In this report, only 3% of the world's population owns bitcoins. I'm not talking about companies and investment funds, of course. That's 240 million people as of 12/31/2024, some of them have only a few sats. For comparison, Satoshi would have 4.6% of BTC and about 7.5% would be lost (estimate), a low estimate of 12% (while other estimates are around 28%).  There is quite a bit to read in this document, I have attached the table of contents. |

Imagine if all prices were displayed in satoshis like Marty Bent imagined with his extension Opportunity cost . In that case it maybe nice to receive your salary in satoshis, or not. What do you think about it ? (In France, salaries are mandatory in euros, and pay slips are very complex. Tax and administrative rules are complicated, and few companies pay bonuses in satoshis, probably due to this complexity) |

Opportunity cost est une extension dispo sur les navigateurs Brave et Chrome pour le moment. Elle convertit les prix en btc et satoshis. Le but est de s'imaginer un monde dans lequel tout peut s'acheter en btc, mais également de se rendre compte à quel point certains achats sont inutiles. C'est marrant comme extension, mais est-ce que ça ne permet pas aux hackers de mieux cibler leurs victimes ?

I've long been aware of dogs that sniff out all sorts of things—drugs, cash, and more—but I didn't know that some dogs were specifically trained to sniff out digital devices. These dogs are called digital detection dog, electronic sniffing dog, tech detector dog, sniffer dog or in french e-dog. The number of these dogs is still very limited, and the use of such a dog is only considered in the context of a major criminal investigation. One can imagine that if one day states want to confiscate all citizens' hardware wallets, the dogs will have a hard time finding them in Western homes crammed with home automation and electronics of all kinds. (but the dogs found devices in the case of Todd Jordan for example, they seem to be very efficient in fact) Still, in France, we have between 2 and 5 digital detection dogs (including the famous Snatch), in the USA there are about 100 dogs, in Australia between 10 and 20, and in England between 5 and 10 dogs. You can find various videos about how the dogs are educated and how they can find digital devices. https://www.youtube.com/watch?v=GQOfza0iMH8 |

Financial infidelity refers to the act of withholding important financial information, such as debts, expenses, income, or assets, from one's partner in an attempt to deceive or control the couple's financial situation. This can include secret bank accounts, hidden investments or holdings of cryptocurrencies. This phenomenon can have serious consequences particularly during divorce. If hidden accounts are discovered, this can, depending on the country, have various legal consequences such as a tax audit but also prosecution for fraud, etc... https://www.cnbc.com/2023/05/20/bitcoin-in-divorce-how-spouses-hide-assets-crypto-hunters-find-them.htmlHimonidis, who is also a licensed private investigator and a computer forensic expert, estimates that 25% of his divorce-related cases involve some elements of cryptocurrency. Some of those cases, he said, are simple and straightforward — situations where, for example, a cryptocurrency such as bitcoin is a custodial asset held in a brokerage account or on a trading platform In the case, DiMichael said, the husband had a Ledger and then the wife found the device in the house and took it. “So the wife had the Ledger, but she didn’t know the pin number, or password. And the husband — he knew the pin number, but he didn’t have the Ledger.”
Neither could access the funds without the cooperation of the other. In one case, Himonidis said, he had to track around $2.3 million that was emptied out of a Coinbase account within a few months of divorce proceedings commencing. The crypto coins hadn’t been cashed out to fiat but instead moved as crypto to addresses outside Coinbase in a series of approximately 14 outbound transfers. New York is an equitable distribution state, meaning that a spouse gets 50% of the marital assets accumulated during the marriage. I think that in France, there aren't many cases in which one spouse seeks out the other's coins, and therefore no real specialist, like the one in this CNBC article. In France, there are different types of marriage contracts, and in some cases, it's not mandatory to split the assets acquired during the marriage (depending on the contract). How does this work in your country, and what would you do with your coins in the event of a divorce? |

Source : https://www.coingecko.com/research/publications/government-bitcoin-holdingsLes gouvernements détiennent désormais 2,3 % de tous les bitcoins  En avril 2025, les gouvernements détenaient collectivement plus de 463 741 BTC, soit environ 2,3 % de l'offre totale de Bitcoin. Ce chiffre marque une baisse par rapport aux 529 591 BTC enregistrés en juillet 2024. Certains pays, comme le Salvador et le Bhoutan, ont activement accru leurs avoirs, tandis que d'autres, comme les États-Unis et l'Allemagne, ont liquidé leurs réserves. On peut voir sur les graphiques de Coingecko les plus grands détenteurs de BTC. Comment les gouvernements obtiennent-ils des Bitcoins ?- Les États-Unis, la Chine et le Royaume-Uni ont obtenu des bitcoins grâce à des mesures policières contre la cybercriminalité et la fraude. Les États-Unis détiennent 198 012 BTC, provenant principalement des piratages de Silk Road et de Bitfinex. Les 190 000 BTC détenus par la Chine proviennent du système de Ponzi PlusToken, tandis que le Royaume-Uni a saisi 61 000 BTC suite à des affaires de blanchiment d'argent. - Le Salvador est le seul pays à acheter activement des bitcoins, acquérant 1 BTC par jour depuis novembre 2022. Le pays détient actuellement 6 135 BTC dans le cadre de sa stratégie financière nationale, considérant le bitcoin comme un actif de réserve à long terme. - Le Bhoutan utilise des opérations de minage hydroélectriques pour accumuler des bitcoins. Le minage offre une méthode unique d'accumulation de bitcoins pilotée par le gouvernement, sans achat direct sur le marché. - L'Ukraine a reçu plus de 256 BTC de dons de donateurs internationaux pour financer ses efforts militaires et humanitaires. La plupart de ces fonds sont rapidement liquidés pour couvrir des dépenses urgentes, et seul un faible solde reste dans les portefeuilles gouvernementaux. Pourquoi les gouvernements vendent-ils des Bitcoins ?Tous les gouvernements ne choisissent pas de détenir des Bitcoins à long terme ; certains choisissent de liquider leurs avoirs pour diverses raisons. Contraintes budgétairesLes pays confrontés à des difficultés financières, comme l'Allemagne, ont vendu des Bitcoins pour combler leurs déficits budgétaires. Mi-2024, l'Allemagne a liquidé 46 359 BTC, contribuant ainsi à la baisse du marché. Market TimingLes gouvernements peuvent vendre stratégiquement des Bitcoins lorsque les prix sont élevés afin de maximiser les rendements. Ces ventes peuvent générer des revenus importants, mais elles risquent également d'affecter la stabilité du marché. Obligations légalesLes Bitcoins saisis font souvent l'objet d'une liquidation obligatoire. Les États-Unis, par exemple, vendent régulièrement aux enchères les Bitcoins confisqués, car la législation nationale exige la conversion des actifs saisis en monnaie fiduciaire. L'étude de Coingecko a examiné les données sur les principaux portefeuilles gouvernementaux en bitcoins au 24 avril 2025, provenant d'ArkhamIntelligence.com, Bitcointreasuries.net et Blockchair.com. Les cinq principaux gouvernements détenant des bitcoins sont les États-Unis, la Chine, le Royaume-Uni, l'Allemagne, le Salvador et le Bhoutan. Les avoirs en dollars américains (USD) ont été calculés sur la base du cours du bitcoin, qui s'élevait à 92 543,76 $.Prix du BTC ce jour, 24 mai 2025 : $108,413 |

Lien vers l'émission (dispo jusqu'au 23 février 2026) https://www.france.tv/france-2/envoye-special/7155515-emission-du-jeudi-22-mai-2025.html#about-sectionFaut-il avoir peur des cryptomonnaies ?
Ce sont des chiffres qui font tourner la tête. En décembre dernier, la valeur du bitcoin a atteint un record : 100 000 euros, +120% en un an. Pour Ethereum, la deuxième crypto-monnaie la plus vendue au monde, c’était +70% en 2024. Le cours de ces monnaies virtuelles ont été boostées par l’élection de Donald Trump qui s’est proclamé “président pro crypto”. La « crypto-mania » gagne aussi la France, près d’une personne sur dix en a acheté l’an dernier. Ces actifs numériques, très volatils, qui peuvent perdre et gagner de la valeur en quelques minutes attirent aussi bien les jeunes investisseurs que les épargnants en quête d’alternatives aux placements traditionnels. Les villes de Cannes ou de Talence en Gironde incitent même leurs commerçants à accepter ce nouveau mode de paiement. Certains y voient une révolution financière, d’autres une bulle prête à éclater. Comment fonctionnent ces nouvelles technologies ? Envoyé spécial a rencontré les Français qui se sont lancés sur ce marché numérique qui façonne des fortunes, de l’Islande à Metz. Face aux promesses de gains rapides, certains ont tout perdu. Comment repérer les arnaques dont le nombre explose ces derniers mois ?
Un reportage signé Laura Orosemane, Juliette Jonas, Justine Weyl et Anne-Laure Marcault Encore la peur, encore un monde "énigmatique", encore une bulle, encore le casino (comme l'avait dit Melenchon). Avec toutes les ressources que l'on a désormais, c'est fou d'en être encore là. Bon c'est juste l'intro. Donc dès la 10e minute, on "apprend" que le minage est énergivore + que la consommation annuelle de la Belgique (...) - En France, coût d'un btc = 120 000 euros d'électricité - En Islande : presque 4 fois moins cher. ----------------------------------------------------------------------- - Interview d'un particulier investisseur : petite pub vite fait au passage pour Stackingsat ? - Explication de l'inflation par cette personne : la critique de la monnaie officielle, "il est allé la chercher sur les réseaux sociaux" ... (encore un complotiste écervelé sans doute) ----------------------------------------------------------------------- Interview de Hasheur et présentation de sa boîte. 120 000 clients. ----------------------------------------------------------------------- Les memecoins : Crypto sans objectif. => Des images que l'on s'échange sur internet. ----------------------------------------------------------------------- Enlèvement, rançons et arnaques. Exemple d'un chef d'entreprise de 67 ans. Il passe par crypto.com, achète des cryptos et les envoie à un escroc. Il perd 180 000 euros (sur le scam Milleniumchain)). D'autres arnaqueurs l'appellent et lui font croire qu'il peut récupérer son argent en payant des frais (il perd alors 100 000 euros). Est-ce qu'il a perdu 280 000 au total, ce n'est pas clair, mais ça fait un paquet de toutes façons. Alain porte plainte contre sa banque et aussi contre X (pas twitter !). - Marc Bouzy, expert en cybersécurité, explique comment tracer les crypto sur la blockchain, comment checker un site (mentions légales), rien de vraiment nouveau ... Le final : la journaliste a perdu quelques euros après son investissement de 30 euros. Voilà c'est tout. Vous n'avez plus besoin de le regarder. bisous |

We talk a lot about El Salvador and Bitcoin, but do you know the Kingdom of Bhutan, this amazing country that remained quite closed for a long time (allowing television and internet only in 1999) and then quietly mined bitcoin in its own corner thanks to hydroelectric power?    The Kingdom of Bhutan is a small, landlocked country in the Himalayas, South Asia, bordered by China to the north and India to the south, east, and west. Bhutan covers approximately 38,394 km², its population is approximately 780,000 citizens (2023), mainly ethnic Bhoutanese of Tibeto-Mongol origin (Dzongkha and Sharchops) and Lhotshampas (of Nepali descent). - Dzongkha is the official language. - Vajrayana Buddhism is the state religion (about 75% of the population). - It's a constitutional monarchy since 2008, led by King Jigme Khesar Namgyel Wangchuck, transitioning from absolute monarchy to parliamentary democracy. - Relies on hydropower (exported to India), agriculture (rice, maize, fruits), and sustainable tourism. Tourism is regulated with a daily fee to preserve culture and the environment. - Capital: Thimphu. - Currency: Ngultrum (BTN), pegged to the Indian rupee. Thanks to hydroelectric power generation, the Kingdom of Bhutan owns more Bitcoins than El Salvador and manages its bag by selling when BTC pumps to also offset tourism losses after COVID. Bhutan holds about 16 times more BTC per capita/resident than El Salvador, primarily through its hydroelectric-powered mining operations, while El Salvador acquired its BTC through purchases and seizures (El Salvador has 6174 btc) (With a BTC at $103,000 for the example) Bhutan has 0.01527 BTC per capita ($1,573), while El Salvador has only 0.00096 BTC per capita (98.88 USD)Bhutan has been accumulating its BTC through mining since 2019, when Bitcoin was valued at around $5,000.In May 2025, Bhutan holds approximately 12,062 BTC, valued at around $1.25 billion, representing over 35% of its 2023 GDP ($3.02 billion). This makes Bhutan the fifth-largest government holder of Bitcoin globally, behind the US, China, the UK, and Ukraine. Bhutan holds smaller amounts of other cryptocurrencies, including 656 ETH (worth $1.74 million) and minor holdings in BNB, Polygon, and others.

It’s unclear when mining began, where it’s located and whether the scheme has turned a profit. (As for the start date, bitcoin was valued at $5,000 in April 2019.) It’s also unclear why Bhutan never disclosed the project to its citizens or international partners. |

Following the messages related to a topic about BTC purchases, I noticed that many users were hodlers and had never bought anything in BTC, but perhaps early adopters regret their past purchases? In the case of Laszlo Hanyecz (purchase of two pizzas for 10,000 btc in 2010), he said he had no regrets because it helped raise awareness of Bitcoin and promote its use as a currency.
What about you? Do you regret past purchases?

The issue of physical safety for BTC or cryptocurrency hodlers has been debated many times on the forum, and following several kidnappings of crypto influencers' relatives in France (but these kidnappings obviously also occur in other countries), how can btc influencers ensure their safety and that of their loved ones?
How can they both have visibility AND ensure their safety?

There are so many different rules in different countries, sometimes even BTC is banned, yet there are still BTC transactions in these countries. How does it work? Is it easy to sell btc in your country, or to buy something with it? What have you bought, for example? Or what are you planning to buy?

I remember this thread in 2017 in the French part. https://bitcointalk.org/index.php?topic=2425439.0At the time OP wanted to borrow to buy BTC. As we know today, he would have made a great deal (plus, a rare thing at the time, his banker was OK to lend him the money). Yet almost everyone advised him against it. Why was that? It seems to me that all investments involve risk. What makes borrowing to invest in BTC any more risky than investing in a start-up, opening a business or buying a house (which may be full of defects, for example)? If the person's financial situation is stable and the banker, after studying the file in depth, is OK, I don't see why you can't borrow money to buy BTC. In fact, this is what some large companies do. |

Good evening,
It's very possible that Cryptotag will hold another contest. The team is posting the contest on its social media (X, etc.) with links, and when followers arrive on Bitcointalk, they don't necessarily have an account. They can't participate because, obviously, they have no merit. However, requiring participants to have some seniority on the forum and merit is quite normal. What can we consider to possibly give these followers the opportunity to participate anyway? Is it even possible? What do you think? Thank you for your answers.

Les expériences des uns doivent absolument être partagées pour éviter les erreurs, les scams etc ... Du côté anglophone, un utilisateur averti a perdu plusieurs milliers de dollars en voulant faire un swap sur Truswallet : https://bitcointalk.org/index.php?topic=5536900.0Ici il s'agit d'un faux BUSD qui s'est affiché dans son wallet  Pourquoi ? Parce que Trust Wallet n’a pas de système d’authentification automatique ou de vérification de tokens. Toute adresse de contrat BEP-20 ou ERC-20 peut être manuellement ajoutée ou automatiquement affichée si elle suit les standards.. Ce qui signifie qu'il faut vérifier les contrats AVANT de valider le swap. Source : https://community.trustwallet.com/t/how-to-add-a-custom-token/213Source : https://community.trustwallet.com/t/beware-of-fake-token-scams/323075It is the user’s responsibility to know the tokens they are investing in. The Trust Wallet app cannot really tell if a project is legit unless it has been manually added to our asset database after a careful review. Imitation Tokens
The process of listing a token on a Decentralized Exchange (DEX) like Uniswap or PancakeSwap is open to everyone. Scammers will generate a token that tries to imitate old and new legitimate tokens. Before a legit token is listed on a DEX, scammers are already able to list their own. They will use the same name and logo which can easily attract an uninformed user.

In some countries, you can buy or rent a house in bitcoins. But what are the tax and administrative implications?
In France, you can, in theory, buy with BTC, but you have to pay taxes and notary fees in euros.
Since you also have to pay capital gains tax and (unless I'm mistaken) prove the origin of the bitcoins. Justifying the origin of funds when you won cryptos with games or airdrops and then sold them to buy btc 15 years ago is almost certainly impossible.
In the end, it doesn't seem so attractive to buy in btc in France because of the administrative and tax complications, in addition to the 30% capital gains tax (unless I'm mistaken).
How is it in your country ?
