Online user base companies need users to grow. you think the game needs to improve in order to get more users (I agree but unlike you I won't prioritize BB work)
Such companies such as BuzzerBeater can get more users if their user value increase. User value is determine by how much money each user is worth.
My suggestion enable BB to increase user value which will enable BB to get more users if they will like it.
I must say that virtual currency is not a simple business model, not a lot of companies successed in it, but it might work.
This requires some real research from BB in case they will think about it.
