I disagree, peerplays is much better imo. They offer better returns for the investors. See: https://steemit.com/investing/@xwerk/peerplay-blockchain-primary-crowdfund-has-started-today-great-chance-for-investors-and-gamblers-alike
Edgeless keeps too much for themselfes and distributing the rest via a lottery seems very strange to me. This probably means that most of the investors will never see their investment back. If you are into gambling with the odds stacked against you, well then this may be for you. But it is a losing game.
