I want to believe most exchanges are really coming out to delist shit coins from their market; probably they are beginning to understand it would not help the growth of their exchange in anyway. I wonder what they were thinking in the first place anyway. They thought a shit or scam coin will just grow all of a sudden to become something substantial in the long run.
With the way the space is maturing, the possibilities of regulation, I have always known that sanity at some point will possibly roll back in action into this space eventually and there won't be room at all for any shit coins.
