opened a 3 year old wallet expecting a graveyard and found something that's still printing. is this a buy or a trap?

A user discovered a SUSHI token wallet from 2022, expecting it to be defunct, but found the protocol is still active with a new perps product and significant volume. However, the token's price has dropped 99% from its 2021 peak, and total value locked (TVL) has plummeted from $8 billion to near zero.
