The addition of 3 new assets on Gemini and being licensed by the New York Department of Financial Services (NYDFS) shows Gemini is making a wider spectrum of crypto available to institutional investors
Why would they add beecash? wtf?
Maybe because they expect that Bitcoin Cash's greater utility -- as compared to Bitcoin Segwit -- will result in continued increase in market share for BCH.
Or maybe just because it is market cap #4. Or market cap #2 as defined by free of problematic Securities issues - which excludes Ethereum and Ripple due to their initial distributions.
Either way, they expect to make money by offering it.
