Do you mean how to schedule a transaction to be sent in the future?
It is easy. You can prepare a script to check your balance (bitcoin-cli and RPC) and then send to Y address on a particular day or every month.

the new update of https://btcpayserver.org/ includes the refund service^[1]. I haven't read how they did it, but you can try the service and if you don't like it, the money will be returned to you.

Cutting and assembling the private key in this way does not seem like a wise idea. For example, if you have a private key and cut two parts and someone reaches one of the parts, this does not mean that the time taken to brute-force your private key will be half, but will reduced by 2⁶⁴.

So it is better not to do that, you have to pay attention to where I put the parts and losing any part will make brute-force it much easier.

I recommend using ----> Secret sharing^[1]

Depending on the available budget, it is better to employ a dedicated support team to create a platform from scratch because safety is a vital option, that is, any hack that may lead to a loss of depositors’ money.
Scripts will be full of backdoor and you may hacked by someone who sells script for you.

you can start with some projects:

https://blockset.com/

https://www.rubykube.io/

I read somewhere that Purse.io is still working, so you may need to check it again.

What kind of products do you want to sell: AFAIK:
 
https://glyde.com/ : sell Cell Phones and Withdraw using bitcoin.
https://www.reddit.com/r/BitMarket/

Use escrow services and post links on Twitter, Facebook, Reddit etc.

Bitcoin is a good model against inflation, so no one will adjust the fees monthly to pay the service because it may equal more than 10 dollars, and the price increases in the future, so you will not find a person willing to pay 120 dollars a month knowing that their value will become 200 dollars after a year.

I don’t know why some comments talk about paying manually, it can be done automatically every month without having to pay manually.
Why not solve the problem by issuing a balance in BTC and USD?

The aspect that you should focus on is fees and add many payment options available.
If the service is BTC-related, make it unique.

Great work.
The orange looks great as the resin gives it a luster, how long will you keep it outside?
What is the final weight, is it heavy?

If you add some lights, they will look beautiful in the evening, and a frame can be added to them.

It's fun, but it's hard to read a public or private key so it's best to avoid the idea of ​​engraving a private key and try to include a smaller version of QR code.
If you want to use silver, it is better to search for adding more anti-oxidant properties because it will make reading the public key difficult.
If you can find a design that combines the three models, it will be amazing.
A QR private key, split into two parts, which will enable the user to spend money if s/he collects the two parts together.

Can you explain in more detail what exactly you are looking for?   Do you mean the difference between the number of times a person checks address and the number of times he uses it? or you mean blokchain.info?

anyway, Electrum works differently from other SPV clients.
Also, I do not think that there will be useful data that can be found through SPV clients, perhaps the only data is useful for blockchain analysis which violate someone's privacy.

Thank you, I can do it but the problem is the time, I am busy these days and it is difficult to find some time to do the designs as my other PC is far from me.
I can make signature designs because they can be done using any device.

Generally, thank you, when I have free time, I will contact you and I can do it for free.

I managed to find some Airvpn codes with a good discount earlier this year so I want to sell them here at half price.
You will get codes for three days or half a month at half the price that appears on the site.
Please contact me to see if it is possible to get a longer period.
Regarding escrow, you can trust me, but I am ready to use any reliable one.

even the price have more than 200 difference. I searched for the username on Twitter and the last tweet was since 2012.
There are also many pictures. Why didn't you include your bitcointalk username and more details?

the same type of Supreme x TNF BAMN JACKET was sold for about 1300 dollar.

Zelle/Venmo/PayPal are all reversible payment methods, so dealing with them will be dangerous.
If you send Bitcoin (ir-reversible) and accept Zelle/Venmo/PayPal, you bear the risk that the other party will not reverse the transaction, so it is better to do it with trusted people and you avoid doing that with untrustworthy people.

Good part: You can do business with anyone and you do not need to be trusted or have an old deals record.

There are no secrets on YouTube, and everyone who participates in any course, no matter how much, will not get $ 10,000 a month from just making videos.
Those who get this price are those who get followers with more than 10 million subscriptions, but given that they are few, it will not be a single training course that will be useful to them.
Stop lying and don't trick some people into making a quick profit.

Warning: Check the trust for this user. >>> Trying to scam $2,000. "Act fast or you will miss out!"

Stop lying, I'll give you a little hint that you are lying, The smallest size of wallet.dat file is about 90 KB, so how can you create wallets with sizes less than that? You are viewing .dat files, not compressed files?

Source of info


So, about half of the data you sell is not for wallet.dat files.

Going back to the rest of the files, it is impossible to brute force password if it is not easy (numbers and some words) and you know a part of it, otherwise you waste the hardware resources. Can you open those files and view the amount of money with them?

Finally, even if it is of economic benefit, you can achieve more profits by using some walletrecovery services.

I am asking about these offers, which cannot be obtained through other the American .EDU?
The reason for this is the difference in price. The price for some EDU emails offers is around 1-4 dollars, while the price you have is more than 10 dollars. What is the advantage other than that it is suitable for those who live in the UK.

AFAIK, most of EDU email can be used for Amazon Prime / Azure Student / GitHub Student / 1TB Office365 Email /Adobe Discounts, ...etc.

Do I need some personal data or just EDU emails?

I will try to summarize some of the information provided by Fidelity Center for Applied Technology (FCAT) to provide more data and analysis on Bitcoin mining Read it here ---> Bitcoin Power Analysis Hashrate Implications and Miner Economics.



Section I: Bitcoin Power Capacity Analysis: How much, where, and at what price

It has been estimated that the Bitcoin mining industry has access to at least 9.6 GW of power, assuming that all of the Hashrate that remained on the May 17 trough was among the most profitable new generation of mining platforms - the "S17 Class^*" and all devices that were shut down between May 10 - May 17th were from the older generation, and the "S9-class^*"  less profitable machines.

We also assume a PUE (Power Usage Effectiveness) of 1.12 across all relevant calculations, which means that for every 1MW used to directly mine Bitcoin, another 120kw is used to run everything else, including cooling systems, lighting, servers, switches, etc.



We assess that the BTC mining industry utilizes ~67% of 9.6GW available power capacity, growing at ~10% per annum, powering 2.8mm dedicated Bitcoin mining rigs.

Estimated mining capacity is roughly 50% in China, with the US accounting for another 14%, then Canda, russian,..etc


In our assessment, 50% of Bitcoin mining capacity pays 3c or less per kWh. it means lower revenues, and consequently, miners who have high energy costs turn either to lower energy cost areas or shut down.



Thus, the average monetary cost of 1 BTC mining is around $ 5,000, with a maximum confidence of approximately $ 6000, without other expenses, depreciation, and other costs.
However, there is a small percentage of bitcoin that is extracted at a higher cost of cash than the current price of bitcoin, and a minimum of $ 14,000, and perhaps the reasons that drive them to continue are energy purchase obligations, among others.


We note that the S9 class needs less than 2c/kWh to reach even in the current Hashrate network, and it is likely that you will need lower energy prices in order to remain sustainable while Hashrate continues to increase.
If mining with S9 class rigs, it would take about 70 devices and over 100kW, and correspondingly more maintenance and operations labor cost and power overhead to generate the same 1PH/s of Hashrate



Section II: Some surprising conclusions on the relationship between Hashrate growth and China’s flood season

The Southwestern provinces of Sichuan and Yunnan face heavy rain from May to October, causing an increase in hydropower production during this time and thus selling at cheaper prices (Where it is paid about 1c / kWh.)

As shown in the graph below, there is a noticeable difference between average price gains during flood and drought seasons


capital accumulation followed by equipment purchase, delivery and deployment is reflected more broadly in the correlation between price appreciation (which supports capital accumulation) and Hashrate growth 4–6 months later




Section III: Bitcoin Hashrate Growth Projections: How much, by when, why, and what could slow (or accelerate) growth.

Bitcoin network can exceed 260EH/s in Hashrate in the next 12–14 months, led by a modest increase in available power capacity from 9.6 to 10.6GW and an upgrade cycle that will replace older generation S9 class rigs with newer S17 and next-generation S19 class rigs


We believe that a low 3 nm capacity and potential initial low yield will lead to 5 nm operations is the mainstay of ASIC development and production until 2022. For these reasons, we believe that the S19 class excavators will account for the bulk of the shipments in the next 24 months,


So if the Hashrate network increases, the miner's share of the Hashrate total and thus Bitcoin flow decreases. If Bitcoin does not rise to keep pace with the increase in Hashrate, profitability will decrease and a new balance in Hashrate may be created significantly lower than our expectations here.


The dollar value of mined BTC will decrease over time, which will decrease profitability unless Bitcoin price goes up enough to make up for it.

Current Target Network Hashrate ~ 124EH / s and current BTC price of $ 9220, daily revenue per PH / s is ~ $ 70. If the Hashrate network would rise to 260EH / s, as we expect during the summer of 2021, Bitcoin would need $ 19,500 in order to have the same $ 70 in daily revenue per PH / s



What if the price remains the same? At what point will Hashrate not grow? If the power price is 1c/kWh, the S9 drilling rig can continue to operate up to 180HH/s Hashrate Network. At 3c/kWh, the S19 series devices can maintain operations of up to 295EH/s.

However, the devices will fail to recover the capital cost in Hashrates much less than 295EH/s.


If Bitcoin's price will steadily rise to $ 19k in two years at 40% + annually, then S19 class platforms will remain viable even at 5c / kWh power cost

The design looks elegant, I liked the idea, and the choice of colors and their reflection inspired the Japanese anime in the 1990s, like Girls und Panzer.

What I didn't understand is why is there a mouse at the bottom of the image? I thought it was an indication of corruption, but the content of the photo did not show wasted foods or such details.

What kind of tanks appeared in the picture? I thought they are FV4034 Challenger 2.

The price is bit high but let's wait for @selassiesoildier report.

Each type of exchange platform has its pors and cons. Central platforms with high trading volumes and a lot of hosted coins/tokens will be central and need to verify identity because they run millions of dollars in an economic activity. Using platforms with high trading volumes makes you less risky of losing your money because they are earning a lot and are afraid for their reputation.

decentralized platforms are good for people who want to hide their identity, and therefore lower trading volumes and more vulnerable to fraud.
Some of these platforms are open source like bisq and some do not require verification of identity like https://flyp.me/en/#/.

If you want to conduct trading with little money then you may choose one of those sites ---> https://bitcointalk.org/index.php?topic=5218464.
