Copper is a good conductor of electricity and heat. It is malleable, I don't know why I chose it, but taking the tests would be fun. I will add it later, but it failed a plantation failure, I am planning to add some devices away from the iron and steel parts. There is one on Amazon that I actually think is pretty slick-looking, and I've had it on my watch list for a long time. I don't think I'll ever buy it, but it's aesthetically pleasing to my eye (lol). As I said before, if the moving parts are not tight and the design is stiff, the device will fail. Do not waste your money. |

My Blockchain BTC wallet balance disappeared almost 2 days ago. I tried refreshing several times but says timeout or error fetching balance. I tried recovering the funds yesterday by creating another wallet, my balance appeared for couple of minutes and disappeared again after receiving and sending coins. I have contacted blockchain but no response for over 24 hours. Can I re-recover the funds using another wallet again? Would there be any implication doing that? Will I still find my funds in the new wallet?
Are you talking about Blockchain API? I don't think your wallet has been hacked, you having trouble recovering data timeout or error fetching balance. It is better to move to electrum, by following the methods above, and you can use it with API or use BTCPAY server if you have a website and want to accept bitcoin transaction. for electrum you can do it using JSON-RPC requests to electrum servers read more https://electrumx.readthedocs.io/en/latest/protocol-methods.htmland will do it using blockchain commands {

Disclaimer: The information's contained in this explanation is the result of my understanding of Ponzi Schemes and may contain some errors. Search and confirm about it.
Table of contents 1. Introduction 2. What is a Ponzi scheme? 3. How Does a Ponzi Scheme Work? 4. How to Recognize crypto Ponzi Schemes? 5. How to protect yourself?IntroductionMost individuals who invest in cryptocurrencies want make some profits so the return on investment (ROI) is supposed to be one of the things to study before thinking about investing. With the increase in projects and methods of investing in cryptocurrencies, the risks increased, and therefore risks must be redefined, the difference between them and Ponzi schemes. What is a Ponzi scheme?The name goes back to Charles Ponzi who became famous for his fraudulent system of earning money, as he managed to defraud hundreds of victims. Ponzi schemes work by paying profits to former investors with funds from newer investors and therefore the belief comes that profits come from product sales and thus continue to invest and the promise of generating high-value returns with little or even no risk. In the end, other investors discover that they are the source of the funds and therefore they will not receive returns and they may lose their money. How Does a Ponzi Scheme Work?The main point is that scammers never invest money that they redistribute investor money to believe that they are making profits, and therefore you need a steady flow of money to survive, otherwise they will run away with the money. What makes this type of fraud appropriate in cryptocurrencies is the fact that scammers are more difficult to track and there is not enough regulatory framework to protect investors and thus may escape all investments without paying any returns. How to Recognize crypto Ponzi Schemes?It is not an easy task, but there are some indicators and red Flags which make more likely the project is to be Ponzi Scheme than as an investment: - Promises of high profits with zero risk: “The higher the risk, the higher the reward” When you hear that there are no risks, something is wrong.
- Consistent returns, regardless of the market condition: The yield from investing varies according to the nature of the market, but when a project talks about double profits in a short period, regardless of the market.
- Lack of transparency: how to get profits, the nature of the investment, who the investors are, information about them. They try to sell you dreams without providing detail about them.
- Don’t offer real products or services: Often the investment is a dream, but there are no real services.
- Increasing minimum investment: These projects need to grow rapidly, and therefore they need to increase their capital, which is higher than the minimum withdrawal amount.
- It comes through someone with a shared affinity: Often these projects come from a well-known personality or someone you trust and thus reduce caution and search for them, sometimes they lie to developers or give false information.
How to protect yourself?- Be skeptical: Ask a lot, understand how you benefit from the investment, how the project works, read about them and ask people in this forum or who you trust.
- Do not trust. Verify: Do not trust the opinions of experts, and do not listen to all details without checking them.Ask for registration information, legal papers and verify that they are correct.
- Check out the seller, white paper, developers, their road map, and all the details: Scammers are always lazy so you will find some errors or misinformation.
- Understand the investment: Do not invest in things you know nothing about.

Source: https://thedailychain.com/russia-temporarily-drops-plans-to-criminalize-bitcoin/On July 19, 2020, local news outlet Ria Novosti reported that the Russian government had dropped its plans to criminalize Bitcoin’s use in the country. As per the report, references to administrative and criminal liability for dealing in Bitcoin were left out of the current Digital Finance Asset Bill (DFA), which is due to undergo its second reading in the Russian parliament on July 21. Anatoly Aksakov, the head of the parliament’s financial markets committee, explained that the notion of punishing BTC investors with fines and prison terms had been shelved, for now, adding that “there will be no liability in this bill.” Nevertheless, lawmakers can introduce a special law that will reimpose these or other sanctions during the coming fall. However, the revised DFA bill now seeks to deal with issues around the definition of digital financial assets and establish requirements for blockchain operations. All cryptocurrencies and mining operations remain in the gray zone. The Russian Ministry of Economic Development informed Parliament of its rejection of the draft law banning the cryptocurrency and made it clear in its following message: on June 11, 2020, the ministry stressed the need to change the crypto bill’s text to give room for regulation plans to govern the circulation of digital currencies in Russia.
As per the letter, guidelines for allowing businesses to carry out crypto-related undertakings should also be established. |

You are not obligated to use electrum, there are a lot of wallets and electrum is not ideal for all things. this wallet will fail if you want to generate thousands of addresses/transaction daily because it is not intended for that. For thousands of daily transactions you need more numbers, I can think of the following: Server: (hot wallet) - use blocknotify to updates balances to external database. - Script to check balance and update it (manually) if your hot wallet balance is less than X amount and move it (Auto) if your hot wallet balance is more than X amount. cold wallet: (Offline) - use Armory wallet that holds the private keys. - Admin access to refill your hot wallet. And if you don't trust the developers, do it yourself: You need cryptography library that supports secp256k1 ECDSA, generate your private key and use it to get your public key or Bitcoin address (SHA256 and RIPEMD-160) you can start with this topic: How Bitcoin Addresses are generated? Understand the Math behind BitcoinWhat is Elliptic Curve Cryptography? Understand how is it related to Bitcoin |

|
Fees are the reason. keep in mind that more bitcoin address = more inputs = more fees.Centralized exchanges are for profit, not privacy protection. Why do they lose more fees when they decide to move currencies from a hot wallet to a cold storage? So instead of wasting more money on fees, they give you a single address. example of 3 address with change address and without it: Change address: Each transaction contains a minimum of 79 vbytes. a total of 237 vbytes Without Change address:one set of 79 vbytes and save up to 45%. |

It's great, I checked the list, unfortunately some of the devices in the list are no longer available or the company has not succeeded in its development, I will contact him to update that list. I would also like to point out that the devices mentioned in this list are from steel only. I don't see any backup tool like USB disk, paper and cloud. Are you mean that tool isn't safe as backup tools?, I did back up using paper an as long time ago without any problem, low cost and easy to write without knocking hammer on a plate.
The reason I just mentioned Bitcoin is that I think 99% of the crypto currency models will not hold up for the coming years, so a small percentage will spend money buying devices to Hodl altcoin. Ledger and Trezor are Bitcoin & altcoin wallet. I don't think anyone will pay $ 80 to buy a device for hodling unknown altcoins. If you were to compare a USB stick or paper wallet with the above, then they have no chance if they are caught in fire or acid, or even water.
The above list shows that this idea is a horrible. 60% of above devices fail to protect your USB, especially against acids or fire. If you want to protect your devices and build them yourself, you need to use 304 Stainless Steel, remember to reduce the moving parts. I only ever use paper for my back ups, and I don't feel in the least bit concerned about this. As Lucius points out, paper will obviously perform very poorly when compared to these devices against fire, corrosion, etc. However, assuming that one of these devices is completely safe is incorrect. What if there is an explosion, and your back up is buried under tons of rubble? What if there if a flood or hurricane, and your back up is carried a few thousand meters away? What if it is stolen or otherwise inaccessible to you?
Given that, the only way to be safe is to be redundant. Everyone should be using at least two back ups in separate secure locations. Because I do this, I am unconcerned if I lose one back up due to fire, corrosion, or similar, and so I do not feel the need to use one of these metal devices. Laminated paper in an airtight and watertight container is good enough for me.
if you keep more than $ 10,000, spending $ 80 in enhanced protection is not a bad thing. Use Stonebook (€31,95) with a fireproof case ($29.) |

Bitcoin Seed Backup Tools
There are a lot of options for securing your wallet seed, here is a list of some of the options available with a quick feedback of them. Research Methodology: - Simplicity is always the best: the more moving parts of the device, the worse in some tests.
- 304 Stainless Steel is the best.
- Most devices pass the resistance test but are bad in temperature and wear, so try to reduce the number of moving parts.
- Devices that can withstand high temperatures are often bad.

new seed = new private keys. you can generate your own new wallet seed words and move your coins to it. If you want to create a new wallet seed just because if it's easier to remember for you (& others,) the idea is bad. There are better ways to secure your wallet seeds. you can create a custom wallet seed using brain wallet. (Risky) pick your own words from https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt and use this tool to generate correct checksum https://iancoleman.io/bip39/ |

Disclaimer: The information's contained in this explanation is the result of my understanding of Bitcoin Support and Resistance and may contain some errors. Search and confirm about it.
Table of contents 1. Introduction 2. What are Bitcoin support and resistance levels? 3. How to use them to predict the price? 4. OCO order with support and resistance levels 5. What is support-resistance flip? 6. Strength of a support or resistance area 7. Psychological support and resistanceIntroductionSupport and resistance are fundamental concepts related to technical analysis, whether gold, silver, or even cryptocurrencies. Being well aware of these concepts will bring you wealth, especially in a highly volatile market such as cryptocurrency markets, as it is one of the basic principles for everyone who wants to learn to trade. Above all, applying one of these concepts will not only make you accurate in predicting, but rather you will need to study a lot of charts. Understanding support and resistance will help you to understand more. What are Bitcoin support and resistance levels?Think about it, as if there are limits or areas that the price cannot exceed in the normal situation, and if it exceeds, it means that a big change will happen to the price. It is almost as close to a level as you can’t afford in the normal situation. In the case of support, the price finds "floor", while in the case of resistance it finds "ceiling." So, in a simple concept, look for support and resistance points, and when the price exceeds it, this means that a big change will take place, but real cases are usually inaccurate or simple by this principle, because the markets are not governed by strict mathematical rules of 1 + 1 = 2. Therefore, the most accurate concept is to think of it as a price range (zone) and not as fixed prices. Talking is easy. Why not move on to some practical charts? Notice that the price has continuously entered that area, but the price has not been able to descend below it and thus the price has bounced in the other direction. The same can be repeated for resistance levels. How to use them to predict the price?Many analysts use these levels to predict the paths of the market and because these levels are psychological and determined by market interactions in the past, they are ideal regions for large traders (or whales) to enter or exit, which means more liquidity flows to these areas. the risk levels are higher and hence the profit is greater, it is an ideal opportunity for those who want to achieve a quick profit because when the price reaches those positions either it bounces back up or down. If you are afraid of losing, you can place a stop loss order (OCO order.) If the area is breached, a buy or sell option is executed, thus traders can reduce their losses and exit with a small loss. OCO order with support and resistance levelsIt is one of the options that enable you to execute a pair of orders to buy or sell at the same time. to activate the option on Binance, click on "Stop-limit order" to open a dropdown menu and select "OCO." A practical example Let's say you just bought 2 LTC at 0.004 BTC because you think that the price is close to a support level and is supposed to rise. The problem is that you are afraid that the price will bounce and lose a lot of money. In this case, you can use the OCO feature to place a profit order at 0.005 0 BTC along with a stop limit order at 0.0039 BTC After that you search for the required support or resistance area and change the settings as shown in the picture. What is support-resistance flip?This pattern occurs when a resistance or support area is broken so that when the resistance area is broken and retested, it may turn to a support level later, and vice versa. In this type, the retest zone is ideal for anyone who wants to make a profit. Strength of a support or resistance areaThe strength of the support or resistance area represents the number of times the retest of that point is made so that the higher the price and the retest of the support area, the more likely it will be broken and thus expect a price drop that is likely. The higher the price price and retest the resistance area, the more likely it will be broken and thus an expected price increase is likely. Psychological support and resistanceIt is not related to any technical analysis, but a physical explanation, which is that the human mind tries to understand things in an aggregate form so that it is easier to assimilate the information. Suppose, for example, that people love numbers like 10 15 20 25 instead of 12 17 21 28, so rounding up these numbers will give you a higher marketing opportunity. The same applies to digital currencies, many prefer buying and selling at prices such as 9200 and 10700 and others instead of 9340 or 10670 and so on.

Is there any way for me to remove an entire unconfirmed transaction from Electrum?
AFAIK, yes you can do it with https://steemit.com/bitcoin/@profitgenerator/tutorial-how-to-fix-unconfirmed-transactionsIn short, it is Double-Spending, Disconnect the Internet, Copy the hash of the transaction, Create a Backup of the wallet, edit the wallet file with a text editor, remove some parts carefully to keep the JSON syntax intact, open the wallet (offline), Re-create the transaction, but this time put a higher fee and continue to broadcast the new transaction with higher fees. source https://steemit.com/bitcoin/@profitgenerator/tutorial-how-to-fix-unconfirmed-transactionsThe old transaction will be canceled and the new transaction broadcasted. you should be fast. In theory, it was a successful idea, but I did not try it. Press CTRL-F on the keyboard, and search for this hash in the file. It should appear 4 times, in different places, you need to delete them, but carefully to keep the JSON syntax intact, so I have highlighted what you need to delete, it should be different for you, but you will get the idea, it should be everything that is highlighted:
Here the section between the [] brackets needs to be deleted + the coma above.
This is the transaction data section, the TX hash and right below the data should be deleted, as highlighted above.
Delete everything between the {} brackets in the highlighted stuff + the comma after the brackets.
Delete everything between the {} brackets in the highlighted stuff + the comma after the brackets. source https://steemit.com/bitcoin/@profitgenerator/tutorial-how-to-fix-unconfirmed-transactions If it doesn't load, you need to restore your backup because you delete something wrong and you need to do it again |

is there a way to make a personal payment gateway using electrum ?
Electrum is not designed to handle a lot of transactions, if you want to expand to a few hundreds of transactions per day, it may not be appropriate. use my list https://bitcointalk.org/index.php?topic=5259548.0, Choose what works for you, according to the pros and cons. You can then withdraw your total payment to electrum or link them to the hardware wallet for more safety. It will be difficult to deal with the program to manage a commercial account, it is intended for personal use and needs a lot of addresses every day, which will increase the file size to hundreds of bytes or more. i tried it and my electrum out put cant generate qr codes larger than 760 bytes or so which mean limited number per day The client/wallet have limitations on how many queries it can send without producing issues with the servers. So if you're expecting " hundred and thousands" of transactions per day, consider BTCPayServer instead. Or you can run your own server and edit the parameters; follow this thread's solutions if you prefer Electrum: /index.php?topic=5261764.0the costs and edit the parameters will cost him more than running it using BTC pay server and he can get more than new features like refund feature or ln support which is not good in the last version of electrum. he can use it as cold storage and send output of daily to it. some Stores need more operations like taxes, discounts, withdrawals and other operating costs. Yes, Electrum could be use as a payment processor as already said by @OmegaStarScream. But since we don't know about your business or what you are going to sell and how large it, so I will suggest to read this thread where you will get multiple option, List - Bitcoin Payment Processors. From the list, I preferred for BTCPayServer as already said by multiple users. Otherwise, you may choose an appropriate payment getaway from there. Try to choose any non-custodial wallet for your safety. even for small business it will be hard to use electrum he need to run electrum server or will be locked due to DDOS attack |
