Correct me if I'm wrong — but couldn't this simply be done in the wallet side of things? As it's mostly just moving of decimal places anyway.
You are right. As we all know, each bitcoin is divided to 100 million units and there are 8 decimal places for bitcoin. You can send 0.001 BTC and your wallet or block explorers can show that as 0.001 BTC, 1 milliBTC or 1000 microBTC. But in the bitcoin protocol, there are no decimal places and we always deal with satoshis. |

But will that be a hard fork or a soft fork?
Since we have to change the consensus rules for that and it's required that all the nodes accept the new rule, it would be a hard fork. I thought anything that does not lead to creation of another coin is just a soft fork, I mean pertaining to this? Or will bitcoin blockchain be abandoned for a new one because of this?
Any upgrade that is not backward-compatible is a hard fork. As I already said, for increasing decimal places, we have to change the consensus rules. Nodes are free to not accept the new rules and have a separate chain. So, it would be a hard fork. |

Would such need to use smaller denomination units (smaller than satoshi) require a hard fork? Can someone shed some light into it?
Yes. For adding more decimal places, we have to change the consensus rules and a hard fork would be required. According to consensus rules, the amount field in a bitcoin transaction must be an integer between 0 and 2100000000000000 and we can't send 0.1 satoshi or 0.01 satoshi. |

His concern is: what happens if you have two transactions which have absolutely no connection but produce the same TXID? And the answer is that the second will be rejected, because of the BIP 30 soft fork. To be more accurate: The second transaction will be rejected if the first one hasn't been fully spent. If the first transaction has been fully-spent, we can have a block including a transaction with the same ID as that fully-spent transaction. |

But if I extract the private keys of all 7 addresses and individually load one by one address then server will not have any knowledge that all 7 addresses were a part of the same HD wallet.
To add to o_e_l_e_o's reply: It's also needed that you generate your seed phrase and extract the individual private keys (and addresses for watch-only wallets) on an offline device. If your HD wallet has connected to a server, your privacy has been already compromised. How the online existed blockchain already figured out the wallet address belongs to an offline wallet that is already created?
The blockchain explorer can't know whether your address belongs to a hot wallet or an offline wallet at all and if you use TOR connection, they won't have any way to link your addresses to your IP address. But if you search for multiple addresses in a block explorer in a short time, they may conclude that there's a connection between those addresses. |

My question which perimeters will tell them the addresses belongs to the same person, if it's not the IP history or master public key? In a HD wallet I can not even tell two addresses are from the same wallet if the address formats are same.
Let's say you have created an HD wallet and have generated 20 addresses. For getting the transaction history of these 20 addresses, electrum sends them to the server and the owner of the server will know that these 20 addresses belong to the same person. If you want to protect your privacy without using your own server, you can create a separate wallet for each of addresses, connect to different servers and use a new TOR circuit for opening each of wallets. |

|
|
Based on the IP of the broadcasted transaction or anything else like from the input address they can find the master public key and know all address of the HD wallet?
With using TOR connection, there is no way for the owner of the server to know your IP address at all. But they can know that the generated addresses belongs to the same person. They can't know your master public key, because the addresses are derived from the master public key locally. |

In electrum, you connect to the servers provided by other people and it allows you to choose the server manually. If you want to protect your privacy, you should download the full blockchain and run your own server and use TOR. If not, I would like to know if there is a way to check the balance of an address using the btc network and not a blockchain explorer, for example with some node calls running btc core. You can create a watch-only wallet in electrum just using your address. |

Hey Google, let the owners of 18CxzMfmadEvjwPjW8uzFe5n6xBDeraoJ6 and 1AmwSjzv6H3ujR7rFuVXLNz1yJfnJt2TFA find this topic!
There's another address in that transaction too. 1AhgYZ7Js6ytokA4zCD994MJJbpFsCUd61 And there are probably more victims. OP's fund was sent to bc1qtjt2qa2pghrea2xv5fwn0t6a7gmrc4f2238rnr in this transaction and then to bc1qhwppsmswazl9pghsq9k4v7jy502cvlwjqr34hk in this transaction. Therefore, bc1q87jd5xfq6xypy9tx6ssfhynq0e5z99u8whnuvp and bc1ql5cz9yp23ggdz2tjhmj3hkr37wula3u34sa30e are owned by the hacker/thief too. If you check the history of these two addresses, you see that the same thing as OP has happened to 1P4o7U7tDsxeHVhRPRMFgmrmaFhGxRmjQx and 19fikpWsuxRnqQqrgnSWvVETvQHRMa9a3k. |

Somebody I know made bets on the price in 15 second intervals and feels he got cheated. So now we are trying to reconstruct the evidence with the actual exact seconds prices.
Binance allow to set the time interval even to 1 second, but if you want to know the exact price on a certain second, take note that it may vary from exchange to exchange. So, you should know which exchange or price tracking website was used as the reference. |

I wrote to their email address, can I write somewhere else? Link please
TheQuin is their representative and is active in this thread. Wait. He will probably reply to you once he sees your post. But as a newbie, i don't think you can DM anyone so you would need to grow your account a bit for that.
Newbies can't send personal message only if the receiver has unchecked "Allow newbies to send you PMs." in "Personal Message Options". By default, users should receive message from the newbies. |

To put it this way: a Bitcoin transaction, even if 90% of Bitcoin miners consider it "malicious" and deny to include it to their candidate block, will at some point in the future be confirmed by that 10% left, because they upload blocks as well.
If 90% of miners agree with censoring transactions, it's possible that the 90% don't add any block to the chain including blocks mined by the 10% and since their chain will be the longest chain, the 10% will have to join the 90% to have a profitable business. Of course, I don't think this will ever happen. |

Maybe the option wasn't there back when you tested it out. Maybe they added it later or you forgot to activate the advanced options.
I just tested it. Bluewallet allows you to add a passphrase to the seed phrase only when you import a seed phrase. It doesn't allow you to add a passphrase to the seed phrase when you generate a seed phrase. Have you tried generating a new Blue Wallet native seed, delete the wallet, and then recover that same wallet from seed with advanced options enabled to get to the part where they allow you to add a passphrase?
This is the only way to have a wallet with a seed phrase that has been generated by bluewallet itself and extended by a passphrase. You should generate a seed phrase in bluewallet and then create a new wallet with importing that seed phrase and entering your passphrase. |

It's the first time I heard about a mobile wallet providing this kind of feature. It should be a primary criterion though, since several mobile wallets have been hacked because of their lack of entropy in the past. On which form could we enter entropy? Only base 6 numbers(dice) or decimal, binary and hexadecimal values are also accepted?
In bluewallet, you can generate a seed phrase with entering your own entropy manually. The entropy source can be a coin flip, a 6 sided dice roll or a 20 sided dice roll. For more information on how to create a wallet with providing manual entropy on bluewallet, click here. |

But it doesn't matter, because they all predict the same, I think.
No. Since different websites may different methods for estimating halving date, they may give different dates. For example, the website you mentioned predicts the halving to be 500 days later while buybitcoinworldwide and coinmarketcap predicts it be 480 days and 522 days later, respectively. |

The official Bitcoin Twitter page has given a countdown to the Bitcoin halving on what the Bitcoin market will look like in the future.
The official bitcoin twitter page? Take note that there is no official account for bitcoin on twitter, just like there is no official bitcoin website. Since bitcoin is a decentralized system, it's impossible to have an official website or an official account on social media platforms. |

We can't be certain if theymos is controlling bitcointalk twitter account or not,
That's the official account of forum on twitter and is controlled by theymos. Read the old post made by him. Twitter @bitcointalk is official, but I only use it for outage notices and such.

How would you recover your wallets having lost S1 and P2 or S2 and P1?
If you have lost S1 and P2, you still have S2 and P1. If you have lost S2 and P1, you still have S1 and P2. Since S1=S2 and P1=P2, you actually have the seed phrase and passphrase of your single-sig wallet and you can easily recover it. |
