We all know that 0.1 or 0.01 BTC in the long run will represent a significant amount of money (in dollars). What do you think could be a coin with incredible value in the future?
Its a balance IMO, if the FIAT value voes too high it becomes risky to physically
move it and could end up swiping the load and selling the coin.
There are so many coins out there which are going to fetch handsome premiums,
they have all been mentioned. Things are different now from when Casascius
started. I think a lot will be determined by the load in combination with the mintage
along with condition and grading
