Most probably, this will be the immediate effect of this report coming from no less than SEC of USA. Now, I think, many of the ICOs of recent weeks have already closed their door of participation from those living in USA and USA citizens wherever they might be based on. This stand from SEC is already anticipated months ago and this is not quite surprising. In fact, what is surprising is that it took SEC some time to release its official stand on ICO.
There are good ICOs and there can be bad ICOs and since many of the potential investors are not equip and even not qualified to do their own due diligence, it is now going to be regulated by the government before any organization or project can open its ICO to the public.
But this is going to be effective only in the land of USA and will not cover those based in other countries. So the best way to avoid SEC is of course to never let any American get in his way to your ICO.
