ICO/IPO coin only benefits Developers by providing instant BTC to them not miners or investors.A few features for one or two weeks and then either dev disappears or coin loose interest.
Considering that these so called devs are not coming up with anything new (most doesn't even have anon feature) pretty much makes ICO/IPO nothing more but a tool for scammers to play with. I think if devs are confident in their coins they should invest in them.
