I am a traditional art collector and recently registered for an upcoming online contemporary art auction. To my surprise, the organizers announced that several exclusive digital art pieces can only be acquired using blockchain-based tokens instead of standard bank cards. I have zero experience with this type of technology and do not possess any digital assets or a secure place to hold them. The auction starts in a few days, and I am searching for an Android application that can help a complete novice like me acquire these assets safely. I need a clean interface that does not require advanced technical skills to understand, as I just want to participate in the auction without making mistake
