> If you mean held as in self-custody then I agree.

Yes, this is what I mean. Whenever you self-custodied BTC, and have since, that’s your class year, IMO. I believe this is roughly the “class” definition as it’s used in the vernacular.

If we wanted to roll shitcoins into the definition, I’d say one’s class is the last year they held zero BTC, OR bought a shitcoin, whichever is more recent. But here we’re moving from descriptive lexicography to prescriptive.
