It is very difficult to make it happen , a lot of ico's are being a total failure after their launch, and most of them are not succesfull because of their low marketing and low budget advertising.
most of them does not even reach 3/10 of the total funds that they expected to get, or what they need to make a soft cap of the total token supply.
It is risky, you need a lot of money, and a very nice idea, and of course, a good support from the community, who is hard to get at the moment,
that's true but the market will sooner or later realise that huge marketing budget often means lousy quality, as in the case of ripple because you have behind those huge marketing budget ICOs you have huge companies with huge teams behind not small efficient teams, these huge companies then have lots of expensive consultants, and in the end cannot really think for themselves. Greed contract burocracy will in the end destroy their efficiency and systematically deliver terrible investment results
there is a reason that banks have so low profit from stocks and corporations
dont spent your money for huge company ICOs they wont be efficient and bring you success!!!
they just collect a lot of capital then collapse when the funds run out distributed among those many contracted participants, and run away, with you ending up with a coin that is basically worthless after a systematic bankrupcy.
just look at ripple, after they have sold their premine ripple is will be abandoned and overshadowed by future marketing activity of competitors.
smaller teams that have long term goals are much better suited than huge company ICOs
