Good question, is it fiction or reality? We need to stop and think about it, cause this question opens many others.
Yesterday I saw post on Twitter, someone with name Warren Buffet is making predictions about bitcoin, altcoins, and yesterday Twit is about bitcoin will be for saving, ETH will replace all smart contracts, and ltc will be currency. Now when I connect this two posts maybe 1 million dollars for 1 bitcoin is possible if all the people start to save in bitcoins, that is possible theoretically.
Well take my post with reserve, I'm just thinking out loud here. For me that price can be reality in the future, if all the things arrange in the right way.
