The UK's Gambling Commission has just published a report about in-game items won by players in games like CS:GO, and the report found that 45% of 11- to 16-year-olds are aware of 'skin betting' (using items like CS:GO skins), with 11% in the same range having placed bets.
The full report goes into more detail, breaking down how many boys and girls are engaged, but the important bit is certainly about how many young people in the 11 to 16 age bracket are aware of skin betting. How can the issue be addressed?
