whatever be the killer of btc, if there is one, it won't reveal itself with an ico first of all.  second point, it won't have dutch auction to prove itself lol. the advisory team shall not consist of people who predict demise of btc just to pump there own shitty ico. also btc killer has to sound simple, the developers won't be hired, they will start the working engine by themselves also if someone has to be btc killer they won't appoint a CEO to make it more complicated. all in all metronome is very away from being a bitcoin killer. anti-fragility is hard to achieve (which bitcoin has) but once it gets achieved it makes the system very robust.
