I am trying to understand how the mining process works. I haven't ever mined, so I would probably understand it if I mine (maybe using zcash or another crypto that is starting). I understand the overall how the process of mining works, but what happens with the coins that a miner earns? Like, if I am a miner and I earn some coins after resolving the problem, where do all the released coins go? Do they all go to the miner? If so, can the miners hoard all the coins for themselves and not share them the rest of the world?
