If you're asking this question, my first friendly advice for you is to not trust anything you read here on this forum, yes, including my advice

But since you're asking, I'll tell you what I feel people should do when they pick a coin:
1. Read up as much as possible about the project. Not just from the news, because those are sponsored content (paid by the devs). Look at their social media channels, get a feel about how the community works.
2. Like the whitepaper and the tech inside? Good. Do you understand it? More importantly, do you like it and think it has a chance? If not, forget it. Never support a coin you don't like or don't understand.
