I've read the post and voted it from Steemfollower. Those are some nice tips. My favorite one is the one about seeing what problems the coin is supposed to solve, which also addresses the question, "Is coin X better than coin Y?" (depends on the problem the coins' are trying to solve and whether, or how well, they manage to solve it).

PS: the reference is about a game called Persona 5. Basically, it's a Japanese RPG about a group of teenagers that moonlight as vigilantes, with the power to enter corrupt people's minds and "steal" (remove) their corruption. With no more corruption in their hearts, the targeted people realize how wrong their actions were, and usually confess their crimes and turn themselves in. The group of teenagers is called The Phantom Thieves, and the leader's code name is Joker! In the game's setting, there's a forum with a poll asking questions like, "Are the Phantom Thieves just?" or, "Do you believe in the Phantom Thieves?" and shows the percentage of the general public that believes in them. If the Phantom Thieves were real, I'm sure they'd do something about those scammers! :D

This game is a field day to those who enjoy stories with involving plots and lots of character development. It's out for both PS3 and PS4. I suggest you check it out if you have the chance.
