Blockchain Summit Hong Kong is part of the largest dedicated Blockchain event series in the World and it's a good option for new ICOs. Anyway, 3 months remain before the event takes place, I think by that time, Icechain will have already listed on exchange and some progress to share there.
Seems that the IceChain team already got a handful of funds from their private investors. Is this the reason why the ICO will take only 5 days based from your website? That's relatively short as compared to others who are running their ICO for months and months. And I like this project because they are not focused in listing their coins in exchanges but rather their actual development. It's easier to list your coin but the stability of price would be too difficult if your platform is empty.
They said that they have big investors backing this project and ready to buy all tokens and that's why there is only 20% of total supply for public sale. So I think there are a big investors behind the sense who brought a big percentage for some privileges and good discount.
