You are correct because I have experience this kind of scenario where I was left behind on the update and I lose the value of my token as there was a deadline, so I learn a lesson from that on not holding a lot of coins/tokens.
If you want a long term hodl, hold few tokens you can always monitor their development progress.
I do hold major coins like Bitcoin, ETH, and BNB because these are the coins I believe will dominate in the future.
And it's easy to update on these three as they are popular, lots of article will show when there is a changes or an update.
