According to Flash, his Golden Mouse is currently locked in the bank's safe-deposit box.
Golden Mouse is the highest honor in Starcraft, namely, three-time OSL champions. It's composed of 275 grams of gold. By the current value, it's more than 12 million Korean won. Most Golden Mouse owners keep it at home, but Flash puts it in the bank's safe-deposit box.
This is because Flash's home was almost burgled a few years ago. One day after midnight, Flash's mother heard some noises outside their door. She got up and saw 6 people were trying to lever the door. She called the police in time and the burglars were not able to lever the door, so nothing was stolen. After this, Flash thought keeping valuable things at home is not safe anymore, so he decided to put it in the bank's safe-deposit box instead.
Flash said: "Although no one was hurt and nothing was stolen, after that day, I discussed with my parents and we thought it's better to put it [the Golden Mouse] in a safer place. Now the Golden Mouse is in the bank's safe-deposit box, and only I know where it is. There is definitely some costs [of keeping it in the bank], but this thing is the testimony of three OSL champions. I absolutely can't lose it before I show it to my children."
Saw speculation on reddit that flash might be going on live on three next week to announce he's joining EG. Now that's pretty far fetched speculation, but it honestly wouldn't surprise me if flash did join eg, with money freed up by idra/stephano retiring and getting more new sponsors recently.
