I'm thinking that all ICO are suspect. Everytime they want $ before you can see your coin or a project. All ICO are scam for me, if not, the majority. Bitrad.io is one of these..
and how did you reach that conclusion ? this project was already here (the webside and wallet), when we took part in the crowdsale and all coins where sent.
Have your coins a value? I don't think. If coins will have a value of 1 satoshi at least, I will be wrong, but I'm not right now.
If you think in this way, it's best not to invest in anything at all. ISO in fact is a start-up and how successful it will be depends on many factors!
