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
investors must have other plans to get profit apart from joining IEO, now most people are happier with staking and farming than joining IEO, maybe Binance is no longer doing IEOs because of the lack of investor interest in IEOs.
