Excuse me, could you please clarify if MobileCoin is currently available for trading or holding on the Coinbase platform? I've been hearing a lot about this cryptocurrency and its potential for mobile transactions, and I'm interested in adding it to my portfolio. If it's not on Coinbase, do you know of any other reputable exchanges where I could potentially find MobileCoin? Additionally, would you mind sharing any insights or predictions about the future of MobileCoin and its potential impact on the cryptocurrency market? Thank you for your time and assistance.
