Is the Operation Breakout Weapon Case worth opening?
Opening one Operation Breakout Weapon Case costs about $13.26: $10.76 for the case plus $2.50 for the key. Weighting every item by its real drop chance, wear and the 10% StatTrak chance, the expected value of one open is about $5.84, or roughly 44% of what you spend. Over 100 opens that is an expected loss of around $741.51. Almost all of the value sits in the Covert and knife slots, which together land on just 0.90% of opens, so most real openings return far less than the average. That is why trying it in the simulator first is the smart move.
