I do not want to give the wrong idea about the possibility. But, consider that not all of the 21 million have been mined, how many of the 17,819,550 (according CMC) BTCs do you have? IMO there is enough amount for you in the exchanges. On the other hand, as friends have pointed out, BTC doesn't have to be 1, but if you see it as 0.000000001 BTC, there's more than you want.
