first of all : i hope that there will be alot exchange possibilitys in the future the more the better !
i am not sure who is behind this web, but this is not negative i am trying to be positive but
this is real bullshit :
from tweet :
Upcoming opt-in security feature: authorization of IP addresses via e-mail.
source :
https://www.coinmarket.io/ twitter account : @CoinMarketio
this authorization is making no sense at all !!! [ becouse ip adresses change and then ? how do you make your authorization ?]
[2] for authorization i propose to use a extra pin option like crypto-trade , email and pincode like many pools,
