Friendly matches can have betting value, but only when you follow team news, expected lineups, motivation, and how seriously each side usually treats these games. I sometimes use https://legendzbbs.com because the same account gives me pre-match and live markets for soccer, basketball, hockey, baseball, tennis, and esports while also letting me switch to slots, crash games, table games, video poker, jackpots, or live dealer tables without jumping between platforms. The odds can move fast in friendlies, so I prefer small stakes and wait for confirmed lineups before placing anything at all.
