Since I also own Arbitrum tokens, my ideal buy zone also if we will fall below $1. For long term, Arbitrum is my player also.
Yes you have a good eye 
In my opinion the best price range is between ~0.95-1$ for now and if the price go down we can continue to Average down using Dollar Cost averaging and the good thing this is a layer 2 coin meaning if we dont have money to buy more we can stake it and watch it grow
