F most investors start noticing the lapses in IEO or is the disadvantages outweigh the advantages, they might start opting out and begin to consider another model of investment or retreat back to ICO.
Until ICO projects are being regulated, I don’t think much investor will look at it again, the next direction that they might be looking at is that of STO if IEO fails, but I think the exchanges are strong enough to keep IEO active for a very long time, especially the ones being handled by reputable exchanges. If we still then fall victim of scammers by not following the rules, then we should be held accountable and not IEO.
