That's a good question! In the video, I outline that the coin, or token, should have a unique product, serve a purpose, have an experienced team, community support and easily be able to get information on the project. Using this simple framework, you'll be able to weed out some of the coins.
Majority of the coins that you mentioned fit the bill, but you can dig deeper to find out if its a good fit for your portfolio.
What interested you in Steller?
Too be very frank, I just heard about it and watched some youtube videos and bought like penny stock. Someday it will give appreciation.
