I don't think that 1 btc is enough because if someone can collect 1 bitcoin, he will say that he wants more, and he will try to get more bitcoin. Everybody will have their own perception about how many bitcoin he will need to live comfortably, and maybe they will say that they want to have many bitcoin, maybe more than 10 btc. I will try to make more bitcoin because there is no limit on how many we can earn bitcoin in many ways. It depends on how we can get that bitcoin and convert it into fiat.
