so. even in the most extreme case equal distribution of bitcoin among all people on earth is quite resanable and 1* ten to the sixth power USD per BTC looks alright. all we need is a mechanism of equal distribution/
I'd say it is quite an interesting topic and I like the idea of giving charity or donations. However, I don't think Bitcoin will be a good tool to make it happen because first of all, not everyone has access to this cryptocurrency like Bitcoin so even if you allocated it equally I still don't think everyone will benefit from it. There's a possibility that it might just sit on their wallet and not use single any of it. Perhaps if you will plan to have a kind of charity like this one using FIAT would be much appropriate.
