Arthur Hayes has a big idea. He wants to build the Goldman Sachs of Bitcoin. Starting life as an equity derivatives trader, on his first day of trading, Lehman Brothers collapsed. A few years ago, he formed BitMEX, the Bitcoin Mercantile Exchange. BitMEX is trading platform that gives retail investors access to the global financial markets using Bitcoin, the Blockchain, and financial derivatives. BitMEX through the use of Bitcoin as collateral, allows anyone anywhere to trade any type of financial asset. The vision is that even the unbanked in emerging markets, with just a $1 to invest or save, might be served by this entirely new model of financial services.
