Yo @nomachine, what's that error dev/urandom thingy?

There is no problem with urandom it is enough random for all cryptographic purposes.

Please all read the next article: https://www.2uo.de/myths-about-urandom/

@nomachine one of the Hardware device that it is include most modern Intel processors, that is used to feed the entropy of the CSRNG of the linux kernel and windows core, use Thermodinamic properties to generate True random data:

From: https://www.intel.com/content/www/us/en/developer/articles/guide/intel-digital-random-number-generator-drng-software-implementation-guide.html
Quote
The ES runs asynchronously on a self-timed circuit and uses thermal noise within the silicon to output a random stream of bits at the rate of 3 GHz. The ES needs no dedicated external power supply to run, instead using the same power supply as other core logic. The ES is designed to function properly over a wide range of operating conditions, exceeding the normal operating range of the processor.

So that means that most of the modern PC are cable to generate True Random data.

Yes, but still when an average user will send any amount of bitcoin to someone, electrum by default will create two outputs, one to send the amount that you send to the other address and the other output to send the entire balance of the wallet to the change address. So this will automatically combine all of your UTXOs to the change address.

Reading this i thing that sparrow wallet have better coin control, you can avoid this easily in that wallet.

Not everyone know about coin control feature and not everyone is techy (or even willing to) to do all these complications.

They should know that, Well at least users who take care about their privacy.
323  Bitcoin / Wallet software / Re: Consolidating UTXO s in wallets. on: October 11, 2023, 11:52:19 PM
How is that even possible?

What you just explained is correct, if someone did exactly what you said there is no problem.

I suppose that @Kruw said if you merge some mixed or coin-join transaction with another transaction that hasn't been mixed before.

Let's say that you don't have enough experience with all this topic, but you want to enter in this (i am talking of a newbie user).

Example: you have some mix of sources in your UTXOs, some of them from mixing/coin-join and some other from a KYC source like some CEX.
In that case if the user mixes some of those KYC UTXOs with some coin-joined UTXO then all the previous work becomes useless.

I remember reading somewhere before that all the "chain analysis" that some companies do is not based on any reliable document or research. It is basically something like "I believe that those Utxos belong to the same person/entity" obviously there are some cases where there is no doubt, but there are also cases where there may be doubts

I don't have an in depth knowledge on how the open source software works, which has perhaps led me to more curiosity hence my question, yet I feel like Bitcoin still undergo some security guard and monitoring to safeguard it against the black-hats.

Open source software is transparent, any one can check the changes in the code before to put in to production.

If those changes affect the correct behaivor of the current network, nobody is going to run it.
325  Bitcoin / Wallet software / Re: Consolidating UTXOs in wallets. on: October 11, 2023, 08:12:00 PM
It depends on your coin control.  If you merge your faked outputs in the future, then it doesn't help.

I totally agree, people need to know what they are doing, if they start to merge utxos without any coin control, then all the previous mixers and coin-join transaction become useless and a waste of fees.
326  Bitcoin / Wallet software / Re: Consolidating UTXOs in wallets. on: October 11, 2023, 06:36:34 PM
You'd be better off consolidating them in a real coinjoin using Wasabi Wallet, BTCPay Server, or Trezor instead.

About better or not that is suggestive no? The point of a fake coinjoin is that it looks like a real coinjoin and only the people who participate on it can spot it as a fake coinjoin, all outside just can see a real coinjoin transaction.

Or can you spot the difference between them and tell us what is a fake coinjoin and what is a real one?

327  Bitcoin / Wallet software / Re: Consolidating UTXOs in wallets. on: October 11, 2023, 01:34:50 PM
Hi, I've using the wallet for some 3-4 months and it is really easy to use.
With excelent features like:

- RBF
- Integrated mixer
- Fake conjoin
- UTXO control

Along others, the only thing that the wallet is missing is the hability to import individual key, it only offer the option to sweep them.

Lo del 1$ dolar es por parte de binance al retirar USDT a tu cartera externa.

Y el usuario tiene buena reputacion, ademas el acordo primero mandar el bitcoin y una vez confirmada la transaccion on chain yo mandare el USDT.

Asi que lo considero un ganar ganar, ya que por lo que veo el esta en una campaña de firmas al igual muchos de los usuarios regulares del foro. Y segun entendi el tambien pierde un % en comisiones cuando el cambia su bitcoin a USDT en una plataforma P2P. Entonces al ser ya un trato directo tanto el como yo ahorraremos en comisiones Cheesy

335  Economy / Trading Discussion / Re: Binance Founder CZ said that, Copy trading now live on Binance. on: October 10, 2023, 06:33:51 PM
I don't know much about copy trading, but the latest news that I hear about it is people losing their money because they follow some pseudo-influencer. Obviously this was driven by an unskilled person. and by people who wants to be rich over-night.

Unless you know who are you following and what is he doing i don't recomen copy trading.

hubo muchísimas noticias que podrian haber modificado muchisimo el valor del BTC pero todas tuvieron un impacto de moderado para abajo.

Asi es totalmente de acuerdo contigo, muchas noticias que deberian de tener un impacto macro-economico y nada.

- tenemos por un lado a la FED Creando dinero a mas no poder.
- el surgimiento del BRICS
- la SEC solo retrazando los ETF de bitcoin.
- Continua la Guerra de Rusia y Ucrania
- Guerra entre Israel y Palestina
- Guerra comercial entre China y Estados Unidos.

Creo que parte de falta de crecimiento se debe a un pesimismo generalizado en relacion a la econimia global. Lo cual puede ser algo contradicorio ya que cuando los invesionistas sienten que sus acciones puede caer estos se refugiaran en Elementos que almacenen su valor, pero dado la naturaleza volatil de bitcoin, puede que no lo vean con buenos ojos. (Que poca fe le tienen)

Al final he encontrado quien me venda bitcoin a precio justo. El acepta USDT en la red de Polygon y por lo visto puedo comprar USDT a precio justo en otro CEX y solo cobra 1 USDT de comision por retiro.
Por ejemplo si compro 1000 USDT el la comision por retirarlo a mi wallet (Metamask) solo me costaria 1 USD, lo cuale es un porcentaje de retiro de solo 0.1% y a eso le sumo la comision de Polygon esta bastante barata entonces ahora si me he ahorrado bastante comision en compra/venta.

Digo al final si tambien depende de alguien me quiera vender Bitcoina a un precio Justo

No esta mal, ustedes que opinan?

340  Economy / Exchanges / Re: How can I trade on P2P On Binance exchange? on: October 10, 2023, 03:38:57 PM
We all know Binance is one of the best exchange in the world

The biggest yes, but the best i doubt it.

and there is a button called P2P Trade and there one can trade in their own local currency. I don't know how to do that so I'm asking for help from everyone. I hope you can explain me in detail.

It is true it have some pseudo p2p network, to do p2p trades you need to enter to https://c2c.binance.com/ logged in your account.

Select buy the token or coin that you want to buy, the currency that you want use (your local currencty)

Select the best offer that fit your needs, check reputation of the seller and time of response.

Select how much of that token or coin you want to buy and place an ORDER

Send him the payment to the account that is listed in the page with your local bank, usually bank transfer are allowed, but this may vary from one country to another.

wait for him to confirm the transactions.

If there is some problem you always can request support from bianance.

Regards!
