CME has a big influence in the eyes of investors (especially stocks and forex). CME also known as main trading center gate before entering US and European markets. An entity cannot easily be listed in CME market. In order to be listed on CME, CME team will do their own due diligence.

On this basis, indirectly when btc is listed on CME, investors psychologically think that btc has its own distinctive features so that CME wants to list btc into their platform. And directly, btc trading activities in CME will affect btc movements. Even though exchanges like binance, bitmax, coinbase have a large trading volume, they are still inferior to CME's influence and reputation.

Key : influence and reputation.
