I don't see and big ICO in the space, and we need to understand that what people called Big ICO is based on hype, how much you spend on marketing of your project, we have seen that the hype has dried out because they are not raising ridiculous amount in the space again because how many of the so call hyped project this year has burnt their investors already
You are right. People just looking to a hype. But we must look at the team and product which they offering at first. For example some hyped ICOs raised huge money and turned to a scam. For example Gonetwork raised 47 mln usd and now seems this scammers go away with money (or even more - they didnt have nothing at the beginning - even roadmap, but stupid people invested money there anyway...). And now this cost almost nothing (in 50x below ICO price).
a large or small ico depends on its impact on the community if they bring many benefits to the community and they bring us many benefits, they are really big ico next in 2019 or 2020
