I believe in crypto. It is the tech for 21st century+ value exchange. Gold, well, try to pay a coffee with it, or try to trade a bag of potatoes in the gulag with it (you will succeed, until hunger(sum potato mass) > sum gold hunger...). Sad facts of life.

If we have almost unlimited energy (near the output of the Sun), all molecules can be fabricated (such as gold). But re-calculating more than 6 blocks of bitcoin transactions would require more energy (entropic status) than our Sun produces in a week. (there is a physics prof who actually made that calculation )

So gold would be a millionth time easier to reproduce than bitcoin in the future, so i bet on btc.
