IPOs are all scams because as I've said a billion times before, the IPO creator can make thousands of mule accounts with 1 BTC in them each, send them all to the IPO addresses, get infinite premine/equity, then all the BTC comes back to him anyway.  If you believed you could actually pull this project off, you would just give yourself some kind of equity (premine in other words) for it and not ask for BTC.
