It might have been a bad day for the speculators and the gamblers, but it had absolutely no impact on Bitcoin.

I'm going to the Bitcoin 2021 Conference in Miami. Who else is going?
Day 1: the line to get in is literally a mile long

Americans travel about 2.2 trillion miles per year and a Tesla car uses about 250 Wh/mile.
If every car in the U.S. is replaced by a Tesla, then electric cars would be responsible the the consumption of 550 TWh/year. That more than the entire country of Germany uses! Obviously, we need to ban electric cars!

The double-helix pattern was probably caused by two instances of the Patoshi software/hardware running in parallel. We don’t know if this was a mistake made by Patoshi or it was intended for testing an improved mining setup. But the timestamps between blocks of the two Patoshi lines of the double-helix do not show the same delta distribution, as if internally, maybe due to physical proximity, there was no delay between blocks. Still it’s possible that Patoshi just turned off his mining equipment for about 5 minutes after mining a block. Is that plausible? How can we explain the differences in timestamp deltas?
Why is it assumed that the two instances are run by the same person? The second starts 3 weeks after the first, so could it be a second person with roughly similar hardware? |

Restricting your pool to miners that can prove their electricity is from renewable sources will only ensure that the pool is small. It won't prevent miners who can't prove it from joining a different pool or even making their own pool.
BTW, how many miners can control the source of their power? If you get electricity from a distributor then you can't guarantee that the power is from a renewable source.

Citing Reuters "Bitcoin production is estimated to generate between 22 and 22.9 million metric tons of carbon dioxide emissions a year, or between the levels produced by Jordan and Sri Lanka, a 2019 study in scientific journal Joule found."
That is a distortion of the facts. Bitcoin mining burns no carbon and produces no CO 2. Bitcoin mining is 100% powered by electricity, just like Tesla's electric vehicles. |

Bitcoin's energy use is not necessary going to keep growing at a fast rate, after a few more halvings more and more block reward would be coming from fees rather than new coins. Right now Bitcoin's energy consumption strongly depends on Bitcoin's price, in the future it will depend on on-chain transaction volume.
Not necessarily. The cost of mining is bound to decrease with time due to increase in the efficiency of ASICs... That's a common misconception. Efficiency has no effect on the cost of mining because of the economics of mining. The cost of mining a block approaches the value of the block reward, regardless of the efficiency. Increasing efficiency only increases the difficulty. |

That constant is used only for validation. It is not used to limit the number of coins. You overlooked the comment that immediately precedes the line you quoted: But, if it's used for validation, doesn't it also limit it too? If you change the block reward and leave that field same, will you be able to bypass the 21 million? It's uses don't affect the limit. If the limit were increased, its use for validation might be impacted, certain valid transactions might be rejected, and certain tests would be invalidated. Note also that the actual limit is not (and has never been) exactly 21 million. |

You hear it in every video of someone explaining Bitcoin. Isn't it more accurate to say that the reward will keep halving so that there will never be more than 21 million bitcoins?
Sure. That is more accurate, but "'Satoshi set the total supply of bitcoins to 21 Million' is nonsense" is hyperbole. Or as expressed in your terms, your title is nonsense. ... there is a line that limits the units to 21,000,000 on amount.h: static const CAmount MAX_MONEY = 21000000 * COIN;
That constant is used only for validation. It is not used to limit the number of coins. You overlooked the comment that immediately precedes the line you quoted: /** No amount larger than this (in satoshi) is valid.
*
* Note that this constant is *not* the total money supply, which in Bitcoin
* currently happens to be less than 21,000,000 BTC for various reasons, but
* rather a sanity check. As this sanity check is used by consensus-critical
* validation code, the exact value of the MAX_MONEY constant is consensus
* critical; in unusual circumstances like a(nother) overflow bug that allowed
* for the creation of coins out of thin air modification could lead to a fork.
* */
static const CAmount MAX_MONEY = 21000000 * COIN;

I have many aws ec2 VPS. Please let me know if I can do mining and can make some money. Your help will be appreciated.
Mining Bitcoin on GPUs has been obsolete for several years now. Even with thousands of free instances, it wouldn't be worth your time. |

I don't know if there is a uniform definition for a "Bitcoin Transaction Graph". You can represent transactions as a graph in many different ways.
However, I think that the most accurate graph would be a DAG with transaction as nodes and outputs as a directed edges between transactions.
You can convert the graph, turning outputs into nodes and transactions into edges, but then a single transactions could be represented by multiple edges. In this form you can group output nodes into addresses and wallets, though it would no longer be acyclic.

I just realized that my 50 BTC donation to the forum is now worth $2.9 million. Wow! Never in my life have I expected it to be that big.
WTF?  You don't consider the disappearance of your depositors' 4100 BTC in 2013, now worth $238 million, your "bitcoin pizza moment"? |

I am solo mining with my own blockchain and wallet hosted by me, I have opened the firewall to allow inbound connections, not just outbound, I figured it may be relevant in the off chance of success.
To answer your original question about connections, you want as many connections as possible. Also, getting on a relay network will help. You want to be mining on the latest block as soon as possible and you want the major miners to start mining your block immediately. Read this: https://galaxsis.com/posts/bitcoin_relays_part_1/ |

Does the number of inbound and outbound network connections to your blockchain play any role in who is awarded the block? For example, if a solo miner solves a block and then say 1 second later a large pool solves the same block before all the nodes record the block in the blockchain? Who wins? That's called an Orphan race. Which found block is confirmed first wins. So yes, connections matter but not how exactly many you have but rather how fast of a connection they have to the Bitcoin network so their found block is available to be confirmed. If by "confirmed" you mean another block follows it, then yes. The block that is first to have the next block built on top of it wins. Of course, the earlier block has a head start, but it is not guaranteed because the chain follows the longest branch, and the later branch could get lucky. And, if the next blocks are produced at about the same time, then it is the next block that determines the winning branch. And so on ... |

- A hot wallet is associated with the web and can be gotten to whenever.
- A chilly wallet isn't associated with the web and permits to store your assets disconnected. You can in any case get assets whenever, yet nobody can move them out.
Your definitions are lacking. A hot wallet is a wallet on a device that can be accessed through the internet, whether is it is hosted by a website or it is an app on a phone or a desktop. A cold wallet is a wallet on device that cannot be accessed through the internet. Examples are air-gapped devices, and paper and hardware wallets. Note that even though a hardware wallet connects to an internet device, it is considered to be a cold wallet because the keys are not accessible. |
