There is almost always a pump and dump. The benefit is that more people will be comfortable with using the various STEEM platforms when they can sell their SBD even if they didn't speak English or Korean. It would give incentive for the rest of the world to create an account. They will no longer be left out.

The other thing it does is provide an avenue for investors to buy and trade SBD. Despite all the efforts from the witnesses, they can't keep the price of SBD down. This is a good thing. It goes to show how much investors believe in this system. The reality is the investors are paying for our work here and they are happy in doing so. SBD trading on exchanges is a major influence in Steemit growth.

More exchanges listing SBD = more Steemit accounts.
More Steemit accounts = higher STEEM price.
