First things first, move this to “electrum”.

It is not possible to extract private keys from a signed transaction. A signed transaction is consisted of some fields;

• The version of the transaction data structure.
• The input count.
• The inputs.
• The output count.
• The outputs.
• And a locktime.

An example of a signed (testnet) transaction looks like this:

0200000000010246424e9ea69f0f68e24923f620cdcb7265ba5d8b6d8d42cbbff3f97047bf0e120 000000000fdffffff4d7cf1e1b72fe276f2886f2676b8e72a8a5c5dbe042615b349461647ed4155 e90000000000fdffffff01066c1d000000000016001412752d46dffcef2ae3c917c303c84b63ae3 e083d02473044022046cf098e3e9ae1de57f0da0e8a77615bf0c317646aa45ad92bc65f85bffff5 f6022047fb56c7f5e9e432261b6b435888defccbe69f5dd23c8ddbda52e979f589a05701210216c 2975cad38bc2a409afa5dd4a990c464c4ac3beac05e0157f1c7e2653b7a100247304402202f09b7 3fa21c545e5ab77433b0aa9392debb365cdf7f88d7bf890231fec2b46002204b42115c384582bca 11f834c41b4bdf6baf8172ef18e662235ac00d26449debb012103cf5d183b63d97e8691e948fe47 0454e825ee34164923b957d17539a9398670621b9a1e00

As I said, there is no private key, the fact that you provided a valid signature is enough to prove the ownership of the inputs. The whole system relies on that signature and that you don't have to provide any private keys in your signed transactions.

So no, even if the online PC is compromised, it is not possible to extract any private keys, neither change the amount or the destination, because that would make the signature invalid.

There is a proven way to store it securely. There is no proof that it'll remain in the same place, that's why you have to maximize your security. I consider the paper way, the most secure; you don't store anything electronically and thus, you're proving to yourself that no malicious party can access your money. If you worry about your computer's RNG, roll a dice instead!

Write it on a paper or on a steel. Create back ups, so that if you somehow lose your main steel/paper, you'll have a way to restore it. Don't memorize it; burry it in the ground, hide it inside your walls, be creative!

You misjudged me. I didn't say that scammers shouldn't be caught or we should stop exposing them; if anything, it's pretty obvious that scammers should be busted and I encourage every user from every marketing forum existing to fight them. What I did say is that trying to stop someone from making shitposts is a loss of time, which is different.

You should fight for plagiarized papers, but how can you stop a guy like the one below from making non-stop meaningless posts?


You can't. Even if you report them with accuracy and get it banned, he'll just create another account and continue doing it, if he hasn't a hundred left. You'll just ruin your time. The solution for this problem is to cut his incentive, which would mean manager responsibility.

A mixer isn't a security measure, but a private one. Remember, if you mix your coins, you're making tracking useless; you will receive some inputs that have no connections in the block chain with your outputs and thus, you've succeeded on staying private from a block chain analysis.

In Bitcoin you cannot be anonymous, but only behave pseudonymously for the reasons I explained above. If the destination, the amount transacted and the date were completely unknown, you'd have accomplished anonymity. If we exclude the fact that each banknote contains a unique code, then cash are completely anonymous. In the cryptocurrency industry, monero is private & anonymous.

Satoshi was having a discussion with a forum user about Bitcoin's fungibility, but he/she then disappeared and the project was stuck with that consensus. Usually the creator affects the project's operation, unless there is no creator left.

Yep, that is very important. I'm afraid that the majority is unaware about coin control and that's justified; they shouldn't understand Bitcoin in that technical level. Those things should be automated for the average user which leaves me the conclusion that Bitcoin is a bad privacy oriented currency for the majority.

Lightning Network: a second path towards centralisation of the Bitcoin economy

Have you read this paper? What's your opinion?

True, Bitcoin is censorship resistant, but what I want to define here is that someone may reject accepting your bitcoins. There are cases where exchanges will reject your mixed bitcoins, whether if it's from a mixer or coinjoin-ed.

The address from a scam site that has 10 BTC will soon be blacklisted and thus, that money will be censored. Sure, no one can move your coins, but if the majority of the places that accept Bitcoin simply deny your deposit, you're essentially censored.

Reserved.

I think that the beginners should know the differences between those two. People tend to confuse them or consider them the same, but they have a very different meaning. I intend to compare them with Bitcoin each time to make it clearer.

• Privacy

Privacy is the ability of people to seclude information about themselves. In other words, it is the right for someone to not be subjected by unauthorized invasions such as government's. For example, a corporation may want to receive your personal details to serve you the appropriate advertisements. Google invades your privacy with AdSense; if you watch a video or google a sentence about “Pets”, you're most likely going to see Pet Shops/Food/Toys whenever you find a google ad.

In Bitcoin, your privacy can be invaded. Let's say that Charlie and Bob received 5 BTC from Alice in a transaction that looks like this:

1ALice...   10 BTC --> 1CharLie...  (5 BTC)
                       |  --> 1Bob...        (5 BTC)

Alice & Charlie now know that Bob's address is 1Bob[...]. This means that if Bob chooses to transfer these 5 bitcoins, he can be tracked down. Let me give you another example; let's say that Bob wants to get rid all of his bitcoins by selling them into an exchange. He chooses to combine all of his inputs and create one output.

1Bob...   5 BTC --> 1Exch4nge... (25 BTC)
16Uw...  2 BTC
1Ku8...   8 BTC
1HA8...  10 BTC

Alice & Charlie can now observe that the signer of the address that received 5 BTC previously is/was the owner of three addresses with 2, 8 and 10 BTC. Even if they don't succeed on finding that the receiving address is an exchange's, they already know too much. Bob is exposed and every transaction made from any of his four addresses can be censored by individuals. In other words, if Bob made an illicit activity from the 1Bob[...] address, they will all be considered what we call “tainted bitcoins”, because they were all in possession of a criminal. Even if someone made a completely legal transaction with Bob, he or she will be censored. People use mixers or/and mixing protocols to enhance their privacy.

Here's a nice technical thread to read: [Education] Bitcoin Privacy and Anonymity

• Anonymity

Anonymity is when the identity of a person is unknown and there is no technique that could identify or reach him. On this forum, I'm registered by the name “BlackHatCoiner”, but if my IP got leaked somehow, you could theoretically use a technique to reach information about my identity. So, am I anonymous? No. An example of anonymity that happens in real life is free elections.

In Bitcoin, while your addresses don't reveal anything about your identity, the block chain shows the transactions you make, the amounts transacted and when they were made. If you ever wanted to purchase something from a store and you used an input of 10000 BTC, the seller would now know how many bitcoins you at least have. So, is it anonymous? No. It's pseudonymous.

So, privacy is a concept that describes activities that you want to keep them for yourself, privately. On the other hand, anonymity is when you want from people to know what you're doin', you just don't want them to know that it's you doin' it.

• Anonymity is when you donate to a charity using cash.
• Privacy is when you lock the door in the bathroom; not because you have anything to hide, you just need to keep the activity there to yourself.

Open your cmd. Change the directory that is located to:

You could check it from your windows explorer too. Type the following to start the daemon and then hit enter:

Run the CLI with:

The GUI runs the daemon; this is the actual Core of Bitcoin.

Nice predictions, OP.  
Watching.

It seems to me that you don't understand the difference between a bank and a lightning node. The bank can transfer your money whenever they want; they just attempt not to. The lightning node cannot move your bitcoins same like I cannot move your bitcoins from your address.

I guess that the “C” in your username stands for “Chatter”?

If you extended your seed phrase from 24 to 50 words, it wouldn't make it more secure in a case of a brute force. The attacker would have to either search among 2048²⁴ or 2048⁵⁰ different combinations. But, an attacker wouldn't need to brute force any of the seed phrases above to steal your money; he'd find it less demanding if he went straight by brute forcing 2¹⁶⁰ RIPEMD-160 hashes.

Quoting one of my posts:

---

I believe that the seed system works fine. You shouldn't think about a dictionary list with more words, but rather with bits. A twelve words seed phrase is a 132 bits representation in BIP39. A twenty four words seed phrase is 264 bits representation. I highly doubt if these numbers can be characterized as “weak”. Same for RIPEMD-160 hashes.

Estimates are estimates. Would you risk your $100k hard earnt money to an estimate that you'll have $650k profit in late 2022? Others estimate that it'll reach $1M by the end of 2024. There is no answer to what will or may be worthing one Bitcoin in x years. A country just made a legal tender with Bitcoin and there are others coming too. Judge by yourself.

No one knows the future.*

Speak for yourself. From my perspective:  Who doesn't want profit?

You can't force anyone to do anything. It's a free discussion board and if you feel that they're shitposts report them. I'm afraid, though, that the problem is that you have nothing to gain from this procedure. These people don't even pretend to be interested in the topic and they want to get it done so they can get paid. If you report them, you're firstly losing your valuable time and secondly, you're just making it harder for them, but they'll keep repeating it.

I believe that if we wanted to get rid of the signature spam, we should look at the issue from its root, which is IMHO, low paying signature campaigns. A forum rule could be desired; campaign managers should be a little more responsible for those who hire. You can't run a campaign whereas lots of your participants get their posts deleted due to report accuracy and you aren't even accounted to it.

You mean a bear run? Surely not accordingly. There will always be miners that will find profitable to mine. Someone may had a $10,000 equivalent daily income and with the decline he'd earn $7,000. If we assume that he spends $5,000 for electricity everyday, he'll find it profitable to continue mining. But, my thoughts are that this is a minority of mining farms.

I don't believe that the security of a payment system has to do anything with its market value.

That phrase is how I'd characterize the cryptocurrency industry in the last 2-3 years. There is, indeed, manipulation, but that affects directly the supply and demand. If we had 100 people wanting to buy 100 BTC for $1 each and suddenly, 300 newcomers realized that they can get rich from this thing, it'd increase the demand, whether they'd have been manipulated or not.

I was checking the statistics center and I noticed this:


Is this some kind of forum bug? How can these users be 60⁺ years online?

The Bitcoin price is already based on the economic laws of supply and demand. We just need to measure it somehow and our fiat currency is one way. It is globally adopted and there is a force from the government to its usage. But, you can also measure it to other currencies and cryptocurrencies. Each one evaluates it differently, that's why there isn't a standard price.

The preferably chosen word “price”, instead of value, or the “market value” of Bitcoin is based only but its supply and demand. The fact that halvings occur or that the network becomes scalable affects the supply and demand analogously.

This is a common mistake. Its value isn't based on the difficulty. Its difficulty is based on its value. Think about it, if there is more demand and the price rises, the difficulty rises too, because mining becomes more profitable. If there is less demand and the price falls, the difficulty does too.

No, you're not. Nowadays, mobile phones record you to provide you the best advertisements. I once was talking about Star Wars Battlefront and after a while I got an advertisement about a cheap PS4... 

You should never trust a closed-source operating system with:

• Your voice.
• Your pictures.

No, taking a picture of your seed phrase isn't secure obviously. If someone gained access to your mobile phone, he could steal your money. If I were you, I'd just generate another seed phrase and I wouldn't try to memorize it or include it on any computer/phone. Just hide it in several places, so that if you lose one piece of paper, you can replace it with your back ups.

First of all, if an influencer ever said anything about Bitcoin it'd have a temporary effect and you shouldn't be happy about that. It's called pump and dump; Ronaldo's words wouldn't increase Bitcoin's value, they'd just make investors panic temporarily.

You, yourself, said that Coca-Cola stock regained its previous price. Same thing would happen with Bitcoin. A person can't affect the price of a commodity/stock in the long-term.

Are you generally informed of Bitcoin's intention? It's written in the whitepaper and it surely isn't made to be used as an investment regardless that it's being seen as an investment and as a store of value asset. I'm just telling you, because the reasons you mentioned have nothing to do with why you should invest in it. A greater response would be that it has lots of potential and countries have started adopting it; not those you wrote. Actually, the 2 & 3 you mentioned justify why it should be used as a currency.

I believe that his point is that the banks can steal your money whenever they want; the fact that they won't due to law prevention isn't the same with not being able to.
