That characteristic is exist as cryptocurrency born, no one can dictate or control/govern it.Like in the real stuff you want to invest there risk that you need to consider, before investing in ICO you must think about the risk of it and not only the project to be tangible. Thats one essence of ICO.
All we need for them is to find supporters for the project or the so called ICOs; all we need is investors. So how can an ICO gather such people, well there comes the advertisements, there are many ways to do that. One is to participate in this community where Bitcoin and Altcoin are the topic, so that many people would know about the project. By creating these announcements for their ICOs and granting participants to join in the campaigns that they would be having. That is a major risk right there, but by abiding their rules and advertise them it will increase the chance of finding these investors. To think that many ICOs have been forked in altcoins and not Bitcoin, therefore it is most likely that the salvation of these Altcoins are the ICOs itself, although legalizing them would be difficult.
