There is no side of ICOs that is logical to me, but I've also invested in ICOs in the past because I wanted to make profit, while most are scam, only 1% of the rest is logical in such senses.
So to make it 1% logical , do ICOs have to spent millions to create a false hype to grab investors' attention... how successful it would be if same effort goes to the actual product or service ...rather entertaining such entities.
