I don't see information on when sports was included in Cloudbet or it was available at the start of this platform. Do you have any information on it?
Answering this as I’m an old user of this casino. You’re right about your assumption that this casino started as bookie themselves. Their only competitors that time is very few that’s why they dominate sportsbook category in the crypto casino.
I’m actually surprised few years ago when I visited the casino since they offer already casino games which is not available even the last time I play here last 2017 IIRC.
