Better to do extensive research first before making an investment in ICO's. Some of the ICO's right now are just scams, better to look into their white paper if they have a concrete plan for their project.

To be honest most of the choices are all important and i don't see any significant difference that one is better than the other to get focused on, but as for the discussion i will go with the whitepaper including its roadmap because you can analyze there the progress they want to take in and you can guess if the team behind is very strict and serious with the project.

A lawyer with a boring perspective here ), take the time to look at the terms and conditions. At least check what the rights are and the issuer plans to do with the proceeds.

Searching may be a good way to learn some informations about the ICOs and that can help to choose the right ICO. But we can not underestimate the affect of the luck.

Several important components come into play when selecting a successful ico to invest in.  Obviously the project itself should fill a gap, an area that has either not been explored or has deficiencies still.  The whitepaper and roadmap are also important along with a team that is knowledgeable in the industry that the coin promotes.  Finally all of these ingredients need to be backed by successful marketing to ensure that the coin becomes well known to potential investors.

Of course, the developer of the coins must be active and follows by their team also. If this happen in every ico project, surely there is a big chances that ico will in the near future will become successful in the end

Nobody knows for sure which ico will be successful. They are just doing research and predict it. Maybe success maybe not.
But, it is better we do research rather than just blind prediction.
One thing normally i know very important, that is if the project has real working product or not. If they have mostly ( not always ) they be successful.

ICO is very risky because so many scammers and everyone want to run its own ICO, but you can learn a project carefuly, know what the team do, who are its memebers, read whitepapers, website and so on and after that make a right choice. Good luck!

If u don't wanna find yourself without pants, u should know few things to make a good investment:
- at first, look at founder's biography and previous business experience
- read white paper carefully, to find real methods, that ICO team suggests
- check, if market is ready for product of ICO
- check activity on social media, and cryptoforums
If after all, u still trust in project - invest.

in fact it is very difficult to study the information and make sure that it is true, therefore the importance of choosing ico companies is a top priority in investments or even participation in the generosity of the program. First of all, I draw attention to the country in which the project was born and to the main developers of the project.
