IEOs have eliminated many of the problems of ICOs. In the past, there were many scams through ICOs. IEOs created a safer opportunity for investors under the supervision of exchanges.
Launchpool and launchpad has gradually gained popularity than ICOs due safety but I still feel the reward rate should be a bit increased. Something that should commensurate with assets commitment. No doubt Binance has been doing well but I still feel Bitget should be second on the chart cos their launchpool and launchpad have produced a decent ROI since inception.
