I think there is some kind of an intrinsic value to cryptocurrencies, it's derived from combination of energy and computational time spent on mining. Just as in your example with gold, energy could have been spent on creating something material and computational power could have been used to do calculations, but both were spent on mining coins, so now the value of those is a combination of 2 inputs, even though you can't get them back by disassembling.

However, this has really nothing to do with coin's market value,
