- whitepaper: very important, where the core of the project is explaned. This is where I can see if a project is only a copy of a copy of others or it's original
- checking team: I check team in linkeding, if I don't find them, I would pass.
- telegram channel: I take a look at questions and answers in telegram chat.
Is it usual to see the devs themselves answering questions on these telegram chats?
Usually it's the community managers that answer first, but if you ask a more technical question they'll ping DEV's to have better answers.
(At least thet's my experience)
