It's a really bad idea to try to get all of whatever people are using as money. How cool would it be if all dollars, paper and electronic, were teleported to me right now? Not cool at all; no one would have any and no one would use them as money anymore and I'd only get their use value, which is as uncomfortable toilet paper.
There is no incentive to get all the dollars or all the bitcoins. Some people talk like that, but I can absolutely guarantee you that when they get halfway there they'll be a lot more motivated to get enjoyable objects instead of more digits.
