The funny thing about it is that you rarely see any one sell any coins to the exchange and if they do they are in small quantities. So my question is where do they get there stock from they must have sold > 500,00 in the last week?
A lot of it may be from the coins on the debit cards. There where 150 backers, and each card got 25000 start. That's 3,75 million coins. If somebody refills their card with startcoin I guess it will also be sold the same way. They obviously don't want to depress the startcoin price, so it's always higher than the Bittrex price. It's for those who want to buy a lot of start without affecting the price much.
I was one of those 150, and no-one received 25000 START. We all received a debit card topped up with 250 USD.
EDIT. I did buy 10500 START with the 250 USD, not sure what the others did with their money
