Let me know how hoarding works out for you. In my experience there are so many reasons to cash out or invest bitcoins in other projects that hoarding them starts to look like the slowest way to get rich. And if you're looking to get rich, there's no reason to take the slow lane.
Also, it may be the case that when bitcoin gets to $100, it may be because the us dollar has lost an inverse proportion in purchasing power, so you end up with the ability to buy as much as you did before. Lot's of starving millionaires in Zimbabwe.
investment in bitcoin denominated projects contains all the risk of bitcoin + counterparty risk + the project risk. So that a reason to save bitcoins rather then "invest" them.
If bitcoin will have gotten to 100USD solely due to inflation within the next few years, it will actually get to more like 10000USD because people will be running from fiat like its on fire. In a hyperinflationary world currency event the only money that will be effective for international commerce will be PMs or bitcoin.
But don't consider the above to be a prediction. Much more likely is sustained yearly inflation at < 20% -- that will do the job over the long term and keep society stable. Frog in a pot.
