in my opinion it's not weak but IEO is no longer hype so the price increase in Binance is not too big but in my opinion it's not a problem because at least investors still get a profit
People were also buying IEO coin based on the hype. You're correct if the hype was playing the main role but it looks like those projects were not getting hyped when the IEO was happening. As far as i know a project that was getting hyped will be getting so many talk in various tele group. I rarely seen people who have been discussing about injective or even exie gaming.
Those project were getting small hype only at least 1x ROI is better rather than nothing.
