There can only ever be 21 million people on this planet that will be able to hold 1 whole BTC. If you consider the large exchangers, early miners and whales (just the top 500 addresses hold 4 million BTCs alone, that's not counting the big holders who split into many addresses) I imagine the general public will only be able to get a hold of maybe maybe 8 million BTCs AT MOST. Of those, many will hold more than one. So, I imagine only 3-5 million people on earth will ever hold at least 1 BTC – ever. Considering 7 billion people, you're going to be one of the lucky ones.
