The benefit of ICO, what i like to explain in two way as two different group meet to create one new project success. One group is ICO creator which may be a community or group another one is ICO investor.
Benefit of ICO for ICO creator:
Initial Coin Offering or ICO is a great mean to raise fund so quickly, some ICO even reached to hardcap with in one day. So it opens a huge fund towards the startup business. These fund can fulfill ones dream project and help a new innovation.
Benefit of ICO for ICO Investor:
Since ICOs are in promising state and not many people like to invest on a startup business, ICO sale going on with huge bonus offer and also price is cheap at the time of ICO (exception is also there). People are always search for new crypto currency that will give them more return than bitcoin or ethereum holding. Their hope may success or not but a successful project may give you huge profit. I like to share one experience which is with Cappasity token, the price of cappasity token from ICO(since two month) to now it is 10 times more. So who are holding Cappasity on ICO period they are getting 10 times increase of there bitcoin holdings. But not all project will be successful, many companies are creating ICO and implementing blockchain but not all are profitable, do full research before investing in any ICO.
