When I'm trenching/ sizing in, I like to sort coins into one of two buckets: narrative coins and dev coins

Narrative coins are coins that rely on news/ belief alone and don't require a dev to run, they can always be revived if the narrative aligns and interest is there. These coins are more in line with a movement
Examples: $FART (funny and TT idea), $GOAT (TT made coin), $PEPE (most popular meme)

Dev coins are coins that need a dev/ core team to run it and maintain it. These coins can never come back after being rugged and rely entirely on the work the dev has already done/ will do.
Examples: $AIXBT, Zerebro and manufactured character coins like $MUMU

Of course, this is very rough and these things can vary (always exceptions etc)  but imo it's important to understand both and to know what factors affect your bag's ability to pump and make you rich (or homeless).

I think you should leave dust in coins with any ounce of narrative where possible even after it "rugs" as their price is solely dependent on how much the market likes the idea of it in the current meta. Team coins are also dependent on the dev so it can be harder to judge potential with an extra moving cog.

Pros and cons to both. While "narrative" coins are solely limited by an idea, my biggest wins personally have been on these coins as your judgement is not restricted by the actions of a dev or how good a product is so it's easier to tell when you have a winner and determine a "ceiling" price (not to mention it's easier to get entries without dev bundling).

Just some thoughts 😃
