How did you claim the ARB token? Unfortunately I couldn't claim earlier because the website was down and at the time of listing the price was above $10 then it became a dump because of the disposal of tokens resulting from the airdrop that they claimed and then sold it.
I claimed it manually through arbscan. It was working when the main site down due to the so many traffics that came at the same time. I have sold mine @$7. People who didn't know how to claim by interacted with contract unable to sell their token as high price.
I saw few comments on Twitter to claim it manually but didn't out of fear. $7 was a good price, it will take a while for arb to stabilize in that prize point again. If I was you, I would buy back and at least get the airdrop portion back.
