KYC process review

Every time I go through the KYC stuff on a new casino, it feels like a mix of needing patience and trying to finish a puzzle with missing pieces. Some sites only want basic docs and I’m back spinning roulette within an hour, but others drag it out for days and suddenly I need proof of where my electricity comes from. The crypto ones seem smoother but there’s still always that last hurdle where I have to dig through old emails or find a decent scan of a bill.

I'm all for safe gambling and keeping things clean but sometimes it almost feels like they’re trying to see if I'll give up before I get my bonus. Has anyone found any patterns on which docs they ask for or how to make sure it actually gets sorted the first time?
