I honestly prefer AMA's over even things like whitepapers i just find them to answer directly a lot more of the questions that actually matter while papers tend to have a lot of stuff that i could case less about, while ama's allow people to target the things that matter to the investors
I would disagree on this one; I think the whitepaper reflect much of the knowledge the team has and it also reflects their capabilities. AMA are crucial but I don't think they are as crucial as the whitepapers
i agree with you on that but i will still advise the team to organize an AMA because some people might have defficulty grasping the content of the whitepaper
