The only thing that i can advise to the newbies out there, maybe including me of course, is to do a personal study on their website. read the whitepaper, review the team members, and understanding what they could offer offer to the community. Their main project or focus or a product is the most important if this could be helpful to the community or to the business., those projects that are related to bitcoin trading or etc are not that really impressive based on my opinion.

Do some DYOR before you promote anything. Of course, check their media channels if it could have lots of supporters
