Hello BayAreaCoins.

Is nice to see you reopened this service, it reminds me of the old shapeshift, but i think you have a typo or an error, let me explain it with an image:


The 10BTC fees are a little high for a 0.5btc buy, i think that fees should be in clams...

Congrats again, and thanks for making the clam stay alive.

@janggernaut yea many users have hit x9999 in the past few days and it all comes down to your luck, and your persistence only then can you hit it. Further the number of bets totally depends on users luck eg Kolloh did it in 3.5k bets, but seoincorporation did it in 33k bets, so unless you don’t try you won’t know how many bets it actually took you to hit x9999 and good luck in advance if you’re going to try hitting it.

Many users hit x9999 already? In the past few days? Who are those many players as I can see that seincorporation is the only one who posted that he hit that x9999 so far?
As I understand from the post you quoted above, kolloh and oldhiall hit the x999 (red line) and seincorporation hit the x9999 (grey line) but why do you compare the number of bets of them as they hit different payout which means different probability?

Hello panjul07, the x999 and the x9999 has the same probability... 0.00304%, that's the odds on that spot.

I hit the x9999 and 3 days after a user called kobe824 get the same multiplier but he did it with 3893 satoshis bet, getting back a profit of 0.3892 btc.

You can see those nice multipliers in the hall of fame:

The question here is why did you choose that exchange? How do you found it? Maybe you went to google and search the worst 10 Exchange and there it was. If you want to have a good customer service from an exchange, always go with the big ones. And if you don't want to use an exchange with KYC then just install atomic wallet, easy as that.

Hey guys, i want to know about your personal experience in winning prizes in casinos chats.

It would be nice to have a list of the sites to offer this kind of prizes.

I start this topic because yesterday i win more than 0.01 btc in lottos in luckyb.it, it was about luck because one of those lottos was a lil more than 0.009 btc while the normal ones are 0.0001 btc.


So, i hope to read some good chat lotto histories in this thread.

Con el paso de las horas, el problema base se ha ido simplificando mucho a golpe de resoluciones parciales. No obstante, me pregunto cómo lo abordarías en el escenario inicial de las 18! combinaciones.

Es decir, fuera del plano teórico (que lo tengo claro), en la práctica cómo habríais abordado la cuestión (desarrollo propio, herramientas tipo Brainflayer o similares, etc.), y qué expectativas de máquina se precisaría para dar con algo en algún momento de nuestra vida.

Es posible que el volumen de las 18! combinaciones no sea algo que sea factible abordar en la práctica con expectativas realistas, por lo que quedaría la cuestión de qué volumen es abordable, y en qué condiciones (de máquina, etc.). Las respuestas pueden quedar desiertas …



Buen día Ddmr... tengo que aceptar que al principio era imposible sin una computadora realmente potente. Y fue mi error, por que cuando quise calcular las posible combinaciones tuve un error de dedo y escribí 8! en vez de 18!, y al ver que 8! es 40,320 lo tomé como factible. Fue por esto que liberé muchas palabras del acertijo para que todos puedan con el.

Para resolverlo personalmente hubiera hecho los siguientes pasos:

1.- Usar crunch para generar todas las combinaciones posibles.
2.- Tomamos la lista de posibles combinaciones para después procesarla con un script en python de brain wallet.

Fuentes

Y ya con eso Smiley

Creo que si el premio fuera de 1btc, encontraría la forma de abordar el problema, tal vez con una granja de tarjetas de video. Wink

1Fucks... jajaja que buena addy te encontraste en el camino.

Muchas felicidades por ser el ganador, se ve que te divertiste resolviendo el acertijo y de eso se trataba.

La buena noticia es que estás en la seccion de español y dudo que alguien vaya a tomar tu premio con un Double spend, la mala es que no sabemos cuando se confirmará tu transaccion, te sugiero hacer un gasto doble con mas fees para que se confirmen pronto tus monedas Smiley

Dice bet browser does not work. No information about how to verify dice rolls. Maybe check your work before rushing to roll out new products?

Hello Yoloer808. Luckybit had a bug in the frontend of the dice bets verifier. And is normal for the first day out of the product, devs still working in fix the small bug.

The information about how to verify the dice rolls is in the next link: https://luckyb.it/blog/how-prove-dice-bet-was-fair/

Check the work? the Bets engine is working fine... The UI is working fine, the devs only had that small bug in the bets tabs but don't represents a big problem, it should be fixed in a couple of days and after that users will be able to verify the past days bets if they want.

Hope you like the new Game and i hope you had fun with it  Cheesy
3489  Local / Español (Spanish) / Re: Giveaway de fuerza bruta (0.001 BTC) on: April 22, 2020, 06:15:59 PM
<...>
Tienes razón. Si se usase como entrada al proceso de hackeo un fichero con las 18! combinaciones (ahora 8!), hay frase repetidas por la presencia de 4 términos "de", lo cual reduce la combinatoria al tratarse de permutaciones con repetición (en lugar de sin).

PR (permutaciones con repetición)= n! / (n1!*n2!* … *nm!)
Donde:
-     n es el número de términos (18).
-    n1 .. nm representa el número de repeticiones de cada término.

Quedaría pues:

18! / 4! (el resto de los multiplicandos del denominador se repite 1 sola vez cada uno, y multiplican por uno el denominador-> 1!=1) = 2,66766E+14 (266.766.000.000.000).

Es un ahorro importante en combinaciones teóricas.

En la práctica, para resolver el caso usando fuerza bruta, tengo dudas de si ciertos algoritmos serían capaces de llevar la reducción a la práctica. Por ejemplo, si para insertar un registro resultante de una combinación, sobre una tabla temporal, has de validar si ya está previamente creado, el proceso se ralentiza enormemente (y no digamos select distinct de la tabla resultante para crear la tabla final más reducida).

Quizás los procesos que trabajan sobre memoria pura y dura (sin usar disco) puedan manejarlo de manera que la reducción de la combinatoria (con comprobaciones sobre lo ya generado) sea más eficiente que generar y probar todas las combinaciones. Dependerá mucho del hardware usado supongo.

Teniendo esto presente, las 8! combinaciones pendientes se convierten realmente en 8!/3!= 6.720 combinaciones pendientes distintas ...


Gracias por el curso de números factoriales  Grin tenia un poco oxidado ese tema pero me da gusto recordarlo. 6720 combinaciones se puedes verificar incluso a mano con la merecida paciencia... Incluso se puede hacer una lista de las 40,000 en un archivo y con un comando filtra las repetidas:

Code:
cat lista.txt | sort -u > newList.txt

I feel like we are under a security race... The hackers are getting new methods for scam and sophisticated ways of social engineering, and new schemas and sites borns every day. So, with smart people behind the scams and dumb people on the internet trying to get free money that's the perfect environment t have tons of peoples getting scammed easily.

But don't worry, once they get scammed they learn the lesson. No one says Bitcoin lessons would be cheap.

Entiendo que hay 18! combinaciones potenciales para dar con la passphrase; es decir

640.237.3705.728.000 (o 6.402373705728E+15), y luego hay que probarlas … a ver quién lo saca …

Buena observacion colega, solo por eso les dare las primeras 10 palabras en el orden correcto para que ustedes adivinene las ultimas 8... un 8! se me hace justo, asi serian 40000 posibilidades aprox:

The chance to see bitcoin negative is the same chance than see the gold negative. Are things that never will happen... But why it happens with the oil? It was because people invest money in it, and when the oil company told them 'Where should i send the oil?' people start selling it like crazy. And some people were ready to pay for other ones to take those oil barrels.

That is what it seems like. But, as per suggestions given in their Telegram group, we have to focus on the Whitepaper. I suppose, Vitalik wont help us in this hunt. Cheesy

C'mon guys, that's not Vitalik sitting on the horse, horses don't have a horn... That's a Unicorn!

We can say is Vitalik sitting on the Unicorn holding a Unicorn... And the unicorn is Mining ETH on each step.

My 14 year old son bought Bitcoin with an itunes card and told me he has been claiming from faucets and earning Bitcoin. I feel like he's Satoshi's reincarnation lol he was born on april 6th and Satoshi on the 5th. He is mining Bitcoin, coding websites, and really interested in programming. Let me know what I should do...

You should give him the right tools to work with, if he really enjoys to code then you could gift him a vertical monitor. He will really appreciate it and becomer more efficient.

So to answer your questions:

Can the users change the private keys at any time they want?
With a hardware wallet, you can either "change" your private key by generating a new receiving address in the same wallet, by using a different passphrase to access a new set of wallets with the same seed phrase, or by resetting the device and generating a whole new seed altogether.

Can users load a secret key generated in vanitygen?
Not as far as I am aware. Certainly the major hardware wallets (Ledger, Trezor) only let you generate or restore from a seed phrase. You cannot import individual private keys or addresses.

Thanks for the information o_e_l_e_o, it would be nice if they implement a brain wallet feature with the option of save the address. But maybe that could be a new project.

As you say, bot are different things, so i should try to get one of those hardware wallets this year just to learn more about Bitcoin.

I would like the supply of bitcoin to be higher then the finite 21million. I believe, this BS is very limited for the whole world and will be highly scarce.
I want it to remain as it is.

21 million is already a lot and if it would be higher then the value that it will have today is going to be lower. That doesn't matter if it's only 21 million because we can have it even in the smallest portion.

And that's making bitcoin more reliable and in-demand.

The supply is already higher than 21 million, have you ever asked your selves why they are 8 zeros after the point? That's why people need to see bitcoins from its basic unit called 'Satoshis', so, we don't have to worry about the amount of bitcoin.

LO QUE REALMENTE HA OCURRIDO CON EL PETROLEO

Lo que está pasando con los futuros de mayo en EEUU es que especuladores que en realidad no esperaban quedarse el petroleo, sino solo comprar el derecho y darle "el pase", pero no esperaban en realidad quedarse con la producción real, se han quedado pillados con la compra. En un día y medio se cierra el precio de mayo y recibirán una llamada para preguntar "Donde te dejo el petróleo que has comprado", pero no hay demanda ni sitio donde guardarlo, así que están desesperados por deshacerse de sus "derechos" del petroleo de mayo, y no encuentran comprador porque no hay demanda en las refinerías y no hay depósitos donde guardarlo porque todo está lleno.
Ha sido una jugada especuladora, apostando que la economía se iba a reactivar antes, y con su apuesta han mandado un mensaje equivocado a las petroleras que han seguido extrayendo a un ritmo que no se puede aguantar, y ahora efectivamente parar los pozos y reiniciarlos en junio no es algo barato.

Muchas gracias por la explicación colega, ahora todo tiene sentido. Si creíamos que la gasolina estaba barata ahora va a estar regalada, todos con tanques llenos sin poder movernos. Dios castiga pero no a palos! Así que veamos que nos depara este alocado 2020.

Segura mente muchas ballenas predijeron esta caída y por eso fue catastrófico para el mercado.

This is a friendly reminder for every one in here that is planning to buy cold storage Ledger nano X, Ledger S, Trezor hardware and others. If you guys are going to buy hardware like these, make sure you buy it from the direct supplier or manufacturer. There are already some cases of stolen funds from the cold storage, and what does it mean?

It means that the cold storage is already opened, seed phrases are set up and save by someone who owned it first and would just apply as a seller to online markets like Amazon or Ebay. Then us, who wants to save little bit we tend to buy the items at the lower price than what it should be, the boxes are pretty easy to reseal again that it would look brand new as if nothing was tamper.

Or, if you guys already ordered one of these make sure that you factory reset it first before using. I wish this reminder of mine can help  Wink

Thanks for the warning Sanugarid, i have read a lot about this kind of hardware wallets, but i like more the old school way, vanity gen and paper wallet. But i write because i have a couple of cuestions about this Cold Storages...

Can the users change the private keys at any time they want?
Can users load a secret key generated in vanitygen?
