I've got two things to tell you:
1. an altcoin with an ICO will never even be able to come close to bitcoin, let alone exceed it. you forgot that the ICO is there for the developer to make a quick amount of free money.
2. have you even checked the numerous issues that altcoins have with scaling? I really doubt it. I suggest doing some research in this matter and see that they have even more problems that will make you beg for the problems of bitcoin
but people usually compare bitcoin, a massively used cryptocurrency with about 350,000 transactions each day with an altcoin with barely 1,000 transaction per day and think that altcoin doesn't have bitcoin's scaling issues.
