This is completely wrong. Sunlight does not work 24 hours a day and does not work 100% efficiently. Therefore, without a battery system, the mining farm will operate for approximately half a day, and to calculate Energy Production= solar panel per kW * sunlight hours per day * efficiency factor

Electricity is one factor, but you have the space, budget, cooling, capital recovery and need batteries because the mining farm needs to operate 24 hours.
62  Bitcoin / Hardware wallets / Re: How secured are Trezor Safe 3 ? on: April 27, 2024, 06:17:16 PM
I am not a developer and can't read the codes. So it depends on other developers reviews. So far, my research seems pretty safe using Trezor rather than Ladger. So for small amounts of funds, I will keep using Ledger since it is easy to use. I feel a bit complicated with Trezor and the large amount of funds I will keep in Trezor. But trezor seems to don't support all major currencies, like BNB. You have to use a third-party wallet for other coins. However it doesn't matter actually but a bit harassment. They should update their software, which should support all the major chains. 
It also applies to cryptocurrency wallets. If you are skeptical, use an old computer such as an airgapped wallet, where you remove the network parts and use a clean, open source OS. Trezor is better than Ladger, but Passport - Foundation Devices is the best.

Using Trezor with third party wallets like NEW wallet is bad for privacy but the transaction is still signed offline.

Banning app is not a problem as it can be downloaded from third party links, but it gives a bad signal to developers, as they will be less keen on developing services for privacy. But does US know that transactions in the Lightning Network are still P2P?
64  Bitcoin / Bitcoin Discussion / Re: How has Satoshi's identity never been revealed ? on: April 26, 2024, 12:11:04 PM
We know that he/they was/were using Tor, shy, cautious, and had enough experience to hide his identity, and what helped Satoshi is that talking about Bitcoin and interest in it began in 2013, 3 years after his disappearance, and it is difficult to find a service that records junk data for 3 years.

It was 2009-2010, not 2024. If Satoshi started Bitcoin today, it would be difficult for him to hide his identity.

You can verify in two ways hardware test or firmware test:

first, open the device and examine the dedicated HSM chip. It must be isolated from the Internet connection, and therefore, even if the hacker gains access to the device, will not be able to access the private key or to test the firmware code and then Update the Trezor device firmware for the code that you reviewed. This way you can guarantee that there is no programming line to send the private key to an external server. If you are unable to review the firmware yourself, you must trust others who reviewed it.

The market would be accessible 24/7 from anywhere in the world, eliminating the risk of server downtime or IP restrictions that could occur with a centralized market.

Secondly, the market would be crypto compliant, allowing for the democratization of purchasing goods and services with a non-fiat currency.

points you mentioned are good, but privacy does not necessarily mean decentralization, and managing a decentralized market will be more difficult than a central market. We value privacy, but it is difficult to find a lot of interest and success in a decentralized market, as the user will need to download the software and manage it, and the process will be slower than central services, and risk Restrictions are lower, especially if all goods are legal.

It's quite surprising that a newly launched project like BlackCardCoin (BCCOIN) is already listed on various mid-level exchanges (Gate.io, MEXC, Bitget & BingX). At the moment, for me, it's quite dangerous to entry in this token, because it's still unclear what chart transitions might occur in the future.
The domain's lifespan is 50 days, and it is true that the token has been listed on some exchange, but trading volumes are still very low. In total, only have 10 million. entire project focuses on $BCCoin instead of building solutions for Bitcoin payments and the cashback amount confirms that it is a scam.
68  Bitcoin / Bitcoin Discussion / Re: BlackRock for the first time after the launch of bitcoin ETF had $0 inflow. on: April 25, 2024, 03:20:01 PM
Fidelity's FBTC has two days of $0 inflows, ARKB had $0 inflows for 3 consecutive days, BTCO, it is normal after we were talking about large flows.
If it continues for more than 3 days, then we may say that something is abnormal.
69  Bitcoin / Project Development / Re: A fully decentralized marketplace on: April 25, 2024, 03:04:35 PM
If the goods and services you sell in this market are legal, then what is the reason for making it decentralized? I can understand decentralization in mixers and services that may need to enhance privacy, but purchasing goods and products may be linked to knowing the buyer’s address, which makes it difficult to provide a service of a privacy nature. The market can be implemented for digital products not physical goods.

They are promising a lot of profits, 13% Instant Starter CashBack, 10% on all Referrals, Simple KYC, 1000x Gateway! to buy $BCCoin, but I did not find any legal data about the company. They claim that it is a company registered in the United Kingdom with this data:


Code:
CRYPTO MARKETING LTD
128, City Road, London, ECIV 2NX. UK.
Company Number: 15571337

I searched for them and did not find registration data https://find-and-update.company-information.service.gov.uk/company/09094616/filing-history
It is best not to complete KYC with this service as it may be a scam.

There is already an active thread https://bitcointalk.org/index.php?topic=5263722.0 and https://bitcointalk.org/index.php?topic=5492293.0
It is best to lock this topic unless you want to talk about something specific.
The electricity factor is crucial because if its cost is high, you may fail to recover your capital.
72  Bitcoin / Bitcoin Discussion / Re: Samourai Wallet seized by the feds on: April 25, 2024, 11:21:45 AM
What was seized? domain name and centralized Whirlpool coordinator? They already had plans to shut it down and if more continue to update to Samourai Wallet 0.99.98i_dexwp or any fork of that wallet, they will be able to use Soroban without any problem.

What happened is that Founders And CEO Of Cryptocurrency Mixing Service Arrested And Charged. The authorities may have found the data of the centralized Whirlpool coordinator, but this should not affect Samourai wallet.
73  Bitcoin / Bitcoin Discussion / Re: World Of Crypto Has Changed in Last 6 Years. on: April 24, 2024, 03:18:36 PM
It may be necessary to start thinking about using Bitcoin only as a means of conducting transactions and preserving wealth instead of  trade out to fiat.
It is true that the procedures have become more stringent, but you can still do P2P trading, buying and selling products with Bitcoin.
74  Economy / Service Announcements / Re: Forget about exchanger search! Use BestChange! on: April 24, 2024, 12:26:11 PM
As fees rise there will be more demand for the Lightning Network, providing a bitcoin LN option will help a lot.

Searches for Lightning Network apps will increase and they will inevitably look for any exchange that accepts Lightning Network, providing it on Bestchange means more views.
75  Bitcoin / Bitcoin Discussion / Re: How much did it cost to mine 1 Bitcoin back in 2009? on: April 23, 2024, 02:15:59 PM
In 2009, the difficulty was 1 and the hash rate of a CPU was around 3 MH/s.

The average time in seconds takes to mine a block is estimated by: time = difficulty * 232  / hash rate

So, the time to mine a block of 50 BTC was about 1 * 232  / 3000000, or 1430 seconds. That means, 1430 seconds / 60 /60 / 50 BTC, or 0.008 hours per BTC.
1430 seconds is approximately equal to 23.83333 min, but the average time between each block in 2009 was ~ 13 minutes to ~ 18 minutes, which means the hash rate of a CPU used was higher than 3 MH/s. I searched for some old topics and found that types such as Intel(R) The Xeon(R) CPU and AMD Phenom(tm) were giving more than 6 MH/s which is what was mostly used for mining, giving us an average of less than 23 minutes.

76  Bitcoin / Bitcoin Discussion / Re: With fees no longer compensating are some miners shuting down? on: April 23, 2024, 01:14:48 PM
It happened when mining was banned in China. It took several months for the hashrate to recover, but since the difficulty is adjusted every 2016 blocks, mining pools during the 2016 block will be able to mine more blocks compared to what they did in the past.

77  Other / Beginners & Help / Re: Do Miners still continue? on: April 23, 2024, 12:26:02 PM
Halving is a recurring event with predictable results, so all mining farms make their plans and have a vision of what will happen. Therefore, halving does not affect miners as much as prices affect them, as very low Bitcoin prices are harmful to miners and the unexpected legal legislation, as 30% tax that is being discussed.
78  Other / Beginners & Help / Re: Any portal to see OP_RETURN messages in readable format? on: April 22, 2024, 04:56:59 PM
These blocks were mined before Inscriptions and you will not find any useful data in them, extract the OP_RETURN data from hexadecimal to ASIC or UTF8.
There was a project for a site that helped you for full text search engine for Bitcoin, but it no longer works https://bitcointalk.org/index.php?topic=5450316.msg62154972#msg62154972
79  Bitcoin / Development & Technical Discussion / Re: Any of you sent a message @ Block #840000 through OP_RETURN? on: April 22, 2024, 04:44:08 PM
Mining pools were competing to broadcast the block first, and with the fees being worth much more than 3.125 BTC, the mining pool would not have time to broadcast a private message. It is not an important event as much as the profit that can be made.
about OP_RETURN, You can find the data here https://ordiscan.com/block/840000

That's right, the device is not protected from shock, fire, acids, floods, hurricanes and volcanoes, as well as any other influences. This device is intended for temporary, non-primary storage.

True, this is closed source, but I wanted to ask you. Let's say there are backdoors (on a 20-year-old device), then how will the data stolen by them leave this device without a wireless connection?
The lack of encryption means that if a friend next door or at the airport notices it, will try to read it. Humans love to snoop and read other people's diaries, and the old design may attract attention.

Some of these devices contain a USB port, which is sufficient to transfer data, especially since the programming of these devices is old and we are talking about unencrypted text content.

I think that some old multifunctional calculator is capable of storing 12 words without USB port and burned code, with the ability to hide them easily. it will be Best option
