Late one evening, Olivia, a software engineer, received a frantic call from her friend Max. He had invested his savings in a new cryptocurrency called "LunaCoin" after reading about it on an obscure forum. Max was ecstatic when LunaCoin's value skyrocketed overnight, but his excitement turned to panic when he couldn't access his digital wallet. Olivia, ever the tech-savvy problem-solver, rushed over and discovered that Max had been phished by a fake support email. They spent hours recovering his account, narrowly escaping disaster. Max learned to be more cautious, and Olivia earned the nickname "Crypto Guardian" among their friends.
