I wonder if anyone has chosen a bookmaker specifically because of stability, and not because of bonuses and advertising, and hasn’t regretted it later?

I stopped chasing promotions a long time ago and choose a bookmaker based on how they operate over the course of months, not just the first few days. Stability is evident in the little things: the site never crashes, the lineup is updated without surprises, and settlements are on time. That's why I stuck with https://1xbet.lk/en , even though I didn't seriously consider it at first. I haven't had a single strange bet settlement issue in a year. They offer bonuses, but they're not pushy, and that's a plus for me personally.
