Reaching the hardcap quickly is by no means the only sign of a succesful ICO, and a succesful ICO is by no means the guarantee of a succesul coin. I spoke with some of the Change devs and their plans will just continue as planned, only a little bit slower. I believe they'll raise 50.000ETH by the end, which is about 15 million dollars. That's a great accomplishment. Sure, Centra got a lot more, but mostly because they paid Floyd to endorse the product. Sooner or later the investors will realise celebs don't know what they're talking about and they'll sell their coins, just like they did with Stox, and just like every single celebrity endorsed coin. Change is backed by real investors, people who know the market, people who helped build the market, not just people who got paid a ton of money to post an instagram picture (not saying Centra is necessarily a bad investment, but a lot of smart people see celebrity endorsements as a last resort to boost popularity)
