I think this is temporary ban, governments always thing in a different way. When China put a suitable monitoring and taxing low, they might allow ICOs again.
yes and what i really think about this ban is that i think this is just some kind of a drama. (i hope so)
maybe they are wanting to make panic sell then buy at the bottom.
maybe they dont want people use bitcoin in their country anymore. that make people ez move their money out of china
