If I were you, I will take whitepaper as nothing these days. If you are on the lookout for whitepaper, you will get some smart scammers that would design one for you, write it pretty well and then you will then start wondering where you missed it eventually when you get scammed. Some have made scamming their office now and they will do all it takes to deceive people. For me, the team and the product is all I need, and every other thing is secondary.

In my list of criteria the first one that I do not ever miss is the team. If the team cannot do it for me based on their past achievements and based on digging them to be real, then there is really no reason for me to go further reading anything about the project, even though I always try to get a quick glimpse of the project first with the website. After that, I can then access the project and find if there is a product and the possibility of being a useful one.
