... Hi, I need Bitcoin Public Key Database with balance Please upload Bitcoin Public Key Database with balance your site http://addresses.loyce.club/... I can share such database. It is 5 MB as .rar. Inside are: transaction ids, amounts, public keys. You can obtain such file by go program with name "bitcoin-utxo-dump". I was reading about bitcoin-utxo-dump and looks like the right tool for this project, the files are not 5 MB, the file should be around 7GB and it takes close to 20 minutes to get all the unspent coins. After that we should group the unspent transactions from the same address and that way we can know the balance from each address... The thing here is, you should run the dump each hour, then group the address and make a new csv file with the data, then update the database from the csv file, sounds as a busy cron job, but is possible.

Update:
The casino paid me the full amount no questions asked!!!
I can’t believe it!! The excitement is hitting in full effect!!
It's crazy this is a big win, I saw the replay just now. Wow, wanted paying that much with a $20 bet is just insane, my best multiplier in that slot so far is x660, but sadly it was with a min bet, so, a big multi but not a big profit. And is nice to know how bitcasino handles the situation, they are professionals. And I remember they have been there for a long time ago, if I'm not wrong I have an account there since 2016 or 17. I like that wanted slot because the max multiplier is x12,500 but there are some slots on ELK that pays x50,000 as max win. |

But I guess there were many unrecorded Bitcoin giveaways, gifts, donations, or whatever that's higher than that. If Laszlo could easily give away 10,000BTC in mid-2010 for just two pizzas, how much more in 2009? If Gavin in 2010 easily donated a total of almost 20,000BTC to be given away just for solving a captcha, how much more the donations in early 2009 when Bitcoin didn't even have a price yet? Even on this forum, there were users who donated as big as 50BTC. But that wasn't much back then.
If we are talking about bitcoin Airdrops, then the 19700 BET from Gavin is one of the biggest in bitcoin history. But we are talking about the old day when the bitcoin price was lower than $1. I would say the casinos have apport the biggest "BTC airdrops" in the past years, Just think about how many people have claimed the faucet on Freebitco, or how many people get prizes on the casino, or tips in the chats. I remember in 2014 how the casino called Luckybit used to have a nice Chat Lotto, where people post their address and the chat lotto sends BTC direct to the user's address, the normal prize was between 0.005 - 0.001 btc, and in the happy hours they pay crazy lottos up to 1btc. |

Hablo muy mal español, así que por favor perdona cualquier error. Estoy pensando en hacer una residencia en Nicaragua. Me pregunto cómo es la escena de la criptomoneda en  ? 1) ¿Los bancos locales te dan un momento difícil de transferir de los intercambios? 2) ¿Hay puntos o puntos? Hola SpanishBitcoin. Por lo que he leido no hay ATM's en Nicaragua, pero he encontrado un articulo bastante interesante sobre el tema, el cual nos muestra los diversos métodos de compra venta de Bitcoin en ese país: https://www.criptonoticias.com/tutoriales-guias/donde-comprar-vender-bitcoin-nicaragua-2021/El articulo tiene 2 años, pero seguro que encuentras información relevante. Aquí el tema es que cuando tu haces la venta de cryptos esto lo haces a tu banco en tu país de origen, así que no creo que tengas problemas. Y en caso de que se te complique, este tema, una solución es viajar a El salvador cada vez que quieras vender cryptos. Es algo tedioso pero realmente no está tan lejos. |

La realidad es que el problema no es la tecnología ni el tipo de wallet que elijas es el individuo quien falla y ahí no hay algoritmos, IA, etc. Y ni que chatgpt sea tu mejor amigo, consejero...
Es bien sabido colega que por mas seguro que sea el sistema, una vulnerabilidad que siempre estará presente es el factor humano, y es impresionante lo que se puede lograr con ingeniería social. Creo que la divulgación o estos "errores" si es que esto se puede llamar así, es más bien descuidó, confianza.
No se si considerarlo un error, ya que la persona fue victima de un ataque, el usuario desconocía el riesgo implicado en generar las direcciones en linea, así que mas que descuido aquí el factor fue la ignorancia. Y les dejo este dato, hay perros entrenados para encontrar memorias USB*, en lo que leí sobre eso, pensé y que tal si pueden diferenciar entre una HW, ese dato final si es medio en serio y medio broma, pero a ese punto "tecnologoperruno" estamos.
Esto es bastante interesante aun que los USB son el 99% inofensivos, mas bien deberían de entrenarlos para buscar rubber ducky o flipper zero, esos juguetes son bastante peligrosos. |

As i mentioned before, github all the way and you will find the right code, for example: Rummy Python: https://github.com/OrderAndCh4oS/Python-RummyRummy full-stack: https://github.com/sshh12/RummyThat's the easy way to build it from scratch, now you only need the users/depo/withraw engine. You can handle the coins with API providers or you can have your own nodes on a VPS and have better control over the coins. But this option isn't easy at all because Bitcoin node is heavy as hell and you need a robust VPS for it. |

Y aunque sea algo inevitable, aveces siento algo de frustración por la aparente inacción que puede mostrar el equipo de desarrolladores.
Si estamos hablando de un proyecto tan relevante como Bitcoin, la seguridad deberia ser la prioridad y aún así, pareciera que por ahora lo mejor para varios de ellos es mantener el proyecto lo más fiel a la version original, en pro de tener a la comunidad unida.
No sientas frustración colega, ya que los desarrolladores van a actuar en su debido momento, este es un proceso que va por partes, el primer paso es el desarrollo de erramientas para encriptado que resista ataques cuanticos, y este paso ya se ha dado, y es un paso enorme, ahora los desarrolladores de cryptos tedrán que encontrar la forma de integrar este encriptado a blockchain y sustituir el sha256. Pienso similar el tema es que si la amenaza es tan grande tambien es un, "Y que queres que haga?" esto es como cuando las murallas dejaron de ser utiles como defensas en las guerras, al aparecer la polvora en toda su magnitud, cuando el paradigma cambia ya no tiene mucho sentido seguir investigando mejores murallas tal cual las conocemos, y es mejor centrarse en nuevas tecnologias/defensas.
Me gusta tu analogía colega, pero por mas grueso y alto que sea el muro este es ineficiente contra ataques aereos, al ser un tipo diferente de ataque es necesario crear defenzas contra este. |

I am looking for a developer for a popular skill-game. the skill-game is an old and popular one but my idea how to play it and use it in tournaments is new and a nice moneymaker for whoever will offer it or add it to his casino. it should be buy-in tournaments.
Would be nice to know the name of the game, but if it's popular as you mention, then for sure you can find an open source code on github, that's a good starting point. The question is should it be a dapp, an app or on a website? I have no idea.
Buy-ins should be in crypto and stablecoins so everyone can participate.
For example, it would be perfect for casinos with many users/members like Stake.com or Freebitcoin.in etc.
If the idea is to bring it as a service for the casinos, then you need to make an API for the games provider, and you are not the one who handles the coins or the balance, your service should only make the tournament and inform to the casino who is the winner based on the games results. I think the hard part of the project isn't to develop the engine, the hard part is to convince stake and freebitco to integrate it in the casino. |

Lo que me parece extraño es el hecho de que aparentemente el servicio es gratuito cuando la competición cobra dinero.
¿Existe la posibilidad de que en las letras pequeñas de esos servicios gratuitos de alojamiento exista una clausula de recopilación de información para terceros?
El gancho es que si en cierto momento tu servidor se queda corto o necesitas mas recursos entonces tendrás que empezar a pagar por estos, pero si no los requieres el servicio quedará en el modo gratuito. Y otro factor a tener en cuenta es que cuando creamos la cuenta tenemos que hacer un pequeño pago con nuestra tarjeta bancaria, el dinero es reembolsado, pero en otras palabras sin cuenta de banco no podemos obtener este servicio, y el echo de que demos de alta una tarjeta no quiere decir que el servicio nos cobrará de forma automática, simplemente es para verificación de identidad. Pero concuerdo contigo Hispo, personalmente nunca creí ver este servicio gratuito. |

Hola.
Me pregunto qué pasará con estas carteras cuando la computación cuántica vulnere las claves Bitcoin tal y como las conocemos ahora.
Bueno, si estamos hablando de un ataque cuántico, en realidad no importa el servicio que ofrezca las llaves privadas o las genere, al final se trata de la misma moneda, mismo algoritmo y misma cadena de bloques. En teoría, si una computadora cuántica capaz de romper la seguridad de Bitcoin existiese hoy, estarían igual de vulnerables las wallets frías generadas en un ambiente air-gapped, cómo aquellas que son consideradas hot wallet y las llaves están en contacto con internet. Creo que no estamos dimensionando la magnitud del riesgo, ya que no es un ataque hacia las carteras, sino que hacia las direcciones en general, entonces las carteras pasarían a segundo plano, ya que como mencionamos anteriormente, en el momento que con un ataque cuántico el atacante pueda obtener la llave privada simplemente dando la dirección es un escenario demasiado roto. Tardará unos años para que esto pase pero es inevitable. |

Para los que no sepan que es un VPS (Virtual Private Server), es una computadora virtual que se ejecuta en un servidor, este servidor puede tener windows, linux, entre otros, y dependiendo de la configuración (Procesadores, RAM, Disco Duro) va cambiando el precio. Pero hay que dejarlo claro, este servicio no es tan barato si necesitamos buenos recursos. Y muchos se preguntarán, ¿para que quiero una computadora corriendo 24/7?. Algunos de los ejemplos son. 1.-Ejecutar nodos de criptomonedas. 2.-Hacer ataques de fuerza bruta. 3.-Minería. 4.-Como servidor web. ... Así que después de esa introducción puedo ir al punto, normalmente un VPS tiene una renta mensual elevada, pero hace poco descubrí un VPS el cual cuenta con planes gratuitos. Las especificaciones del servidor son bajas, pero aun así gratis de por vida es algo interesante. Y lo mejor es que el servicio no ofrece una empresa grande, estoy hablando de Oracle. https://cloud.oracle.com/https://docs.oracle.com/iaas/Content/FreeTier/freetier_topic-Always_Free_Resources.htmEl almacenamiento es de máximo 200 gigas, así que no podemos tener cadenas de bloques como las de bitcoin o etherum, pero si podemos usar otras cadenas de bloques mas pequeñas como dogecoin. Todo depende de que uso le quieras dar a tu computadora virtual. |

Let me explain the difference between martingale and my method:
Martingale: at the end of the run, your profit equals the initial bet. For example:
$2 on x2 - lose
$4 on x2 - lose
$8 on x2 - lose
$16 on x2 - win
Profit=$2
My method: At the end of the run you double up the total betting amount, let's say you bet a total of $50 in 100 bets and win in the last one, you get back $100.
That's why is an enormous difference between my method and martingale, they are totally different in the long run. And even if its a variance of Martingale, I feel this method deserve it's own name.

So JustDice has some expert settings? I get that you increase the bet with 000001 after every loss, but what about the multiplier? How did you set it up?
The site doesn't have a betting bot by itself, but they allow us to use javascript bots in the browser console, that's how I do it. Aren't bets in a casino using bots (any game process automation systems) prohibited? Are you not afraid that your account will be banned, lose your deposit and possibly be blacklisted with the inability to play in this (and possibly other) casino?
This casino allows bots and multi accounts, I have talk with them before running the bots and they agreed. So, we don't have to worry about this because we are not braking the rules. What's your biggest red streak thus far and highest multi you have hit? You've only tried this on just dice? I would be curious to know if different sites have different results, maybe try 1 of the other dice sites and update us.
If we wanted to try this ourselves we would have to code a bot or find 1 like suentjie correct? None of the sites that i know of have a way to set up their site bot like this.
So far my biggest losing streak was 100,000 bets, and my biggest multi was x9900, But I'm running with that limit, I should make the bet lower and run for a x990,000 just for testing. But that amount of bets takes hours. This method is already bad from start as you decrease your chances to win by each bet you place during that betting run.
I do not agree, that we decrease our chance to win because as I mentioned before, the odds to hit a x500 is close to 1/500 bets. So, the odds to hit are the same. |

On each bet, you are increasing the betting amount and at the same time, you are increasing your odds for which there is an increasing losing chance on the bet. And in this way, there is a low chance to e a winner as on each bet you are increasing the odds. As a result, the possible loss is higher than being the winner.
The odds is a nice topic to talk about, what are the odds to hit an x10? 1/10, what are the odds to hit an x100? 1/100... so, when you are chasing an x540 you have done x539 bets, so, feels like we are moving with the odds, in other words, while lowering the chance to win then more bets on the line. I'm not sure if you are trolling or not.
I'm sure I'm not trolling, I'm right now running 3 bots with this method on virtual machines. You don't have an infinite bankroll. Eventually, you will hit a losing streak so large that it bankrupts you.
What if you are using a coin with a low cost, like doge coin, and start with 1000 doges bankroll betting at 0.00000002, I know is not infinite bankroll, but the amount of bets you can do is more than 1 million. The casino sets its own betting limits based on its risk profiles. Nobody would take this bet because it could bankrupt a casino.
I agree with this, I'm not making a massive profit with it, but is a constant win. What game are you playing exactly because according to what you said if I’m to use this strategy of yours I’ll have to use a payout of 2x and that will reduce the odds of me winning to less than 50% which means if I’m to go on with this method I’ll experience more loses than wins.
I'm playing Dice right now, on a casino where the max multiplier is x990,000. is the same casino where I hit x300,000 in the past ( https://bitcointalk.org/index.php?topic=5406456.0) And with the current bot I already have some crazy multipliers. x8048 https://just-dice.com/roll/6110001180x9900 https://just-dice.com/roll/6109916608x6700 https://just-dice.com/roll/6109899409Look at the timestamp and you will see they are fresh. But I would like to focus the conversation in the betting method, now I'm rolling with 50 balance and starting bet is 0.000002 with 000001 increments. it looks something like this: |

The logic behind this betting method isn't complex at all. You bet $2 on x2 and on the next bet you sum +1 to the bet amount and it looks something like this: $2 - x2
$3 - x3
$4 - x4
$5 - x5
...
$10,000 - x10,000 I know, in the example looks like a lot of money to bet, but now think about starting from 0.00000002 BTC or better known as 2 satoshis, with increments of 1 satoshi, you can be betting in the long run with 0.001 btc. To do this I hire a guy to make a betting bot for a casino, and is looking good, is really hard to find a losing run with it. So, what do you think about this betting method, Has someone tried it in the past? |

if the game is Provably Fair, that means we can change the seed at any moment, and the past bets don't affect the future ones. The fact that the casinos have a house edge is the way they win in the long run and not by manipulating the outcome of the bet.
And the interesting fact about this is the fact that we can get a massive win back-to-back with the right luck. you can get 2 x999 on plinko in less than 10 bets, or two x1000 on dice in less than 5 bets.

Not many people were mining with high-tech mining machines when Bitcoin was released (2009, if I'm not mistaken).
Thus, bitcoin was vulnerable to a 51% attack by a big company or an individual with huge resources.
But was there any such attack on Bitcoin around that time?
Bitcoin has a lot of soft and hard forks, but it doesn't have 51% attacks yet, the closer we get to that was on January 2014. Potential threat averted In January of 2014, a mining pool called Gash.io got so big that it neared 51% of the total mining power. This, of course, created some panic in the Bitcoin community but was fixed shortly after by miners who left the pool in order to balance things out. Additionally, the pool committed to a 40% limit for its future operations. But there are some fresh examples of 51% attacks in the past years in other blockchains: Bitcoin Cash (May 2019) Two Bitcoin Cash mining pools, BTC.com and BTC.top, carried out a 51% attack on the Bitcoin Cash blockchain in order to stop an unknown miner from taking coins that he wasn’t supposed to have access to, while the network forked. Even though some would argue the 51% attack was done to help the network, it still demonstrates the power these two mining pools have over the network.
Ethereum Classic (January 2019) Coinbase identified a “deep chain reorganization” of the Ethereum Classic (ETC) blockchain which included a double spend on Saturday, Jan. 5 2019. Subsequently, Coinbase halted all ETC transactions. Another exchange, Gate.io, also confirmed that it had picked up at least seven double spend transactions after conducting its own investigation into the attack.
Vertcoin (December 2018) 4 different attacks on the Vertcoin network (a relatively anonymous coin ranking below #200 in the cryptocurrency charts) concluded in the theft of around $100,000.
Bitcoin Gold (May 2018) More than $18 million were stolen through double spending in a Bitcoin Gold 51% attack conducted by an unknown malicious actor. Exchanges tried to fight off the attack by waiting for a longer amount of confirmations before approving transactions, but that did not seem to help a lot. But you have a point there, we are talking about the old days, maybe satoshi did some test to verify the 51% attack, who knows. In the end the real risk for the 51% is the exchanges. just think about it, you send the cryptos to the exchange, sell them, then make the 51% attack and get back the coins. Sound easy but to get the 51% of the mining power isn't easy at all. |

Una vez recuperadas las llaves privadas ya estaba listo para formatear y configurar de nuevo el servidor... aun que fuera un proceso tedioso y tardado es lo que se tenía que hacer, así que descargué linux en un USB y inicié la computadora desde este. Una vez que ya estaba en la versión en vivo (ejecutando el sistema desde el USB) decidí probar por ultima vez rescatar el disco. Y al hacer fstab esta ves si funcionó corrigiendo los errores de dicho disco. Reinicié el servidor y el sistema funcionó bien. Así es que un final mas que feliz.
La cantidad de monedas era grande pero sin mucho valor, hablamos de 400 monedas de una cadena de bloques que tiene un total de 7 millones, pero al pasarlo a bitcoins es 0.0016BTC.

Hoy les traigo una historia algo épica, que parece chiste pero es anécdota. Hace 3 días compre criptos para jugar en mi casino, ese que tengo instalado en mi red local y cuenta con 4 juegos: Plinko, Dice, Slots y Otro. Es una práctica bizarra ya que no se puede ganar o perder cuando tu eres cliente y servidor al mismo tiempo, pero me gusta hacerlo por puro deporte. Sin embargo me percaté que algo estaba mal en mi servidor, ya que cuando intentaba modificar los archivos estos me decían que solo son archivos de lectura. Y he aquí en donde empieza lo divertido. Reinicié la computadora, y el sistema operativo se quedaba cargando, intenté con "ctrl+alt+i" para ver el log y encontré el siguiente mensaje: A start job is running for file system check on /dev/disk/by-uuid/... (10min 00s / no limit) Ahí entendí que algo estaba mal con el disco duro, y me dije a mi mismo, no hay problema, puendo entrar en en rescue mode y corregirlo con fstab, y fue lo que intenté, pero cuando ejecutaba "fstab /dev/sda" me aparecía el error que la unidad estaba en uso, así que procedí a desmontar la unidad "umount /dev/sda" y al intentar el comando fstab nuevamente, aparecía el mismo error. Por lo cual procedí con el comando "lsof | grep /dev/sda" y vi que el disco estaba ocupado con fstab corriendo de forma automática. terminé el proceso con "kill -9 1010", antes de proceder con fstab para reparar el disco decidí verificarlo con "smartctl -a /dev/sda" y me arrojó el siguiente error: Error 336 occurred at disk power-on lifetime Y ahí fue cuando entendí que mi disco duro pasó a mejor vida... Y muchos creerían que la solucion es tan fácil como adquirir un nuevo disco y instalar todo de nuevo, pero el problema es que tengo criptos en el nodo, y antes de formatear había que recuperar esas llaves privadas. Desde el modo de recuperación monté la unidad sdb en la cual tengo mi nodo, ingresé a la carpeta, i ejecuté el nodo sin conexión a internet: Listé las direcciones: Y en las que tenían balance apliqué el dump de llave privada: Y fue así como recuperé las monedas, ahora el disco puede morir en paz. Fue un proceso que duró días y me salté varios pasos en la historia, pero creo que es una buena historia de cryptos para compartir con la comunidad. |

When BTC reached $69000. I didn't choose to sell it. but the current price of Bitcoin dropped to less than $30000. Is it the most reasonable choice to sell BTC now and turn your attention to other investments? I hope to get some good suggestions. Although I have held BTC for many years. I am not good at management.
here the thing is how much do you spect from the investment, because to get a x4 with bitcoin would be really hard, at the current price we would need to see it going up to $120k, to get that x4. But with other coins isn't that hard, I mean, if we look at LTC all-time high we will see how it was up to $360, while now is at $90, so, to make a desition about what coin is better to invest first look at those coins ATH, and that will give you a good hint about your next investment. |
