This seems to be the fundamental question of BTC:
How does a mining rig convert energy into a hard asset [that’s is, BTC]?
1.) What is the simplest explanation of the science of this blockchain technology? (Perhaps my question is worded incorrectly).
How does a mining rig “crack a code?” / mine to produce value?
2.) How does a BTC mining rig transfer BTC to a wallet? Especially cold storage?
