Well investors are now wise and one thing that makes Binance IEO Dumping is the difficulty attached to participating in the IEO. The modus operandi of the IEO activities are just too cumbersome hence the reason for the massive dumping. Its just asif the IEO are only mearnt for whale and there are no locked period attached to most of the IEO
I do not really think that there is any whale participating in ieos, first of all because if they wanted they could buy the entire supply of an ieo and second because even if they invested in an ieo and they were successful in their investment the money they are going to get is not going to be worth the effort for them, make no mistake the market of ieos is for small investors that do not really know how to profit from good coins like bitcoin, because if you knew how to do that you will never give any attention to ieos.
