Just thinking back to what went down with those VINE and AI perpetual futures contracts last year. A major exchange pulled the plug on both around April 2025, and honestly it was a pretty rough situation for people holding positions. They gave traders a few days notice before closing everything out automatically.

The whole thing happened because these pairs weren't moving enough volume - classic delisting scenario. When perpetual futures contracts don't attract liquidity, exchanges usually cut them loose. Can't blame them really, but it definitely caught some traders off guard. If you had open positions and didn't close them manually, the system just settled everything at whatever the last price was. Some people ate losses they weren't expecting.

What struck me most was how it highlighted the importance of monitoring your perpetual futures positions closely. These delistings happen more often than people think, especially with smaller cap tokens. You could still trade the spot tokens after, but the leverage plays were gone. A lot of traders migrated to other AI-focused tokens or just moved to different exchanges.

The whole experience was a good reminder that perpetual futures markets can shift pretty quickly. If you're holding contracts on smaller tokens, you really need to stay on top of exchange announcements. Not trying to be preachy, but it's one of those things that seems obvious until it actually happens to your portfolio. Did anyone else get caught in something like this?
