How the mined bitcoins come from the coinbase tx into the miner's pocket. I.e. it's said you can get the so called "vanilla coin", however, there anyway few other tx hops to get the reward. How different pools payout your subsidy? Do you need registration? What about subsidy via lightning? How much non-KYC mining really is? (Hosting and ownership of miners, pools, IP addresses, etc.). What about security, miner remote hacks, dos attacks?
