¡Hola a todos!

Necesito algunos consejos sobre cómo comprar Bitcoin sin perder una gran parte de su valor. Aquí está la situación: compré algunos Bitcoins en CEX, pero cada vez que los transfiero a mi billetera no custodial, termino perdiendo alrededor del 7 al 10% de su valor, esto incluye las comisiones pro compra en red P2P dentro del exchange, retito y comisiones de red. Eso es mucho, y quiero encontrar una mejor manera de comprar Bitcoin en la que no pierda tanto durante las transferencias.

¿Alguien puede compartir su experiencia o sugerir una plataforma o método que ofrezca tarifas más bajas al comprar y transferir Bitcoin? ¡Realmente apreciaría su ayuda.

Gracias!

What? maybe is elon musk in the backend.

The only whay to proof that he is satoshi is signed a message with one of his address.

I'm going to take this with a grain of salt.

Es triste ver que ninguno de ellos es de mexico. 

Por cierto si fueran totalmente en crypto, deberian de cobrar en bitcoin o en algun shittoken. Los precios son literamente en fiat?

LOL,  PhD in stupidity or what?

There is no way to give negative merit? 

@nomachine what is the problem with the original code?


For Linux the best source of entropy is the internal RNG.


I strongly advice not use that code provide by @nomachine if you are using the program to generate your vanity addresses.

If the code is not going to be used for that and you are pretty sure that your machine have a RNG Hardware device the it is ok to use it

Hey everyone.

I need some advice on buying Bitcoin without losing a chunk of its value. So, here's the deal: I bought some Bitcoin on CEX, but every time I move it to my non-custodial wallet, I end up losing around 7 to 10% of its value this include bank fees, exchange fees and network fees. That's a lot, and I want to find a better way to buy Bitcoin where I don't lose so much during transfers.

Can anyone share their experience or suggest a platform or method that offers lower fees when buying and transferring Bitcoin? I'd really appreciate your help! Thanks!

Hey, I'm a developer too! Welcome to the forum.

I wanted to suggest a great book for you if you're into Bitcoin. It's called "Mastering Bitcoin" by Andreas M. Antonopoulos. It's like the go-to guide for learning about Bitcoin. Mastering Bitcoin by Andreas M. Antonopoulos

You can actually find the whole book for free on GitHub. Here's the link:

What language do you know?

Why don't use faucets? Some faucets give you some good amounts near 0.01 tbtc

I already told you about the n0nce user faucet project: [For Developers] n0nce's Bitcoin Testnet Faucet [~10 tBTC].

If you post your address i can send you some testnet

Thats depend of your software wallet:

Example in sparrow, you can freeze and unfreeze specific utxos


My recomendation for that is to have diferent seeds depending of each source of income. Just to be sure to not mix them.

Also you can setup the change Address manually, my recomendation is always to use a new change address but some users believe the other way: Re: Using change addresses does not increase privacy, just fees

Testnet should never be used as network base for real application usage:

Acording to https://en.bitcoin.it/wiki/Testnet

15 days ago that happened again the diffculty when to minimum:

Interesting behaivor of TESTNET difficulty

I know that miners prefer transactions with higher fees, so a bigger bump can help make our transaction stand out when the network is busy. This can be important if we need quick processing.

But instead to replace a Transacction with an increment of 100 sat/vB or any other exorbitant amount why not only 5 or 10 sat/vB

Hi, you still want to exchange?

Ok, I see where the misunderstanding is between us. Yes I  totally agree with you in that example that you provide.

But the first time that i mention this:


It was exclusively for a RBF or FullRBF option, this is to replace a transaction that is actually in mempool, in this case if you already send a 1 sat/vB and you want to change the destination address for another address you need to send at least a new transaction with the new address and a minimum fee of 2 sat/vB, so each time that you want to make some change you need to increment you previous fee by 1sat/vB MORE.

I already tested it, if you send less fee, the transaction is going to be rejected with some error like this:


That is why I added a picture of some random transaction at that time, that transaction increments the fee like 100 sat/vB more than the previous amount. But only one sat/vB will be enough.

So again my question:

Is there some developer working for those organizations that can explaint why they do that?

to be deleted, moved to archive

What? Noo that is not true if you increment the more feee like 1.1 sat/vB insteat 1.0 sat/vB you don't save more satoshi, actually in that way you are going to spent more satoshis simple math like 1.0 < 1.1


That depend of your software wallet if they give you te opcion to specify the exact amount of sat to be send and also the exact amount of sat to be use as fee you can increment by any decimal point value like:

First image at 1.0 sat/vB fee is 215 sat



Second image at 1.03 sat/vB fee is 220 sat


@OcTradism where is the saving here?

He only copy/paste the original text-tweet linked on the same text

This is near to impossible, maybe the attacker can broadcast transaction that are already spent in the real largest chain.

But any invalid transaction is going to be dropped without problem.

Or maybe I am wrong how a fake transaction is done?

Esperemos no pase asi aunque esto dependedera del valor bitcoin contra su valor en fiat, si el valor de bitcoin sube mucho las personas apreciaran su valor y intentaran salvar cada satoshi posible.
