Circle is a company that raised $140 million form the likes of Goldman Sachs, IDG Capital Partners, Breyer Capital, Accel Partners, General Catalyst Partners, Baidu, CICC Alpha, EverBright, WangXiang and CreditEase. Their slogan is send money in a text. Will this put poloniex on a different playing field. Will they have mobile apps that will make trading crypto more like wall street and bring this main stream? If you go take a look at their homepage https://www.circle.com it looks like an interesting concept. They might integrate a payment option inside an exchange. I don't know how much of this company Goldman ownes, but I would think they have a vested interest more and more in crypto. I feel they see this space lasting a fairly long time or they would not bother!
