I want to know that is this going to help the upcoming coins or not?
In raising funds, probably yes. Exchanges where token sales where held would make sure that the soft cap is met because they can also be affected. Just be aware that there was an exchange exposed for faking the volume to make it look like the token sale was a success.
That is why we should only trust reputable exchanges like Binance, Coinbase, etc. I envy and admire Binance exchange who are strict in accepting the requirements of incoming tokens. Hence ,IEO is much better project than ICO when it comes to security and will prevent scams from faking the project itself.
