I find the longevity dynamic in bitcoin to be interesting, as well.  Even though I recognize some utility in non-bitcoin projects, frequently I am skeptical about why, frequently, they need their own tokens and cannot merely just build upon bitcoin rather than fragmenting into some separate money printing project.

There seems to be an ongoing mixed bag of outcomes regarding longevity of members, and of course, the very oldest of forum members would have only been involved in bitcoin because bitcoin was largely the ONLY game in town, yet merely being an "oldtimer" does not seem to immune folks from ending up on the scamming side of the ledger, whether there was a long con involved or if merely the short-term opportunity to scam presents itself.

Surely, longevity can allow opportunities to build credibility, yet for scammers to be shown by their behaviors in certain opportunistic situations, regarding which shit projects they end up pumping and whether or not they know those projects to be shit.
