For each block successfully mined, the miner is rewarded with cryptocurrency. To ensure a steady supply, the reward amount is halving every 210,000 blocks (which roughly takes four years). As of October 2019, 18 million bitcoins out of the total 21 million have been mined.
Data exfiltration from such a computer is still technically possible but I wouldn't worry too much about it: btc you power that computer for a few minutes, turn it off, and you'll be fine. Use an airgapped/offline computer which has physically no network connectivity options (no wifi / no ethernet / no bluetooth / no nothing), no HDD, booted from, say, a live Linux CD with contains for example Ian Coleman's BIP39 tools. Then you enter your seed and verify that the extended public key / keys derived is the same as the one shown by your hardware wallet.
If this reoccurs during the next minimum, regional cooling may be slightly more impactful on those given regions, but it would still pale in comparison to the amplitude of warming from human-caused climate change. It's also worth mentioning that during the Maunder Minimum certain regions, like Europe, If you are you looking for more about BNB

As several miners verify several transactions at once, it is difficult for an attacker to hack into the blockchain and re-do all the work previously done. The more miners join and BNB verify transaction in the network, the safer it becomes.
From Bitcoin StackExchange : The term "on-chain scaling" is frequently used to exclusively refer to increasing the blockchain capacity by means of bigger blocks. However, in the literal sense of the term, it should refer to any sort of protocol change that improves the network’s capacity at the blockchain layer. These approaches tend to provide at most a linear capacity increase, although some are also scalability improvements .
Many alternative consensus methods are being developed to try and overcome this, and some cryptocurrencies may get rid of mining altogether. Although this current mining system helps to secure the network against attacks, mining requires expensive computer hardware that consumes a considerable amount of energy.
Mostly agree with your steps except that to sign a transaction, you need all of its data, not just the hash. So it would be impractical to manually type it in a hardware wallet (also, most hardware wallets don't have a keyboard).
This forces these miners to sell the BTC they earned via mining, often all at once, to keep the lights on, cash out, or to upgrade their systems for the future. This may sound relatively innocuous — of course, miners need to sell Bitcoin
to fund their operational expenses — though Garner noted that it becomes a vicious cycle, especially when profitability is limited.
Their chart implies that the sale of the $17 million stash only affected the price of BTC to a small extent, though the selling pressure may get worse in the coming days, especially as the "vicious cycle" that Garner depicted earlier has the potential to become reality.
Distributed mining power (hash rate) keeps the network secure. Hypothetically, the only way for Bitcoin transactions to be reversed is if the majority (51%) controlled the network’s mining hash rate. The more confirmations, the more secure a payment is considered to be. Provide security The more miners that are mining, the more secure the network is. Transaction confirmation A transaction is only confirmed as secure once it’s included in block inserted into the blockchain.
The blockchain scalability problem refers to the discussion concerning the limits on the transaction throughput a blockchain network can process. It is related to the fact that records (known as blocks) in the bitcoin blockchain are limited in size and frequency .
Each key is unique to each individual and is a way to link each transaction to the sender and receiver. This must be verified or signed in order for the chain of transactions to be validated. Digital signatures involve an encrypted code or ‘key’ that is attached to each transaction in the blockchain.

Once a miner has found the solution, they will share it with the rest of the network so that they can verify the solution and confirm the addition of the block. Miners race against each other to solve complex mathematical problems.
