Hi guys, Im relatively new to this ICO thing. I still need to study the whitepaper of this project. But what payments methods can I use?

You can buy ID tokens with ETH,BTC and USD.

Is it too late to join now, what's the bonus available at the moment?

30% discount available

Is this bonus locked for the some period of time or not, and when is distribution of the tokens if I join now?

I think that only team and advisor tokens are locked,and maybe seed.No need to lock those tokens,since 30% is not too big to cause dumping.

Yes, maybe there is no need to lock bonus tokens if team and advisor tokens are locked.
