I do think this is completely a good thing as it can affect the success of some small ICOs.Imagine giving out 1 million $ of the total sums realized during an ICO.This will only enrich the owners of such exchanges.I think it was caused by the proliferation of ICOs.Maybe decentralized exchanges will be better in this regard.
I think the ICO should be regulated so that ordinary people will not be scamed like they are at the moment.
