Frankly, I also surprised to see SBD is pumping while other altcoins are decreasing following Bitcoin.

After that, I did some studies on the SBD concept.

Actually, SBD is one of a cryptocurrency of the Steem blockchain, is considered to be more stable. It is intended to be valued 1:1 with the US dollar, which means that 1 SBD should be equal to the amount of Steem that can be bought with 1 USD.

Due to this concept, lots of cryptocurrency investors were invested in this stable currency. That is why SBD was pumped during this crypto DIP.
