..Optimism token that looks like a good one to hold for long term ..
It is only a
look-like, doesn't mean it is
good enough.
Sometimes, hacks in the crypto world can make a certain project dead, moreover if the developer team cannot overcome the problem and make any progress and development. It seems to be a dead-soon project. Like BP also had similar cases, having very dropped and crashed price because of hack problems. In this case, the team cannot solve the problems and the price keep crashing, maybe this can be a dead soon project. Sadly, I have the token and I have no hope again for this. This may be the same as your point, of that token. Just let it be and make a lesson from this experience. It is better to invest in top coins only, moreover only on Bitcoin as the main choice.
