I see the activity in exchange is there already buy and sell, is this open to the public or just a trial phase? in the settings I check there is no security like Google Authenticattor, why to register only through Facebook? how about people don't have Facebook but have gmail ?
It's open to the public. We've given up on Google Authenticator, it'll be replaced with a proprietary 2FA solution. Facebook registration is just a bonus feature, you can still create an account the regular way (email verification).
Which criteria do you select token to be listed on your stock market?
