Going by my experience, 100% of the people saying "do your own research" are either shills or they are getting into a project without having no idea of how things work. If people can explain easily and if it is a legit opportunity, they wouldn't be saying "do your research", this will just be accumulating as much as they could without making too much of a fuss about it.

Corollary: any coin that is on the up-and-up and you can not easily explain the tokenomics is worthless.
