1201  Economy / Speculation / Re: BTC Sentiment Poll for October on: October 01, 2023, 01:28:39 PM
We've had enough red this past year that it is time for seeing some green candles now. Although we don't yet have the momentum but the potential is still there. Not to mention that every day when the market manipulators fail to push the price down despite their dumps, is a day where the buy support gets stronger Tongue
1202  Economy / Economics / Re: On Apple's $200 billion dump and US shooting itself in the foot on: October 01, 2023, 01:18:47 PM
This is the news I just read today, the China nightmare is getting worse for Apple, and US technology. China is increasingly serious about gradually eliminating dependence on American and Western technology. I believe that things will get much worse in the future when this American technology company's revenue depends too much on the Chinese market.
This is the whole point I've been making in this thread. Also keep in mind that the US dependence on others is not just their markets as export destinations, but also US depends on their resources to manufacture stuff they want to export.
For example we saw the significance of this in the sanction war between US and China where US started restricting export of chips to China and China started restricting export of materials used in manufacturing Chips to all those countries!

Hey guys. I switched Bitcoin Core to running on testnet. I have a couple of questions on that. I want to start solo mining tBTC. Can I prune the data when running on testnet? Or do I need the full blockchain db?
Yes, it is like mainnet. You don't need to store the whole blockchain, all you need is the chainstate (ie. the UTXO database) so you can prune the chain. But you still need to download and verify all blocks to build the chainstate before you can discard the old ones in the process called pruning.
1204  Bitcoin / Project Development / Re: Bitcoin Visual private key generator on: October 01, 2023, 06:17:29 AM
Thanks for the reply, but I was unable to find the zip file and run it locally, the clone you provided also didn't have the zip file, is it possible to run it on mobile offline? Doesn't matter if it works for mobile or not, just  a working page offline would suffice.
Go to the main page of the repository on Github and click the green button on top saying Code and then select the Download ZIP option to get a full copy of the repository. Then inside it you will find the html file called index.html that should be enough to run this and although I haven't tested it considering it is an html file it should run on mobile too.

BTW smart phones can never be considered "truly offline".
1205  Bitcoin / Wallet software / Re: Is using a remote node safe? on: October 01, 2023, 03:46:29 AM
I always use Bitcoin own node. I just want to know the risks behind using a public node ?
Your question is too vague., it depends on what you mean by "use" and "public node".

Nodes aren't categorized as "public" and "private". They either accept incoming connection or not.
As for connection/usage, if you mean something like connecting to a single node and syncing that way, it is not only a privacy risk but also a security risk since that node may be either broken or malicious and end up feeding you false data. This is why SPV clients usually connect to multiple full nodes for syncing.

In any case you should clarify your question for a more detailed answer.
1206  Economy / Economics / Re: Russia's economy is 'imploding' on export decline, economists claim on: September 30, 2023, 02:27:07 PM
The MiG-29 has good speed and slightly higher maneuverability, which gives it the ability to turn 180 degrees two seconds earlier, so the MiG-29 is good in close combat, but in fighter aircraft the advantage goes to the one who detects the enemy first.
The best modifications of Soviet (Russian) fighters with their onboard radar can “see” air targets at a range of more than 200 km and carry out air-to-air missile attacks at a range of 75 km. At the same time, the F-16 can engage air targets at a range of about 300 km and carry out attacks at a range twice that of the enemy, without entering the range of enemy fighters and ground-based air defense systems.

But what makes the F-16 even better is its avionics. Modern versions are equipped with the AN/APG-83 radar, which is simultaneously capable of tracking up to 35 targets and allows firing at 8 of them. In this case, targets can be both air and ground; there is no need to switch modes. At the same time, radars even on modernized MiG-29s (in Russian service) track up to 10 targets and allow attacking only one. And they are completely incapable of identifying ground targets. Moreover, the pilot must highlight the air target with radar before it is destroyed.
There is a huge assumption in your post. You are assuming that the F-16s that Ukraine is supposed to receive are the improved versions. However, from what I can tell this assumption may not be correct since what is being sent is the old versions with little to no improvement.

For example two of the batches that Ukraine may receive in the future are coming from Denmark and Netherlands. Both of these countries have purchased majority of their F-16s in the early 80's and some small numbers in the 90's; meaning most of what they are going to send to Ukraine is the old versions (A and B variants).

As for the lifespan, these old aircrafts have only gone through certain small upgrades for example one of them is what Lockheed-Martin refers to as the "MLU package" which Denmark paid for and only performs routine tests for fatigue, cracks, etc. and fixes some to increase the lifespan. It is like taking your 50 year old car to the shop to increase its lifespan for another decade!

As for the missiles, the only missiles that these countries have purchased (like the ones that RDAF owns) are medium range like the air-to-air missiles such as AM-110 that has a range of 30 miles (48 km), the air-to-ground missiles such as AGM-65 that has a range of 0.6-10 miles (1-16 km).

I couldn't find any reliable information about the radars installed in these aircrafts so I can't comment on that. But considering the rest, specifically the short range of their missiles, I wouldn't count on it to be anything "modern".

New iPhone 15 were sold out on Chinese platform Tmall within a minute after the start of pre-orders
PS Self-moderation is good, but why delete ordinary news on the topic ? Smiley
Just because some news has the word "Apple" or "iPhone" in it, doesn't mean it is on topic! Did you even bother reading the opening post or the ongoing discussion in this topic?
We aren't discussing iPhone 15 sale stats or speculating about Apple revenues here! At least read the article from BusinessInsider that I shared before spamming with irrelevant stuff...
1208  Bitcoin / Bitcoin Discussion / Re: They will probably use Loaded's coins for something within the next 12 months on: September 30, 2023, 07:08:48 AM
They may also want to get these coins used in a future hardfork civil war, probably after they establish the ETF and want to take control away from the crypto people and put it into the hands of the establishment via "deplatforming" BTC by removing it from exchanges and only allowing "Blackrockcoin".
In a "Fork War" in bitcoin which uses the Proof of Work algorithm, you'd need to have hashrate (mining power), full nodes and the community to follow you. Having a bunch of money and bitcoin is not going to really help in this decentralized network. It might have if bitcoin were using a shitty algorithm like PoS though Wink

Even targeting exchanges won't work because it is not 2011 anymore where 85-90% of the trading volume is in one exchange in one country to be able to have a significant impact on the whole market to have any influence using the price. Today the trading volume of different exchanges is low and mostly below 5 to 10% of the total volume and many of them are not even inside US for Blackrock to have any way of pulling anything like what you speculate.
Besides, market manipulation which is the only thing they can do, is not going to really affect any "fork war" that may or may not happen.
1209  Bitcoin / Bitcoin Discussion / Re: Several developers, miners, and researchers reported that Bitcoin mining develop on: September 30, 2023, 06:51:14 AM
Unfortunately, that's the outcome of complete decentralisation. As soon as the decentralied system becomes too large, mistakes and misunderstanding between nodes arise. In blockchain system it leads to forking (hard forks or soft forks)... Also, internet connection is a specific problem: miners do have high data processing speed, while connections between nodes don't. This also leads to information exchange problems, which eventually lead to strong need of centralisation, which opposes the whole concept of blockchain system. A loop is then repeated...
You should read the previous comments, specifically by @BlackHatCoiner. This had nothing to do with internet connection, data processing, orphan blocks, "misunderstanding between nodes", etc. And it definitely has nothing to do with being decentralized since the system is working beyond fine. In fact the reason why invalid blocks like this don't create any issue is because of decentralization.

This was simply an invalid block created a miner running a customized and buggy code.

The reason for things like this happening stems from incompetence developers who do not have a deep understanding of the Bitcoin protocol and its details such as the one leading to this mistake in the customized code the miner was using to create the block they mined.
We see incompetence like this from time to time too. For example a while ago we saw blocks that had too big an OP count that surpassed the allowed number and made the block invalid. Another detail that the developer who wrote the code for that miner didn't know!
1210  Other / Beginners & Help / Re: Some Trading Strategies You Could Be Ignoring on: September 30, 2023, 06:40:14 AM
4. Copy Trading:
Copy trading is often overlooked but can be a game-changer for those who wouldn't mind copying an expert's trade. This strategy involves replicating the trades of experienced traders automatically. By choosing a skilled trader to follow, you can benefit from their expertise without actively managing your portfolio.
This is the guaranteed way of losing money not a trading strategy.
For starters the real traders do no share their trades with others. There is simply no reason or incentive to do so. Anybody who does, is a scammer and their incentive to share their so called strategies is somewhere else, for example a pumper who wants to artificially pump a shitcoin they are bag holding would tell others to buy that shitcoin so that they can make profit.

Besides, even in best case scenario if you could find what the expert is buying you still wouldn't be able to do in different scenarios. For example an expert may buy a shitcoin but they know when to dump it and they will act quickly. But since you have no clue what to do, you will end up bag holding and lose money.
1211  Bitcoin / Bitcoin Technical Support / Re: How important is the witness data? on: September 30, 2023, 04:50:21 AM
But to correct your statement it is not removed totally from transaction but rather it is separated from it and moved separately with the transaction.
Witness is not "separated" at all, it is still part of the transaction and like any other field (like version, locktime, etc.) it is stored and transferred as part of the transaction.

The bitcoin block was actually 1MB which it is still the size
Max block size hasn't been 1 MB ever since the SegWit soft fork in 2017.
1212  Bitcoin / Development & Technical Discussion / Re: Given the first 15 words out of 24, can a hacker crack the wallet? on: September 30, 2023, 03:57:26 AM
If there are any security risks, please tell me. I appreciate it much. Thank everyone!
The main problem is the methods you use which can make things complicated and possibly lead to problems when you want to recover your mnemonic from the complicated backup.
For example you said "encrypt the other 12 words", what algorithm are you going to use? AES? Will you use a KDF like BIP38 to derive the password used in AES? Will you use it correctly and will it be reproducible? Will you remember how you did it so that you can recover your mnemonic in the future?
You see when you come up with your own algorithm, unlike BIP38 I mentioned, it won't be standardized so a lot of details about it could be weak, buggy or not-reproducible.
1213  Bitcoin / Development & Technical Discussion / Re: Is it possible to lock change by default? on: September 30, 2023, 03:42:15 AM
It depends on the wallet software you use. Some of them have the option to lock addresses or lock outputs (coins) manually. For example in Electrum there is the option to "freeze" addresses so that you can no longer spend from them even if you don't have enough funds in your other unfrozen addresses.
1214  Economy / Economics / Re: On Apple's $200 billion dump and US shooting itself in the foot on: September 29, 2023, 12:48:37 PM
Yes, the United States is still the world's number 1 power in many fields from economics to military, but look at how other countries are developing. It can be said that other countries are developing strongly while the US seems to be slowing down to let other countries catch up.

What is happening is similar to the Nokia empire, when Apple and Samsung were rising, they thought they were still kings until they were dethroned and withered away. Nothing is forever, the US has dominated the world for more than 100 years and it is time for them to cede it to others. Although America will not be dethroned any time soon, other countries are already taking action.
Good examples but there is a fundamental difference here. In case of all these companies we are seeing pure competition and they all continue existing side by side offering their products in a tight competing market. For example in a phone shop you see Apple, Samsung, Nokia, ... all there and you choose between them. That competition is a good thing since it forces all of these companies to keep improving and keep their product prices low.

In case of US, it was not the competition that got US to the "number 1" position in different fields. Instead it was destruction of others, some of which caused directly by US. For example the biggest help to US was World War 2 which only had one winner and it was US because US mainland was completely intact while everywhere else from Europe and Russia to Africa and Asia were destroyed. This is also what shaped the US general policy over the past 80+ years, a "grease the pol behind you" kind of policy.
This also clarifies why US sees any country that improves as a "national security threat"! Because if for example Africa regains its independence and strength, West Asia gets rid of US backed terrorists, etc. that means they will all kick the colonizers out which means all the resources US has been stealing all these years to build that "empire" will no longer be accessible to the regime for free.
1215  Bitcoin / Development & Technical Discussion / Re: A Script To Generate BIP-85 Child Seeds? on: September 29, 2023, 12:21:01 PM
Quick search resulted in at least two instances of JavaScript  implementation of BIP 85 (https://github.com/AndreasGassmann/bip85  and https://github.com/hoganri/bip85-js)
You should personally review the code you find by searching otherwise it may contain bugs specially in less popular projects. Otherwise stick to popular code like like Iancoleman source code or look at the BIP page itself, they almost always have a couple of "reference implementations" listed there that are more reliable than something you can find through quick search. Link to BIP-85 page (the second link you posted can also be found here).
1216  Bitcoin / Electrum / Re: are these all are receiving address? on: September 29, 2023, 12:06:31 PM
In addition to what was mentioned, you can open the console and type the following Code:

Code:
ismine("Your_Bitcoin_address")

This code will tell you whether this address belongs to you or not, but it is best not to reuse any old address for privacy reasons.
If you want to check if an address belongs to your wallet in Electrum, it is so much easier to just use the "hidden" search box in the Addresses tab from the UI, since it is more user friendly. All you have to do is to press Ctrl+F buttons on your keyword for it to appear.
1217  Economy / Speculation / Re: Bitcoin October Month Performance on: September 29, 2023, 07:51:18 AM
Considering that "what month it is" has little to no effects on bitcoin market I have to say that we can't predict the price like this. However, this month we have the increasing energy price and as we get close to another Hard Winter, for the second year we are going to see increased inflation and I don't think the increasing interest rates policy can help anymore which means this time the inflation won't be accompanied by recession and as a result bitcoin price can finally start going up.

As you can see, it is a big chain of events that is affecting bitcoin market, not just the month we're in and what happened in the past!
1218  Bitcoin / Development & Technical Discussion / Re: A Script To Generate BIP-85 Child Seeds? on: September 29, 2023, 04:05:02 AM
I'm just hoping to automate generation of BIP-85 child seeds with a script for fast access.
Since BIP-85 is not popular and what you want to use it for is not used by others, the "script" you are looking for probably doesn't exist either. You should write it yourself by using the existing code in Iancoleman repository for instance.
1219  Bitcoin / Bitcoin Discussion / Re: Banking scams ...How are Bitcoin better? on: September 28, 2023, 03:01:50 PM
Bitcoin is already fixing a lot of that by design. You see the reason why most of these scam methods like using card skimming devices, cloning your card, stealing your pin, etc. happen is because there is a middle man between the user (aka the owner of the funds) and the holder of the funds (ie. the bank). So the scammer comes in between as another middle man and takes the secret information during the communication between the user and the bank.

In bitcoin the owner of the funds and the holder of the funds (and keys) are the same. There is no middle man involved so nobody can use any of these methods to steal your secrets.
1220  Economy / Economics / Re: Is academic pursues enough to get incomes? on: September 28, 2023, 02:52:47 PM
I come from a country where their are no job
Then make a job! You don't have to become an employee, you can become an employer yourself. Of course it depends on your degree and your ambitions and how willing you are on taking on challenges and enduring hardship. For example do you think any of these big companies with thousands of employees (like Microsoft, Apple, etc.) were created out of thin air overnight? It took years of dedication and hard work to build the company to what it is today.

There is no reason for you not to be able to do something similar even on a tiny scale.
In fact if what you claimed was right, that means there is going to be little to no competition.
