little and "pegged" might not be the right word in steem case. I will study this case and in my next analysis, I'll explain this part. Anyways, thanks guys.
