As you know IEO trend is growing but i feel IEO is profitable only for those who invested in token sale but who have purchased altcoin after launched they suffer loss majority of the investors ,as the BTT and some other altcoin examples of IEO.
No doubt about it, EIO not profitable than ICO. i have not invest in EIO yet but my friend are regret after he invested in EIO becuase he lose his funds so much. I don't know why alt of EIO can't survive in the market even tend to dropped.
I feel the same way with you that majority of investors lose after launced. maybe it makes the IEO die slowly and does not last long as a ico season
