Recently, I saw a bunch of people chasing testnet incentives, accumulating points, and then in the group chat guessing every day whether the mainnet will issue tokens.

Basically, this is the attention economy: you think you're researching a project, but in reality, you're being led by the timeline.

My current quick fix is: don't click on hot topics immediately, wait a day before checking; if I really want to participate, I only allocate a fixed small amount as a ticket fee, never add to the position.
Because many failure cases follow the same script— the narrative gets bigger and bigger, governance becomes more chaotic, and finally liquidity disappears suddenly like a crowd dispersing.
Anyway, I’d rather miss out than pay tuition every time there's a buzz.
