The major draw back of initial coin offerings is scam there are lots of ico's coming up daily genuine one's and some are scam so to overcome the issue the government should either bring regulations or the community should do something to stop the scamming of ICO's. Before investing on any ico's one needs to study and understand the whole project in order to avoid scam work and disappointment as most of the ICO'S are similar or same projects been repeated it can only be avoided if there is regulation in the ICO.
