These days ICO is less popular. The most significant emerging trend in the crypto markets at the moment is IEO (Initial Exchange Offering). It's almost the same as ICO but IEO token sales are executed by crypto exchanges rather than the companies that seek to raise capital themselves.
That trend seems to be getting more popular, we can say that investors are now choosing IEO or ICO, for the reason that the risk is reduce.
All we want is just investors to feel safe in investing so the flow of money in crypto would increase, and that increase the demand of the coins in the market, which is good for the overall standing. ICO would survive, but how long? if there is no improvement in the current set-up, they will be gone in no time.
