The OP's ideal looks crazy but i think it's can be real in the future. When everybody is chasing for bitcoin and the amount of Bitcoin is limited which is less day by day . So It's easy to understand why price of Bitcoin raising insane in the future.
To be honest, anything is possible and I think that we should not discard any idea or prediction in this regard. Especially in the case of the wild market such as cryptocurrencies.
We have predictions right from $1000 to $500,000 till 2020 and everyone has their own point of view. We must realize the fact that no one can predict the accurate future, all we can do is to predict the possibilities considering the available data and since Bitcoin is a global phenomenon, we have multiple possibilities and views for the same.
