Finally figured out why I've never won a slot game during DEFCON..

Just completed my 10th audit as a contractor Zellic and these are my top favourite things about this place: 1. They have a diverse and deep talent pool. World top Web security, Cosmos, Rust, Golang, MOVE. They have experts in every direction I want to move into (pun
