If it has a good ICO and a good price already raised so that means it can hit it's max cap easily if they are already in a big amount just in the Pre-ICO. and if there are many people joining campaigns. especially when legendary joins.
here every ICO have implementation plan for run project you follow to get indicator success
What project do you mean ? Is it Bounty ? Is it Campaign ? Is it Signature Campaign or Social Media Campaign ?
There are so many project in this forum. If you want to join Signature Campaign, you must see the guides and you will know which one is active and paying. But, not all campaign is written there.. sometimes you can see people with the signature but you never see thread.
Not all ICO or project that promoted by campaign is legit and trusted. Some may be scam one day.
