Richfund is the biggest bitcoin hedge fund company in China. The CEO is well-respected among Chinese bitcoin community. They have arbitrage services with the biggest exchanges such as Bifinex, Kraken, Huobi and others. The website is richfund.pe. They are trying to expand their otc trading and has done many successful trading. They are willing to do trade over localbitcoin for their escrow service and are willing to cover the 1% localbitcoin trading fee. Their mission, to the best of my understanding, is to help other professional and large bitcoin traders profit. Of course they will make profit too but it is lower than the traders they work with (because they will pay the 1% localbitcoin fee). Ultimately, they want to set up a network of professional traders.
