Major Financial Players Launch Crypto Exchange, Threatening Coinbase.

EDX Markets, a new crypto exchange backed by Fidelity Digital Assets, Charles Schwab and Citadel Securities, has launched in the US after building out its technology for the past nine months. The exchange only offers four tokens – bitcoin, ethereum, litecoin and Bitcoin Cash – partly because of the unclear regulatory landscape in the US. EDX Markets doesn't custody customers' digital assets, instead, users will have to go through financial intermediaries to buy and sell crypto assets, similar to how trades are executed on the New York Stock Exchange or the Nasdaq.
