I don’t have and It is not mandatory for everyone to have the full 1 Bitcoin.  He buys and holds bitcoins according to his ability. Very few people own 1 whole Bitcoin because Bitcoin has a limited supply. And whoever owns 1 bitcoin can own huge amount of money if he holds it for 8-10 years.  Because 1 bitcoin = millions of dollars can be released.  Because its supply is low, but as Bitcoin spreads across the world and is used for various purposes, its value will increase exponentially.
