3361  Economy / Service Discussion / Re: A Little way to find Good campaigns on: May 26, 2022, 09:27:53 AM
I do not think that the problem now lies in campaign managers, but in campaigns, it seems that we will not witness price increases, and therefore most campaigns will withdraw from the forum because few people care about Bitcoin, and therefore you will find that the number of new campaigns is less than the total of campaigns that appeared when all were Talking about Bitcoin (last year as an example)

The activity of signature campaigns may decrease during the next two years to increase again, but the preparation of such lists will help the owners of projects to compare.

Another much easier way is just keep following the thread that has an overview of Bitcoin paying signature campaigns (Overview of Bitcointalk Signature-Ad Campaigns [Last update: 21-May-22]

I remember there was a thread that tracked signature campaigns for altcoins but I couldn't find the link, it would be a good addition to the link above.

If you still believe that this project will come back, it is better that you provide your faith in something truly decentralized like Bitcoin because the centrality offered by this project says that it will not come back unless many investors put their money in it, and after this failure there is no reason to deposit money with them .


They are about to start it, I am thinking of getting in even just worth alittle amount grabbing 100K LUNA for the snap. If the price of v2 will be like $1, that's a very good profit. Its the possibility of it going to a $ will be doubted by many of the speculator.

According to the last I read, they will get rid of the concept of stablecoins, and then it will be only Luna coin (OLD LUNA and HardFork LUNA CLASSIC) with an attempt to pump the price to restore trust, in other words they admit the failure of their software.
3363  Economy / Service Discussion / Re: What role are faucets and freebitco.in playing in BTC mining? on: May 26, 2022, 09:03:44 AM
My question lies in the area of where these other faucets and freebitco.in get their coins from.

I think the members have explained to you the difference between mining and faucets but you have to realize another difference which is that all sites that claim to mine bitcoins are 99% scam.

Bitcoin mining is done by specialized devices, and you can read more here[1]. Honest sites buy bitcoins or buy mining tools to get bitcoins and then distribute them to users.

So where do these sites make the money? In fact, most of these faucets (honest one)  take advantage of either the clicks you make, the ads you see, or access your cookies and try to sell your data, thus generate profits and give you a portion of it.

Finally, you should know that these sites are databases meaning that they can claim that they have 30M bitcoins but in fact unless you withdraw those coins (there are only less than 21 million bitcoins) to your wallet, you cannot believe their claims

I bought a hardware wallet finally but honestly, you guys can't tell me that hardware wallets don't have any disadvantages, is it safe to just use them without zero worries or let me just ask by saying what are the Don't Do of hardware wallets?
Perhaps one of its drawbacks is that it does not give you false security that your coins are safe, so always DYOR.
Make sure that you have purchased a device directly from the company without intermediaries, that the device is locked, you have updated firmware, and that you do not use old seeds before.

After that, make sure that your computer does not contain viruses, and do not download or click on random links.
3365  Economy / Trading Discussion / Re: EW traders telegram channel on: May 25, 2022, 11:07:59 AM
Your problem lies in the members, the quality of the discussions and who to encourage the discussion, Telegram makes things quick and easy, but the problem lies in how to entice members to participate with meaningful posts.

Therefore, the best solution may take some time, which is to start participating actively here, get to know more members and over time you can ask them to join your channel and participate actively.

In general, such channels need patience and good management and will grow quickly.
3366  Bitcoin / Hardware wallets / Re: How soon can you send received BTC in nano ledger? on: May 25, 2022, 11:02:15 AM
What is the exact setting you are talking about here?  Back then when i used electrum years ago, recall when i had btc balance... when i would then later receive 0.05 btc and it show 0 confirmations on electrum, i would still be able to send 0.05 btc to another site etc.  But is this because i already have a btc balance? 
Remember you can't spend bitcoins you don't own and therefore creating a transaction (unconfirmed transaction) means that you want to spend that money, if you don't have it then that transaction is considered invalid.

So if you enable that option, and your last unconfirmed TX, for example, replaced with a new outputs using RBF, your new transaction will be invalid because you are trying to spend coins that you don't own.

In short, activate that option if you trust the party who will send you money, and you want to send it to an address you trust.

Note: If you do not use coin control feature, enabling this option may reduce your privacy.
3367  Bitcoin / Bitcoin Technical Support / Re: How many confirmations required for btc received to be safe from double spend? on: May 25, 2022, 10:27:44 AM
We cannot give a general answer to your question, but the number of confirmations required depends on several factors.


For example, I can divide them into:

 - The type of customer and the degree of trust in him: In the end, if you are dealing with an unknown customer to buy a cup of coffee, is not the same as dealing with an unknown customer to buy a car, not like dealing with a trusted customer to buy a house, but in general the possibility of reversing 6 confirmations is considered impossible in the normal situation.
 - Network status: For example, there are some rare cases such as soft fork, hard fork, sudden drop in mining, and others.
 - The nature of your activity: Economic activity varies, for example, trading platforms are looking for speed to seize opportunities, and therefore the number of confirmations varies according to the risk, but in general and for the speed factor, one confirmation is sufficient for most cases.


So in short and according to your system, you can divide the system into several degrees, trusted people need one confirmation for depositing, two to three for withdrawals and unreliable people with large amounts of money need six confirmations for depositing and ten for withdrawal.

Could a transaction still be cancelled after one or two confirmations?   Are there examples of this happening?
Yes, check ---> https://forkmonitor.info/stale/btc/666833 (Multiple blocks were produced at height 666833.)
3368  Economy / Speculation / Re: BTC -85% FROM ATH IN NOVEMBER..... on: May 25, 2022, 10:12:51 AM
The only rule that we may have learned is that the price is going against expectations. All expectations were positive during the last period and it is the first time, we started hearing about the possibility of returning to 20K levels or less, and therefore in the long term we are in a good position.

Unfortunately, the coming months are economically bad, and therefore I do not think that we will witness many positive things, but I really hope that we will get levels higher than 50K before the end of the year (meaning that the recession period of less than 30k will be next year)
3369  Economy / Economics / Re: Court rules SEC’s internal judges are unconstitutional on: May 25, 2022, 09:49:06 AM
I'm certain the question on most peoples minds is how to convince the SEC to greenlight crypto ETFs.
If you mean what Michael Sonnenshein Grayscale CEO is trying to say he's going to take a legal action against the SEC[1], I don't think that will increase the pressure on them or try to change their position.

Personally, if there is no change in the SEC then we should only expect further delays, they are taking the matter carefully and watching what happens in Canada, Australia and the Eurozone and then maybe it will be approved.

In general, Bitcoin is now moving negatively, which means that investors' appetite for risk will not be high, especially with the complexities that the world is going through, so we are not in an ideal position to agree to a new high-risk investment.

I wrote the system so that I can easily add additional paid memberships in the future, but I might not ever do so. Not sure.

It looks like a modified library that was used to generate addresses but I think most of the modifications come from https://btcpayserver.org/ ?!

In general, I think that the above project is open source and provides an option for everyone who does not want to strive to write code from scratch, and therefore @theymos is the one who can confirm the nature of the code.
3371  Economy / Economics / Re: Solar panels set to be mandatory on all new buildings under EU plan on: May 25, 2022, 09:20:15 AM
The only positive aspect that I see in this news is that all these opportunities and investments will develop the solar panels and batteries industry quickly and effectively. If these investments were able to manufacture batteries more efficient than lithium batteries at a price of up to a quarter, I think that the cost of solar energy systems would be greatly reduced.

In general, the adoption of solar energy in European countries is not a strategic option, but looking at the map below, I think that a lot of things will change in the next five years.

3372  Other / Beginners & Help / Re: Educational: Bitcoin is technically independent from Altcoins on: May 22, 2022, 08:46:48 AM
If we are talking about technical independence, all the altcoins are independent and only the tokens depend on the blockchain included in them, and this also includes the second layer networks, NFTs and others.

But at one point or another, we will find that most of the altcoins are similar and carry copies of the Bitcoin code with some minor differences, except for some cryptocurrencies that carry fundamental differences.
3373  Other / Beginners & Help / Re: Bitcoin 51% attack and its effect on: May 22, 2022, 08:30:27 AM
The topic title indicates "Bitcoin 51% attack and its effect " but you didn't talk about the effects, I can quote the effects from here ---> https://en.bitcoin.it/wiki/Weaknesses#Attacker_has_a_lot_of_computing_power:


Quote
An attacker that controls more than 50% of the network's computing power can, for the time that he is in control, exclude and modify the ordering of transactions. This allows him to:

Reverse transactions that he sends while he's in control. This has the potential to double-spend transactions that previously had already been seen in the block chain, affecting all coins that share a history with the reversed transaction
Reverse confirmations for any transaction that had previously been seen in the block chain while he’s in control.
Prevent some or all transactions from gaining any confirmations
Prevent some or all other miners from mining any valid blocks

The attacker can't:

Reverse other people's transactions without their cooperation (unless their coin history has been affected by a double-spend)
Prevent transactions from being sent at all (they'll show as 0/unconfirmed)
Change the number of coins generated per block
Create coins out of thin air
Send coins that never belonged to him

I think that the percentages mentioned above are not accurate, you can find more here  https://bitcointalk.org/index.php?topic=2227.msg30083#msg30083 .


Personally, I don't see that someone who would attempt such a costly attack would attempt to do so at a rate of less than 60% and would rely on luck while burning millions of dollars every second.


3374  Bitcoin / Bitcoin Discussion / Re: watch only non spendable balance on: May 21, 2022, 10:11:13 AM
please do anyone know how i can add a watch only address to my wallet?  

What do you mean by "watch-only addresses"? When you generate your wallet from seed you are generating an HD wallet from seeds, meaning you can generate multiple addresses/private keys from those seeds, and when you export your master public key you get the view wallet file.

You can list and track multiple master public key using third-party applications (bitcoin trackers[1][2]) and these applications also allow you to list individual addresses.

watch only wallet is useful in tracking your coins and cannot be used to prove anything, because the proof requires signing a message, which requires a private key.

3375  Economy / Service Announcements / Re: [ANN] BTCATH.COM - Tracking crypto all-time highs has never been easier on: May 21, 2022, 09:56:11 AM
I liked the interface, it's a little different from the pattern followed on most crypto tracking sites, and the concept of ATHs is suitable for some cryptocurrencies and to clarify that most of them fail to return to that top again (if we consider Bitcoin as a 191 day scale)

I was surprised that the number of coins that reached the top when Bitcoin reached the top was not a large number, generally if you add more filters we will get more accurate results.
Are you planning to launch signature campaign? Because I see you made a signature? Or is it an unpaid signature?
3376  Bitcoin / Bitcoin Technical Support / Re: [TESTED IT] Minimum transaction value on: May 21, 2022, 09:39:04 AM
Now we know that the lowest accepted value for segwit addresses is 294 sats.

I don't know, but since the term "dust TX" is client-specific and not network protocol, the statement above cannot be accurate.

294 sats is the lowest transaction that the Bitcoin Core software can accept and less of it is considered a dust transaction, but does not mean that it is the lowest transaction that can be broadcast in the network?! Huh

Overall, thanks for proving that such tx can be broadcast.
3377  Economy / Service Discussion / Re: Rising Popularity of Crypto and It's Growth on: May 21, 2022, 08:56:59 AM
Frankly, there is no growth, but spam. Growth refers to the new ideas that are being put forward in a market and most of the currencies you are talking about (18000 cryptocurrencies) are duplicate models of less than 20 cryptos with some lazy modifications.


Most of these coins are tokens that are created on Ethereum, BSC and other quick token development solutions that mainly aim to make developers rich.
As for the technical development of altcoin, it does not go beyond a few models, and the rest of the models try to repeat the idea.

I know 1 web suite and before was no problem to köpa bitcoin, but till finish, web site  tell them send all money, but i dond see them .
It seems that you speak Swedish (from the word köpa), so if you know someone who speaks English or any language in the local boards[1] it will help a lot.

If you have completed withdrawing your coins from the platform, you will get TXID, ask them and make sure that the data contained in it is correct.

3379  Bitcoin / Electrum / Re: Signing transactions in Electrum hot wallet while temporarily offline on: May 20, 2022, 10:54:52 AM
Is it possible to sign a transaction from an online Electrum wallet whilst temporarily disconnected from the internet?

The transaction is signed by the private key, so you can sign it without the need to connect to the Internet.
After you sign it, you can broadcast it through any computer connected to the Internet.

I turn off wifi before opening an electrum wallet but then need to connect again to get up-to-date fees. I try to disconnect from wifi again to sign the transaction but it doesn't seem to work, so end up having to enter password for signing when online.

What you do will not add security advantages to you as hackers can steal your coins, because the private key/seeds are present when you connect to the internet.

The idea of ​​cold storage[1] is that the seeds are created in an environment that has not and will not be connected to the Internet.
If you do not have technical experience, it is better to buy a hardware wallet.
If you can't afford to buy it, it's best to buy a USB, burn Tails[2] OS on it, generate seeds, and connect through it whenever you need to send your coins.
You can check this video about how to make Bitcoin cold storage and DYOR ---> https://www.youtube.com/watch?v=yzJ9bRFkwmo

Cryptocurrencies should be regareded as a course in marketing and taught in schools as a subject for marketing disciplines ,it will help build foundation and give a basic knowledge & understanding to the students and make everyone see how vulnerable cryptocurrencies have become.
Who do you mean by "should be regareded as a course"? governments? individuals? The international community? UNESCO? european training organization parents? the teachers? professors? the doctors? Elon Musk?
We are in a cryptocurrency forum and we all agree on that, but all we can do is invite local members of our community to vote to adopt laws that add articles related to inflation to classrooms and marketing workshops, with community awareness and try to open opportunities for dialogue about this and invite specialists to conduct seminars.
