People selling off because there is a big chance Bitcoin price is going to explode after the Gimini exchange and will take on a lot of mainstream investors.
Sell you Start and get Bitcoin because chances are far greater it will go up high high.
That is what I am seeing right now, most alts are going down but Start will go faster and harder because of the enormous dumping that is going to take place and PnD groups involved.
On top of that just wait until bnktothefuture projects are cashing the startcoins out for fiat/btc.
