it depends on the ICO that you're going to invest because this season, not all ICOs are legitimate, probably half of them are scams and bogus.
But if you really know that ICO and the dev teams behind that project then it's a good start to hit that invest button.
it's good to invest ICO while they're on their kickstart but it's better to invest on new altcoins when they bumped on coin exchanges because we can sure that they're not scam and bogus especially when the trade volume is at least $50,000 daily.
