Other than that, I am wondering where is iwantmyhomepaidwithbtc2 our friendly new gang member which wants to buy a second village with BTC. I did not see him in a while...
Thank you for the image link dear Gazeta I just got back from vacation! I was using an inconvenient way to post on the forum so I posted very little. Here is the first translation posted in the FR local board : Il y a 2^256 clés privées : de quel ordre de grandeur est ce nombre ?
Working now on the next ones

Auteur : fillipponeTexte original : There are 2^256 private keys out there: how big is that number?
Hier, alors que je surfais sur internet, dans le puits sans fond de sites liés à Bitcoin, je suis tombé sur le tristement célèbre site web keys.lol https://keys.lol(Attention : c’est une perte de temps !) Il s'agit en fait d'un site web qui génère aléatoirement 128 clés privées sur chaque page, puis vérifie le solde des adresses associées (compressées et non compressées) sur la blockchain en signalant d'éventuels soldes positifs ou des transactions passées. Wow! Si vous trouvez un solde positif dans ces pages générées, vous serez en fait le propriétaire des clés privées, vous serez donc le propriétaire légitime de ce solde, et rien ne vous empêchera de le transférer vers votre propre portefeuille. J'ai passé quelques heures sur ce site, générant des milliers de clés privées, bien sûr sans rien trouver, pas une seule adresse utilisée, et encore moins une adresse avec un solde positif. Ensuite, j'ai commencé à penser que je pouvais améliorer un peu le processus, et en discutant avec d'autres utilisateurs sur le forum, j'ai pensé que nous pourrions avoir un script générant des clés privées aléatoires, puis demander à notre propre nœud bitcoin le solde dans ces adresses et finalement transférer tout solde trouvé dans nos propres porte-monnaies. J’ai pensé que le fait de travailler en local devrait accélérer un peu le processus. Je savais dès le départ que les possibilités de trouver quelque chose étaient infimes, mais je voulais essayer parce que chercher des soldes et ne rien trouver me rassurait sur le fait que personne ne pouvait faire la même chose avec mes propres bitcoins si jalousement conservés dans mon propre cold-wallet. En attendant que @babo divulgue son script, je me disais “Fillippone n'est qu'un pion dans la vie”… Comment personne n’a pu y penser avant ? De retour dans le puits sans fond, j’ai rapidement fait la découverte du “Large Bitcoin Collider“ (le Grand Collisionneur Bitcoin). https://lbc.cryptoguru.org/aboutWow c’est un projet sérieux. En gros, des milliers de serveurs distribués génèrent et vérifient 26 trillions ( !!!) de clés privées chaque jour. Au cours des trois premières années, ils ont réussi à trouver 7 clés privées. C'est beaucoup ! J'imaginais que les chances étaient beaucoup plus faibles, mais il y a probablement un bug dans certains portefeuilles qui utilisent un générateur de nombres aléatoires non-optimal pour créer des clés. (Des recherches plus poussées s'imposent ici !) Passons rapidement en revue quelques chiffres : Nombre de clés privées théoriquement possibles : 2^256 soit environ 10^77 Nombre d'adresses Bitcoin : 2^160 Nombre de clés privées recherchées par le collisionneur : 2^160 Nombre d'atomes dans l'univers : de 10^78 à 10^82 Nombre d’ adresses Bitcoin utilisées : 18,000,000 Le nombre de clés privées réellement possibles est légèrement inférieur à 2^256, comme spécifié iciPrenons quelques exemples. - Supposons que nous ayons un milliard d'adresses actives, chacune d'entre elles ayant un solde positif : nous savons que ce chiffre est environ 10^3 fois plus élevé que le nombre réel.
Le nombre d'atomes dans l'univers est probablement 10^3 fois plus grand que le nombre d'adresses, de sorte qu'il est juste de dire que trouver une clé privée avec un montant positif est à peu près aussi probable que de trouver un de ces atomes répartis dans l'ensemble de l'univers visible. Quelle est la taille d'un milliard d'atomes ? Selon cette réponse de Quora, c'est plus petit qu'une bactérie E.Coli. Imaginez donc que vous preniez cette bactérie, que vous la déchiquettiez au niveau atomique, que vous la répartissiez dans l'univers et que vous essayiez de trouver l'un de ces atomes. Plutôt difficile, n'est-ce pas ?
- Prenons un second exemple tiré de cet article. Supposons que nous voulions scanner toutes les clés privées à la recherche d'un solde positif et supposons que chaque habitant de la terre ait une vitesse de balayage un milliard de fois supérieure à deux fois la puissance de calcul actuelle du réseau Bitcoin, donc :
* 10 milliards de gens ; * multiplié par un milliard ; * multiplié par le double de la puissance de calcul de Bitcoin, soit environ 100 000 terahash par seconde ; On obtient : 1,000,000,000,000*1,000,000,000*100,000*100,0000,000,000 = 10^10*10^9*10^5*10^12 = 10^36 Pour simplifier, nous arrondissons à l'unité inférieure ‘115,792,089,237,316,195,423,570,985,008,687,907,852,837,564,279,074,904,382,605,163,141,518,161,494,336’ à 10^77, et nous obtenons que, si nous vérifions chaque clé privée, à la recherche d'un solde positif, cela prendrait 10^77/10^36 = 10^41 secondes ; combien d’années cela prendrait-il ? Sachant qu’il y a 31557600 secondes en une année, cela correspond donc à 10^41/31557600 = 31^33 années, qui est plus ou moins 10^23 fois l’âge estimé de l’univers (actuellement estimé à 13.82 milliards d’années), en gros 100,000,000,000,000,000,000,000, soit 100 milliards de milliards de fois l'âge de l'univers.

If this person is not disgusted after a bitcoin hack or crash, he/she must face:
- New words that correspond to unfamiliar concepts. - Tons of cybersecurity tips (mail protection, 2FA etc...) - An anxiety-provoking environment that talks about hackers all over the place. - Tools such as hardware wallets which seem complicated when some people already have trouble using a computer.
It's very true, Bitcoin (like all cryptos in general) suffers from excessive mystification, even though it's fundamentally not complex to use. As the few feedbacks from the adoption of BTC and LN in El Salvador clearly show, a simple wallet, with an effective UI, seems essential if we want users to head away from a CEX. I think there are more factors involved, and there are (almost) as many reasons for CEX users to store their BTC on a CEX wallet as there are CEXes users. For example, large CEXs are translated into many different languages. For non-English speakers, this is a real advantage; most of the documentation, videos, and explanations found through quick (I mean non-deep) researches are in English in general, and I think CEX may also seem simpler to them from that point of view. That's why I like so much the Local boards concept on Bitcointalk for example, we need to have good documentation in as many languages as possible. There's also the fake sentiment of protection that CEX offers, a bit like 3.0 assistance. As you wrote, many people are aware of the risks associated with self storage (such as loss of private keys, unsafe backup, etc.), but they think little of the risk of having their personal data stolen in the event of a CEX hack, and so use the service without being fully aware of the risks involved. I'm like you, I only use P2P whenever possible, I avoid KYC and centralized platforms. However, wondering why people prefer Binance to Bisq or Peachbitcoin is like wondering why they use Google rather than Duckduckgo, why they use Gmail without PGP rather than privacy-focused services etc.... Answer ? Probably convenience, laziness, lack of knowledge, fear of learning things unknown at the moment... Plus those who are in it for the fast money only and aren't interested in the essence of Bitcoin will always be CEX users. I ended up changing shitcoins into btc and putting that on a hardware wallet (but not the ledger whose interface I don't like). Finally I applied the maxim "not your keys, not your coins"). Maybe that's the beginner's path after all? Going slowly towards this goal, without being too greedy or too naive and doing things at your own pace (I'm particularly slow I think...)
It's better to take things slowly, leading to a solid foundation and knowledge, than to be hasty and immature, especially when it comes to crypto and money

Au final, je vois pas trop ce que ça change, à partir du moment où le HW wallet est protégé avec un code suffisamment fort pour avoir le temps de réagir en cas de vol/perte.
Et même dans ce cas ce n'est pas trop le stress, le Ledger (en tout cas le Nano S) se réinitialise après 3 mauvais codes pin entrés. Donc à part pour ceux qui choisissent 1234 ou 0000 ou leur date de naissance, y'a peu de chances qu'un tiers puisse le déverrouiller en moins de 3 essais. Partez vous en vacances avec votre ledger ?
Je voyage beaucoup avec mon Ledger, parce que je ne sais jamais pour combien de temps je serai parti. Mais si c'est pour des vacances de deux-trois semaines je ne m'emmerderai pas à le prendre avec moi. Certes mais si une catastrophe se produit (par exemple un violent depeg de l'usdt), on ne peut qu'être spectateur de la tragédie.
La question que je me pose est plutôt : si l'usdt depeg pendant tes vacances, serais-tu au courant ? Perso pendant les vacances je ne surveille jamais les cours et les actualités crypto, c'est le vrai but des vacances aussi

I heard most Asic miners problem is from the power pack, I wish I can learn how to repair them myself, all I can fix are electronics since I learned the work at a young age, I know diodes, resistors and others and I also know how to use a meter to detect faults but I am sure it's going to be different with Asic miners.
If you're interested, this link contains courses on basic ASIC repair. There are also courses dedicated to each ASIC model, but these are not free. https://course.zeusbtc.com/asic-miner-repair-courseHappy hashing !

I'm in Europe, and I thought, "Great! I'll be able to avoid some taxes!" So I took a look at your reputation. As a result, I'm thinking of keeping my Shenzhen contacts for ordering ASICs, and paying taxes instead, which seems less risky to me. With this kind of reputation, and prices that I find very high, I'd rather pass. Examples of feedbacks related to your shop : Comprehensive MineShop Review:
Transaction
Hardware The rig comes pre-installed with ethos which I erased and installed Ubuntu instead as I am more familiar with that distro. The rig that arrived was different to the specs I had ordered on the website, I ordered 6 MSI 470's 120GB 8GB fury ram. What arrived was 6 MSI 580s 16GB SSD and 4GB of cheap ram. I have no issue with this really as I will be mining Electroneum mainly but should I want to change my mind and mine Ethereum instead I would have to upgrade the SSD to allow for the huge DAG file Ethereum has. I would say that the hardware may have been used for mining prior to being sent. The rigs come with wooden supports under the motherboard which is to stop the board shorting on the metal frame, they're unpainted so are very contrasting to the rest of the rig. My rig has been working without issue for about a week, so the hardware they sent to me is in good working order.
Support I tried to contact MineShop to confirm the different specs (to see if they had made a mistake) but they did not seem to understand my questions at all, either by being intentionally dismissive or by not understanding, the owners seem to be from eastern Europe but based in Ireland.
Reputation I reviewed on Cryptocompare as well but it seem that the reviews there are mostly fake, If you look at the style of writing it is very similar to what is posted on the Facebook page and also multiple reviews have the same writing style. They have suggested that the bad feedback may be due to sites being setup similar to theirs to scam potential customers. From my opinion it seems like disgruntled customers who did not get a response in a reasonable time frame.
Conclusion: I would not recommend using MineShop if you can build the rig yourself, the biggest let down in my opinion is the lack of support (order wise and any questions about the hardware you have been sent). Customer service is key, especially when ordering online and when the order value is significant.
Bad experience with this guy , uses cheap parts and offers no warranty whatsoever , also mines the rigs for several weeks before putting up for sale as brand new . Ignorant and difficult to deal with . Stay away from mineshop.eu Will charge you for all postage costs and repair even if rig becomes faulty after a few weeks . you have been warned
They are selling FAKE delta fans , 5 fans failed just after one month of use . If you would have to RMA your product you will pay for return shipping cost. It's one man operation shop I would avoid .... ( and I'm experienced miner) have over 50 delta fans which are running for almost 2 years bought from different shop.

What guarantee do we have that you won't run off with the BTC ? You homo sapiens that holds hundreds of BTC, lets put one to play with this low IQ game like a chimpaze enjoying entropy momentum.
I think that the "homo sapiens" who hold hundreds of BTC wouldn't care about earning 4 more BTC, especially if they need first to send you one without any collateral

C'est un peu normal, il faut bien qu'ils vérifient qui réclament les fonds. A ce propos j'avais cru voir que certains rachetaient des comptes FTX à moindre coût à des gens qui ne voulaient pas attendre le résultat de longues procédures incertaines, dans ce cas vont-il pouvoir récupérer les fonds ?
Je ne vois pas comment ils pourraient faire, sans le KYC des comptes en question.. Peut-être que ceux qui ont acheté des comptes ont fait le pari que FTX allait rouvrir dans le futur comme si de rien n'était et espéraient pouvoir retirer les fonds à ce moment-là ? Je ne sais pas si tu parles de ça, mais j'avais en effet vu une entreprise qui faisait sa pub (j'ai essayé de retrouver la boite en question et j'ai trouvé Xclaim, mais je ne suis pas certain que ça soient eux qui faisaient leur promo sur reddit), et qui rachète les comptes FTX des gens qui ne veulent / peuvent pas tenter de récupérer leurs fonds. Est-ce possible qu'ils aient un accord en tant que boite de "recouvrement" avec FTX ? Ça semblerait douteux et illégal non ?

Hello i am New in bitcoin mining i want to ask if the GekkoScience Compac F is the best mini usb miner? I know GekkoScience have also better ones but not with only 15w i want try lottery mining with it. Do i need to run my pc with the USB miner together or can it run standalone? I mean it need Internet or is it with wifi? If it has wifi and it can run standalone can i usw a USB charger that supports 15w or do i need a USB hub? If it works not standalone what do you use to run it? Can i use raspberry pi3 or raspberry zero w? I ask because of energy costs.
And for better understanding the GekkoScience Compac F can mine 300 - 500GH a RTX 3090 only 120 MH? Means 0.12GH?
You will need a computer, the Compac F doesn't have WIFI. You need a computer with cgminer installed on it. It is difficult to say if the Compac F is the best usb miner, but yeah, it is an excellent one (a block was already found with one some months ago). You can have a look on Gekkoscience R909 too, if offers more hashrate. Gekkoscience products are stable and reliable, they are excellent. You can also check the DIY project named Bitaxe, it runs standalone, and they are actually starting to sell the first batch (you can build them yourself or buy them already assembled). But we actually don't know if they are as stable as Gekkoscience's products. For the USB hub related question, you should definitely use a strong USB hub with a Compac F, the USB port of a Raspberry Pi would probably don't offer enough power if you want to overclock your USB asic.

Salut à tous, Je me suis pris une bitbox02 pour compléter mon trezor 1 et ledger nano X. Assez sympa, le système tactile pour les mots de passe est un peu perturbant au début mais on s' y fait.. Je trouve le system de backup sur microSD à la fois génial et effrayant Pourquoi la microSD est effrayante ? Je suis de plus en plus tenté par une bitbox btc-only, mais c'est le prix + le tactile qui m'effraient un peu J'utilise Electrum, et un vieux Ledger Nano S (donc pas concerné par les mises à jour qui puent pour la seed), et je cherche à remplacer le Ledger pour une solution full open source. Je pense partir sur une Coldcard Mk4. ça me semble moins potentiellement capricieux que la bitbox et son tactile, mais j'hésite encore.

This is one of the best bitcoin sites I have seen in 2023, all the data provided is just awesome and the way that the information is displayed is a great design.
Since you are not running ads campaigns I would suggest to add a donations section in the footer, maybe that way you can get some income with the project. And I would like to know if there are plans to make the same with other altcoins. It would be nice to be able to see the same information for coins like LTC or ETH.
Yeah, I agree with you, I forgot to mention it in my previous message, but I'm also wondering if you accept donations to be able to contribute to the good continuation and costs related to your site? OP, if you are interested, I'd be happy to send you a few sats to help with site hosting costs etc...

Don't you think that a Facebook page and a simple email address are a bit flimsy for motivating people to send you their ASICs?
What's more, you're not even talking about the cost of hosting ASICs? Is it included in the price paid for electricity?
What about import taxes on ASICs in Russia? + Won't international sanctions make it difficult for European countries or countries like Canada and the USA to import ASICs?
You should offer more details, legal mentions, in short, something to make you look a little legit. Reading your post, I personally have strange vibes, it seems shady honestly. If you add to that the fact that you're a totally unknown newbie here, I think many members will be full of doubts about you, and will probably prefer to turn to reputable companies, even if they have to pay a bit more, at least they'll have the guarantee of not being ripped off.

Bravo OP! I find your site clear, efficient and extremely pleasant to browse, and I've bookmarked it. I really like the fact that all the useful information are concentrated in one place, and from my point of view there's nothing to complain about in terms of the quality of your site. It's even in dark mode, so everything is exactly as I want it. I don't really agree with the comment below, OP's site is much more pleasant and exhaustive than coinmarketcap's BTC page. And at least it will mean fewer cookies and browsing data for Binance (as CMC belongs to the Binance group), I'm glad to have such a website. This page ( https://timechaincalendar.com/en) is very cool too, well done!

You're right, but at the same time, there are places where electricity is close to free, and minimum incomes are low. People who earn more than the minimum income there can accumulate cheap, second-hand ASICs from a long-term perspective. There are also those who back in a days bought L3s (for example) at 70-80 usd, who mined on Nicehash or converted their LTC/DOGE into BTC and sold during the last bull run, must have been very pleased. Or with a 100 usd S9, actualy you earn 0.00090849BTC per month approximately, ROI would be 5-6 months with a dirty cheap electricity. It makes sense for someone which is almost not paying electricity, even with the rise of difficulty. So if the said guy accumulated cheap S9s or S15s for example, when difficulty was lower, it could be profitable for him. For example, I was recently in Kosovo, with someone who had very very cheap electricity. He collects the cheapest ASICs possible, and has been accumulating them for a long time (several years). This gives him an income that's not insignificant back home (minimum wage more or less 200 EUR in Kosovo if I'm not wrong). Of course, we're not talking about mining on an industrial scale, but what I was trying to say is that over the long term, some people manage to obtain a small amount of sats that is not insignificant in proportion to their country's minimum income. It's much the same in Russia, where there's industrial mining that requires a lot of resources and investment. But you also meet people who have a few dozen ASICs accumulated over the years that generate an income that would enable them to live a little more comfortably. Of course, this isn't possible overnight, but I sincerely believe that places where the cost of living is low, and electricity affordable, are one of the few interesting opportunities for 'pleb' mining, even if it doesn't even represent 1% of the total hashrate and is insignificant in the proportion of the total hashrate. I can give my personnal situation as an example. Where I live, incomes are low, but if you manage to earn 100 EUR a month, you can already say that your rent is paid in most of cities. That's appreciable, even for people who earn more than the minimum wage. Personaly, when I work, I earn like 6-7 times the minimum legal salary, so I could afford to buy more ASICs from time to time. My mining farm is not crazy big, but thanks to it, if I wanted, I could stop working now and just sell my BTC each month, and live in a very comfortable way as long as the difficulty stays in her actual range. It wouldn't be possible in a Westerner country or in a country where cost of living is high. So keeping all these accumulated sats aside for the long term makes a lot of sense in my situation. It's almost free DCA, insofar as my ASICs are already profitable. On the other hand, from a professional, stable and industrial mining point of view, I totally agree with you. But that doesn't mean those guys who make the equivalent of a minimum income in "BTC Savings" every month don't exist, and in their case, if they accumulate these sats and sell in bullrun, it can be a very profitable game for them. Even if it's on a small scale, the ratio of earnings to cost of living could be to their advantage
