If it’s an online shop, I recommend using a Bitcoin payment processor that supports Lightning for the same reason of unbeatably low fees. My recommendation would be to use https://btcpayserver.org/. There are 'node in a box' setups. raspiblitz: https://raspiblitz.org/MyNode: https://www.mynodebtc.com/That do most of the setup for you in terms of setting up your own BTC node / lightning node / btcpayserver. For myNode, btcpayserver only available if you use premium version (cost $99) or you bother setup it by yourself. |

and he used " mycelium Wallet " on an Android phone to import the private key and send bitcoins - he did it all the time.
Is the Android phone still intact? Assuming it's not virus, bug or hacker fault, one possibility is Mycelium send remaining Bitcoin to change address (which generated by Mycelium). |

today i saw a new development in the lightning space: https://lightningaddress.com/tldr: send sats to the known email address format it is a combination of lnurl and a http server. some people who use letsencrypt might know the .well-known/acme-challenge endpoint to get certificates for your website. lightningaddress uses the .well-known/lnurlp/username endpoint to generate lnurl invoices According to the documentation, for all intents and purposes, you must be hosting your own email server in order to use this program. I assume you're referring to this image where the the website (domain.com) must return desired JSON response?  You cannot use popular email providers such as gmail (unless such email provider decides to offer this type of service in the future).
I agree, even email provider who accept Bitcoin is unlikely to offer this service. |

First of all, open Control Panel and check list of installed application. If Bitcoin Core is listed twice with different version, you should remove the old one and make sure the new one automatically run during startup.

Well here's the thing. BIP38 is going away. Eventually there won't be any wallets or any software that supports it.
It's literally available on many wallet, including hardware and multi-cryptocurrency wallet. Here's a hint, if they ask you to backup 12/24 words and mention it can be recovered on most wallet, most likely it use BIP 38. There are few competitor such as Electrum Seed Version System, but still can't beat BIP 38 even though it has versioning system and better security. Lucky for me though I was able to implement it in python 3.7 so I can use bip38 as long as I want to unless python decides to bullshit its users again like they did with the 2 to 3 upgrade.
Off-topic but... Python didn't bullshit its users. There was a long transition period where both were supported, Python 3 brings many needed features to the table like typing and is generally the better programming language. Maybe he's complaining about most linux distro had to drop lots of software which still depend on Python 2 or few software got discontinued since the author have no intention to convert it to Python 3. |

To be precise, you need to confirm 2 transaction. But IOTA community often refer it as PoW since it took few seconds to minutes (depending on decice you use). The goal of PoW on Bitcoin and IOTA quite different, where PoW on IOTA is designed to prevent/reduce transaction spam.
Then instead of a “blockchain”, it’s a “transaction-chain” with individual transactions using Proof of Work as a spam prevention mechanism. True, IOTA doesn't use blockchain, but DAG (Directed Aligned Graph). That’s not free
Their definition of free is not spending coin. and what are the incetives, plus what determines which transaction goes first? How to prevent reorganization of transactions?
I don't perform detailed research, so i don't know. But honestly i don't care since IOTA has single point of failure (see link i mentioned above). |

There are NO pages to be indexed. Yes, but by writing URL in a different way, it is possible to index some pages. There is no way for a bot to tell apart "topic/12345" from some forum page and "keys/12345" from that kind of calculator. For example, try searching "site:https://privatekeys.pw/keys/bitcoin/", you will see that some pages are indexed. "Some pages"? "Very few" might be more accurate since there's no way bot will index all of them. If the public key/address generated on server side, the server will crash or block the bot. But if the public key/address generated on client side, the bot will eventually crash, ran out of space or simply stop indexing the website (due to certain predetermined limit). |

Weird! I just realized that the warning message appears only when I click on the second link! Maybe it has something to do with the comment part at the end of the link! The difference between the first and second link is in the amounts and the added comment. The first one has a "Payment to Pmalek" comment while the second one has no comment at all. The obvious question to ask now is, does the blockchain wallet have a comments field while sending crypto? If it doesn't, maybe that's why the first links isn't recognized by the app. Even if the wallet doesn't support adding message/note to a transaction, the wallet could simply ignore the message on URI. It basically means Blockchain wallet made a bug when implementing BIP 21. |

You can also run android on it. Electrum for Desktop (Windows, Linux, Mac OS) have more feature than Electrum for Android though. Either way, it's on eBay now.
Sensible choice, considering there are many better single board computer. |

and he bought a second laptop to have multiple screens, just for crypto.
If people only need multiple screen, they would buy additional monitor which is cheaper than a laptop. So it's likely he bought it for another reason (for example, laptop dedicated to store Bitcoin wallet and other valuable data). My question would be: does he obviously hiding a lot of earnings from me in day trading, that he would do from Mars to December? Or is he legit to say he is just waiting all this time the good time to sell BTC when it will be a good time(with a new laptop just for crypto that he bought, not a expensive one, but anyway)
Without additional information, we only can say "we don't know" or make baseless speculation. If you want to find out the truth, force him to show proof from how the money is moved, where/when he bought Bitcoin and how he store the Bitcoin. |

Most mistakes are made by people reusing addresses but if we exclude that, and combine Tor, vpn and different browsers with mixers, that would be enough to break any possible connection between addresses.
Aside from what @o_e_l_e_o said, combining Tor and VPN have some privacy concern. Tor project made an article about it at https://gitlab.torproject.org/legacy/trac/-/wikis/doc/TorPlusVPN. Tor stops this by having NoScript installed automatically.
These days, it's only true if you choose "Safer" or "Safest" security option. NoScript on default security option ("Standard") only block few things. |

Electrum doesn't follow BIP39 standards
This part is important. It means you only can recover your walle t using Electrum and other software which support Electrum standard (formally called Electrum Seed Version System). Electrum also doesn't restrict the length (IIRC).
Correct, i just tried 500+ character as 13th word and it works. |

what do you think?
If another board for altcoin must be created, it should "Smart Contract" board which cover lots of technology/feature based on it such as cryptokitties, DeFi, NFT, DAO and many more. |

I do not know about mediafire, can you elaborate on the differences vs github?
Mediafire is an example, sites like that are for sharing any type of files including .exe files such as yours while github is first and foremost a "code" sharing platform even though it has no restrictions on file types being uploaded. You could just say uploading .exe to GitHub repository (instead of Mediafire or similar website) could give few people false sense of security (since few people treat GitHub as safe place to download software directly from the developer). Basically, it's in our interest to open-source the 64-bit random pool code so that Linux users can run it (you won't believe how many Linux users got nvidia cards attached despite the poor graphics support). I think the sensitive parts are limited to a few lines of code and variables, I'll see if we can just feed that information through a makefile and #define constants to hide those parts.
Alternatively you could provide AppImage file which should work for most linux distro. P.S. Nvidia GPU popular among Linux users becuase it offer better price/performance and exclusive feature (such as CUDA which frequently used on heavy computer science software). |

I wanna ask, is this the culture forum? A culture of bullying newbies.
No, this culture forum is sharing knowledge earning money through signature/bounty campaign. Also check https://bitcointalk.org/index.php?topic=5034141.0. Is this still a sacred legacy left by Satoshi Nakamoto? Why is it taken over by some tyrants and bandits? It's the biggest insult to Satoshi Nakamoto.
IMO Satoshi would be more insulted with KYC, Bitcoiner who only care about profit and effort to centralize Bitcoin. |

As far as I know newly created account have longer delays as compared to higher rank members. Or you could just use a simple google search instead. site:bitcointalk.org <keyword search> Google/DDG isn't good enough if you use generic keyword or keyword which have multiple meaning. In my experience, Ninjastic Space search ( https://ninjastic.space/search) produce far better search result if you know exact word, board, author or time-frame. P.S. I wasn't paid by anyone to advertise this service. |
