Dive with Alice into the mysterious and controversial world of cryptocurrencies. We are on the eve of Covid confinement when the young woman received an inheritance from her grandmother and wonders what to do with this money that her banker wants to invest for her. By chance, she discovers that parallel currencies open the door to another world. Misunderstood by her family and friends, she nevertheless threw herself into it wholeheartedly. Her online comics on her experience make her quite the influencer, explaining crypto’s intricacies in simple terms but with eyes wide open as to its dangers. We even travel with her to El Salvador, the first country to accept Bitcoin as a national currency, and its cryptocurrency farms, to understand the power and perils of Bitcoin, NFTs, blockchains and other curiosities.
