Let's say you run Line. Your messaging service, plus other forays like smart speakers and music, aren't enough to avoid substantial losses. What do you do to turn things around? If you ask the company, finance is the answer. Line has created a new financial company that will offer cryptocurrency trading on top of staples like insurance and loans. It's not saying what currencies will trade or when the virtual money service will be an option, but it plans to make all the services available within the Line chat app.
