More skins on the website will make the coin a more viable currency. Hopefully they are buying lots of bargain skins elsewhere and reselling them on their site to buy with skincoin
Skincoin is becoming popular in CIS/europe and maybe after it will be properly introduced to other regions, price can go up. IMO, It's also better for a coin to be used primarily in its main purpose (which in skincoin's case is for betting)
