Bought it for 31 keys pure, sold it for 50.5 keys pure, Insanity owed me 3 keys from the previous trade with Airdog, therefore the trade was 54 keys on his side and Highway star + 0.5 keys on mine. More on his +trust I left on his profile: "Trade we made included fewer keys than agreed (52 instead of 55, my error though). Once I noticed, I messaged him to ask about those 3 additional keys and he gave me them as soon as he obtained them. Trustworthy guy!"
