Let's talk about the two types of proofs used by Rollups.
L2BEAT classifies Rollups into three stages—Stage 0, 1, and 2—based on criteria such as the proof system and whether users can exit on their own.
Honestly, I only learned this later: when withdrawing from an Optimistic Rollup, allow for a challenge period of about a week. If you need the money urgently, don't wait until the last minute to withdraw.
The networks for $ARB and $OP use Optimistic Rollups, while $STRK uses the ZK approach. Currently 0.1547.
There's nothing wrong with playing it safe. Staying in the game matters much more than how much you make in a single round.
