if still can participate in register in market cobinhood to get token Miles
I am trying to register but can not or may have closed not receive new registrants?
The registration you need will be available after open beta (est timeframe is dec 18th, so register then and have cob in your account by jan 5th to get the free CMT)
If you run a zero trading fee cryptocurrency exchange how are you going to fund further development, security measures and generally operational costs?
They will eventually sell the ico underwriting tokens they receive at a discount to cob holders, they will also earn money from the margin trading.
will the COB token be listed on cobinhood exchange itself in order to trade it?
Yes, it's currently listed on the beta and presumably will be passed on to the live exchange.
