Hopefully, the number of alts might drop if/when 2FA becomes mandatory. (And new users should have to employ 2FA automatically)
I do not think that 2FA will affect anyone operating alts. Different emails solves this and it is app base. I doubt different email solve when you could just use plus feature like this, example+1@example.com
example+2@example.com
example+3@example.com
In addition, email forwarding service let you generate "unlimited" email address such as https://www.33mail.com/. |

Nobody's bothered posting what Adam Back had to say about the situation, so here you go:  I'd rather not pay $9.67 (current high priority fee from https://mempool.space/) just to open LN channel when i don't plan to pay with Bitcoin frequently. And while you can exchange for Bitcoin located on sidechain (such as L-BTC and R-BTC), you'll need to prepare altcoin or fiat if you want to avoid high fees on Bitcoin on-chain. |

flexible block size were proposed, where the maximum weight is adjusted by demand or there are incentives to miners to adjust the blocksize carefully if needed.
This would be better than treating transactions differently, in my opinion. However, it has to be implemented similarly to how XMR does it. Raising the block size would result in a reduction in the block subsidy; otherwise, whatever the max cap is will always be activated by greedy miners. This would lead to larger pools absorbing all available well-paying transactions, leaving smaller transactions with almost nothing. --snip-- How about BIP 104, 106 and 107? Although personally i'd rather avoid dynamic block size altogether since there's concern it could be manipulated by miner who decide which and how much transaction included on their mined block. |

1. Windows laptop (as of now, easier for me)
Is a setup including a 16GB RAM and Intel Core i5 (12th or 13th generation) sufficient to run a node and do some data analysis (Python, SQL) simultaneously? I know it is not easy to answer such a question, but I would appreciate your opinion.
Probably yes. You can configure how much RAM used by your SQL database. And after you download all blockchain, you can setup Bitcoin Core to use less RAM as well without much problem. Just don't try to load all data to RAM at once. Or can I simply disconnect my SDD (where the blockchain data is stored) from my node for a few hours and download the blockchain data directly to my other laptop?
Yes, assuming you use Bitcoin Core to download blockchain data. Will it cause problems if my node is offline for several hours or does it just need some time to synch once it is online again?
It's the latter. 2. Rasperry Pi
I am eager to run one node on the Rasperry Pi for the previously mentioned reasons and to get more familiar with Linux. Accumulating knowledge and skills will take time but I am willing to invest the time.
I expect Raspberry Pi will struggle for data analysis. |

Namecheap is a good one. I have bought multiple domains, and a couple of hostings before, and I was never asked to verify my identity. I still use them to this day.
But take note their support page state they can ask you to perform identity and payment verification[1]. The same thing applies to Vultr, I never had any issues with them but I did see a couple of users here saying they did ask them for personal info before.
I also recall they require you to use credit card or paypal before you can pay with cryptocurrency. [1] https://www.namecheap.com/support/knowledgebase/article.aspx/10520/45/identity-and-payment-verification/ |

I'd just treat them as SEO spam. In addition, many of thread/reply they create are extremely similar. Anyway, i reported all of them and let's see whether moderator nuke them. Edit: Here's current report result. 2 Good, 1 Unhandled and 1 Bad. None of them got banned or nuked. If we want to see those user got banned or nuked, i expect we'll need separate thread which contain more detailed report/explanation. |

If you use the forgotten-password function, then there's an option to remove the 2FA. So 2FA does not provide any protection in case of a compromised email. Make sure that your email address is secure.
It somewhat limit security offered by 2FA, but i guess we could just set 2FA on our email address. In conclusion using the 2FA you have to be a kinda speedy because the code expires every minutes.
And that's just how app-based 2FA usually works. Hopefully, the number of alts might drop if/when 2FA becomes mandatory. (And new users should have to employ 2FA automatically)
Can we have a shield to indicate we have 2FA enabled, please?
Kudos.
Could you explain how mandatory 2FA leads to less alts? After all, it's app-based 2FA. |

Beginners and help board is sufficient. A member could just ask for ELI5, although it's up to other member how well they can explain things as simple as possible. Although for complex stuff or specific question, ELI5 doesn't seem to be possible.
This is what I thought would be the problem too, that it's going to be difficult to explain some of the crypto information like you're talking to a 5-year old, it's going to be difficult task especially if there's not a lot of people that are adept at that field and it's difficult to do it to those that will answer the questions and do the explaining because if they only have a surface knowledge, they're bound to have a hard time dumbing down the answers to make it easy for someone to understand and also there's the terms that are really difficult to explain like cryptospace, cryptocurrency, bitcoin core and many more. Yeah, it's very rare to see great simple explanation about new or complex topic ( an example for LN). Even those who somewhat familiar with the topic usually tends to use unfamiliar terms. Maybe just copy the answer of the other users to your questions and then paste it in ChatGPT then ask the AI to simplify it or do a prompt like this: "Explain this next sentence like you're explaining it to a five-year old kid." From there you can tweak the prompt to make specific requests to your liking.
It's rather controversial idea though, especially if you don't put discalimer that ELI5 comes from other user reply with help of ChatGPT. And without double-check and some re-writing (which takes some time), i expect mixed result. |

If your friend going to blame anyone, most blame lies to people and group who create and facilitate BRC-20 transaction. If the developer were to make Ordinals (which used by BRC-20) non-standard or even invalid, they'll take major risk where they accused to censor Bitcoin and some people ignore update released by developers anyway.

In a nutshell: Could malware move sensitive data back and forth between the usb and the connected computers without you being any the wiser?
While there are many malware which spread over USB storage was very common, i only recall very few malware which also move sensitive data/file over USB storage with goal uploading to creator's server. On the contrary - I think it is mandatory. A software level airgap will never be completely secure, since you are one misclick or one accidental setting change away from re-enabling some form of connectivity and breaking your airgap. A hardware level airgap (i.e. connectivity hardware removed) will always be a safer option.
The only "problem" with airgapping is that it must be permanent as you said. Therefore, it must be dedicated to always being offline, both hardware and software-wise. And the problem with this is that one must buy this device only to use it offline which renders it limited to a small amount of tasks. That's true. Aside from networking, you'll only use small portion of the storage and barely use the CPU/GPU. It's one of reason people also prefer to use their old PC or laptop. Raspberry pi is nice option. If you go for pi zero you may want to read about SeedSigner too. Using it as signing device is much more convenient than an offline computer imho.
Yeah this is exactly why I thought of using RPi Zero. The only problem is that I can't find any RPi Zero without WiFi (the non-W version). At least where I live, it's difficult to find. But if you can find W version easily, consider buying that and uninstall both WiFi and Bluetooth driver. |

I see OP edited his thread to add more clarification, so i decide to add new reply. >>This is not an issue with virtual environments, rather an issue with unreliable module compatibility.<<
In that case, why don't you ask people who create the module/library to pin required library to specific version. For example, >>A typical user is never going to resolve this, therefore any application released in Python must be considered non-production.<<
Typical user doesn't have to touch Python anyway. They should just run installer or portable executable which already contain all required file. Electrum already does that with installer, portable version and AppImage. |

Sir, the idea is that we are a new company with the same name, but we are not scammers. And why did you say you are back again? Have you been here before? We profit using advertisements and donations. Do you get the idea and we provide the service of creating a Bitcoin Wallet?
It doesn't matter. Given that your wallet is not open source, the addresses generated through your website could already be compromised (you have access to the private keys) The site has been developed from a new open source version https://github.com/OutCast3k/coinbin/This, sir, is an open source project, but we have developed the appearance only to add some ads Whether it's true or not, i'd rather use coinb.in since it's open source while coinpot dot cc isn't. |

Depends on the terms of service whether they are legal. Yeah, as it turns out, they are not very friendly with unauthorized sellers.  There are certain restrictions in connection with the use of Amazon.com Gift Cards. If you engage in these activities, Amazon.com may prevent you from claiming or redeeming gift cards, or may take further action on your account without a refund.
[...]
- Purchase a gift card from an unauthorized third party as we cannot guarantee that they are legitimate. But on other hard, how do we know whether a seller is authorized third party? I did quick search, but it seems Amazon doesn't show such list. - Are they legit or is this a usual financial instrument used to scam people?
It depends. With rate lower than one (e.g. you pay $95 to get $100 gift card), it could be either scam, obtained illegally or the seller simply want to get rid of their legit gift card. |

I couldn't find anything convincing but I found out that using the "send everything" option or "max" in some cases, reveals your entire Bitcoin holdings and it's true. But I still don't know how others will know that's your entire Bitcoin holding without the private key.
That explanation isn't detailed enough. If your Bitcoin comes from multiple sources or have different usage, "send everything" means everyone (primarily the source of your Bitcoin) know those Bitcoin belong to same person or group. Splitting into multiple transaction where each transaction comes from same source or usage would preserve your privacy better. Although with current mempool condition, you'll spend a fortune doing that. |

I just send the PM.
Honestly i have no problem with your campaign management. Although in case of ridiculous BTC mempool, would you consider Bitcoin sidechain (probably Rootstock or Liquid)in the future ?

Bitcoin core developers are most time anonymous and could leave and join at any time. There also exist organizations that helps in funding their activities.
By any chance, have you checked this article Who Funds Bitcoin Development?They still appeared when discussions on increasing Bitcoin block size is been discussed. Does that mean that through consensus Bitcoin core developers can make changes to the blockchain or does their control only end in the Bitcoin core.
Ends in Bitcoin Core. But it can't be denied they have relative big influence, although theoretically people could fork Bitcoin Core software. Bitcoin core maintainer's role still confuses me. Their role look similar to that of core developers.
IIRC it refer to maintainer's role on GitHub who can decide which commit or PR to be merged or not. Is there any group that checks and balance the activities of the Bitcoin core developers?
AFAIK no. But since their actively is done publicly, anyone can check what they're doing. |

Argument 2: "Increasing block size would lead to centralizing Bitcoin in terms of mining."
In theory, this holds true as well. The average miner would safely download or propagate a 4MB block but will have a difficult time handling a 40MB block. This means only large miners would survive, leading to centralization.
Counter-Argument: This is B.S. 99% of blocks are found by mining pools that spend thousands of dollars a month on operating nodes across the globe, running on a gigabit fast internet connection. They could handle a 40MB block just as easily as they handle the 4MB block.
In addition, block propagation become easier with existence of compact block where node doesn't broadcast whole block since most other node already have TX data on their mempool. It is not about storage. It is about verification time. I
Hmm i disgree, notice that i mentioned handling and propagating blocks only for miners, because for a non-miner node there is no "rush" to download or verify a block, storage is more important. But anyway, for a good hardware it takes about180 seconds to do all of this - Download a 2MB block - Empty some space if need -Verify all transactions -deal with the mempool and construct a brand new blocktemplate. A non-mining node doesn't need much processing for a block, and should be able to process a block size of a few hundred MBs in no time, this is only a sub-issue for miners not all nodes. But longer verification time means longer time to propagate block to most/all Bitcoin nodes. Pool and miner will waste more time/resource before their node receive newly mined block. And then, you have a problem, because if your ratio of verification time to the new block time is too high, then you can reach the point, when you never verify new blocks, even if all of them will be downloaded on your disk. Interesting thought. So, for instance, someone can attack BSV by simply filling the blocks with more than 600 MB data. I think their block size is 1 GB, so it is not a very expensive attack. (I do not know if anyone still uses that, maybe it is already attacked several times) I believe in past there was project about inserting weather data to BSV blockchain. There was also 2GB block which mostly contain duplicate dog image. |

More work needs to be done here. I do no want to say that I dont trust the exchange but if you feel like you have something to achieve, whether it be genuine or not, you should focus on leaving it neat enough without traces or suspicions. Imagine if I have to see a Russian write up for whats supposed to be an English audience, it is obviously not what you wished for that will play out. Thanks all the same for taking out time to work on the exchange
It's not worth the effort and praise, mate. The site is probably a scam if you take your time to read up the replies and findings above. I will be surprised if the OP himself comes back to this ANN to defend his scam because he has been exposed. If it's truly scam, then they couldn't scam anyone since their site currently isn't working where CloudFlare says "Connection timed out Error code 522". I guess nobody fell for their trick, so they don't bother check or maintain their website. |

Ordinals are a waste of block space but what can we do? miners just want profits and they'll mine blocks irrespective of what they contain.
Technically it isn't a waste in block space. It doesn't take the space from actual Bitcoin transactions. It's obviously wrong, Ordinals TX has size more than 0. Ordinals NFTs reside in the part of the block where witness data resides. They are prunable.
Aside from prune node which only store latest blocks, you still need to store UTXO created by Ordinals inscription. Ordinals (mainly BRC-20) popularity massive increase total UTXO where it already impact IBD (initial block download) speed for Raspberry Pi and other device with <= 8GB of RAM. |
