Okay, I was just thinking about bitcoins and how amazing they are. Then I realized that it is inevitable for the price of bitcoins to go up over time, because as each person decides they will accept bitcoins the overall network effect increases. As the population of the world is increasing, so too must the price of bitcoins. I look forward to the amazing world we will build together using this wonderful technology.
I highly doubt very much, that there is an 'amazing world we will build together' using bitcoins.
Bitcoins are just another way of using money is all. If bitcoins ever level off more, then they will become just as boring as any of the currencies. Perhaps the hope of huge percentage increases, if a person bought lower, might be what you mean?
But if so, then why don't you consider buying into some of the so-called 'alt-coins', and those coins are much less expensive than bitcoins, with perhaps much larger percentage increases for some of them coming in the future.
The problems surrounding money in the past will continue with bitcoins as with other forms of money.
The bible says that money is the root of all evil.
