the only thing that holding many back from investing in arbitrum for long term holding is that I guess is the fact that even right now there are many L2 waiting to make some release about their token and I think
that in the future will overshadow greatly ARB and many of similar tokens, its fine if you got an airdrop and holding it for future investment purpose but I guess its somewhat lacking when it comes to holding it by investing it right now.
it has been going downhill ever since and I think it will hardly rise again like in the early days when it just recently got listed.
i would assume that until something like zksync and the other already released, it will just keeps going down hill.
