If you'd like to hold BTC for 10-20 years, they may be quite cheap at the moment, as most of them have already been made. Just over half have been mined at thi

  But they are getting exponentially harder to make.

    They are made at a constant predetermined rate. They are only harder to make because more people are trying to make them. The way bitcoins work is that the difficulty of the proof scales with the CPU power. If half the computers currently mining decided to move on to do something else tomorrow, bitcoins would continue to be made at the exact same rate.

  On a log plot, half and one are very close together. In my view, this is the way to look at BTC: http://bitcoincharts.com/charts/mtgoxUSD#tgSzm1g10zm2g25zvzl http://bitcoincharts.com/charts/mtgoxUSD#tgSzm1g10zm2g25zvzl BTC has only just begun to experience volatility. The natural price is somewhere between $10^7 and $10^-7 (I'd pay $1 to own all the BTC, just for kicks). The future will sort it out. For as long as coins are still being made, there's direct connection to reality. Someone, somewhere, will have a few integral BTC, and they'll probably want to exchange them for something else of value. After the coins run out, I can't figure out what happens; it might be bad.
