I think the idea is that you can invest a modest amount of BTC, wait a while for the world to realize the benefits of the technology, and then become part of the wealthy elite since the value of your stash of coins would have grown by then. It worked for the first generation of Bitcoiners, and it could work for us.

Say if someone had invested just $3,000 into BTC in October 2011 when they were going for $3 per coin. $3,000 isn't enough for someone to be considered part of the wealthy elite. But if they held onto their coins and sold when they were worth $1,000 each, he would have $1 million and therefore become part of the new wealthy elite.
