Principles for the security of decentralized transactions of virtual currencies
#安全支付原则
The principle of safe transactions is that big must be big, and the payment process plays an important role in preventing funds from being stolen.
Let's use Bitcoin as an example. The core principle is decentralization, which has a significant impact on security. Centralized models like traditional banks or payment networks rely on access control and approval to keep thieves out of the system. In contrast, decentralized systems like Bitcoin put the responsibility and control completely in the hands of users. Therefore, network security is based on proof of work rather than access control, the network can be open, and Bitcoin transmission does not require encryption.

What role do the development of virtual currencies and projects play in the world? What is the potential for development in the field of science and technology?
The development of virtual currency and its impact on the world and its influence in the field of science and technology are huge
Global Impact
1. Financial system innovation:
• Payments and transfers: Virtual currencies offer a fast and low-cost way to make cross-border payments and transfers, providing new financial services, especially for those without bank accounts.
• Decentralized Finance (DeFi): Through smart contracts and blockchain technology, decentralized finance provides financial services such as loans, savings, and transactions outside the traditional financial system.
2. Economic transparency and anti-corruption:
• The transparency and immutability of blockchain make all transaction records publicly traceable, helping to reduce financial corruption and money laundering.

I sold everything at 2800, who will take over? 🤪🤪🤪... Finished after the fight.
Ethereum at 1400 is being ignored, while Ethereum at 4000 is being used to sell houses for all-in bets. Is everyone not buying Ethereum recently because they think 1400 is too cheap? #ETH

According to the latest information, Tether (USDT) will be delisted from cryptocurrency exchanges in the EU on December 30, 2024, due to non-compliance with the new regulations of the EU's Markets in Crypto-Assets (MiCA) Act.
CNYES NEWS
However, this change is limited to the EU region. In other regions, such as the United States and Asia, the trading and use of USDT will not be affected. Therefore, USDT is not completely exiting the market, but is subject to regulatory restrictions in specific areas.
It is important to note that Tether, the issuing company of USDT, has not obtained an electronic money license from the EU, which is also the main reason for its delisting in the EU region. Other stablecoins that comply with MiCA requirements, such as Circle's USDC, have obtained the relevant licenses and will continue to operate in the EU market.
Key point...
Therefore, USDT has not announced an exit from the market, but will be delisted in the EU region for regulatory reasons. For users in other regions, the use and trading of USDT will continue as usual.

When the platform and the merchant issue funds, the names do not match, which definitely means they are using illegal funds to pay you. Because the labels are reflected in the card in a timely manner, your card will be frozen immediately. 😂 According to anti-money laundering laws, you will be held responsible, and you are just a scapegoat for laundering money for others.
$BTC I seek help from my brothers to answer this. This is my first time making a large U transaction on the platform. I sold 190,000, and the real-name account of the merchant is different from the real-name account on the platform. When I attempted to release the transaction, I was prompted that the real names do not match, and I need to refund and complain immediately. Should I refund, or is this how merchants operate? I have no experience and don't understand. Should I release the transaction?

Popularizing Cold Wallet and Recovery Seed Phrase is an important part of cryptocurrency security. Here is their basic theoretical knowledge
Definition: A cold wallet is a device or service that stores cryptocurrency completely offline and not connected to the internet. The main purpose of a cold wallet is to increase security and prevent hacker attacks and malware intrusions.
$Features:
1. Offline storage: Cold wallets do not contact the Internet to prevent remote attacks.
2. High security: Because it is not online, it is almost impossible to be hacked remotely.
3. Physical security: requiring physical contact to access (such as hardware wallets or paper wallets).
scenes to be used:
Cold wallets are often used to store large amounts of cryptocurrency for a long time, rather than for frequent transactions. This method is suitable for users who want to put asset security first.

$BTC It is healthier to fall 😄 From the recent trend, we can see that most of the money is not in virtual currency
trading mechanism is not regulated that's my reason for playing with coins
The main reason why virtual currencies (cryptocurrencies) are more flexible and instantly available for inbound and outbound funding than foreign exchange funding is due to the difference in their underlying technology and operating model. Here are a few key reasons:
1. Decentralization and blockchain technology
Decentralization: Cryptocurrencies are based on blockchain technology and do not rely on a centralized institution (such as a bank or payment processor). This means that transactions

Hackers use cookies to steal user privacy and impersonate exchanges to conduct illegal transactions. Users need to take a series of preventive and countermeasure measures. The following are some specific defense and countermeasures: Measures that exchanges should take, and some suggestions:
Enhanced session management
Short session duration: shortens the effective duration of user sessions and forces regular re-authentication.
Activity monitoring: Monitor user sessions for unusual behavior, such as logging in from multiple geographic locations simultaneously.
Multi-factor authentication
Enforce 2FA: All users are required to enable two-factor authentication (2FA). Even if an attacker obtains the user's cookie, they cannot pass the 2FA verification.

#牌照 It has always been a top issue for virtual currency. I hope that the virtual industry can smoothly achieve mutual benefit and win-win results with the country. However, if it is included in the management, many problems will take advantage of the situation. It is really a contest between spear and shield. I hope that contradictions can coexist in order to achieve mutual benefit and win-win development.
Give some suggestions for the development of offline virtual industries in China. Play in a low-key manner and don't show off. A big tree attracts the wind! It will naturally have a negative effect on the big aspects.

3. MACD (Moving Average Convergence Divergence):
• DIF (fast line) is 623.00, DEA (slow line) is 961.80, and MACD histogram is -338.79.
• Negative MACD value indicates that the market momentum has weakened recently and there may be downward pressure.

🇪🇺 🚫 EU BANS MONERO AND PRIVACY COINS!
The European Union has officially passed the Anti-Money Laundering Regulation, setting the stage for a ban on privacy coins and anonymous crypto accounts starting July 1, 2027. Under the new rules, financial institutions and crypto-asset service providers will no longer be allowed to hold or manage accounts that enable anonymous transactions or support privacy-focused cryptocurrencies like Monero (XMR), Zcash (ZEC), and Dash.
The AMLR also mandates identity verification for crypto transactions above €1,000, aiming to tighten anti-money laundering controls across the crypto space. To oversee these measures, the EU will launch the Anti-Money Laundering Authority (AMLA), directly supervising up to 40 major CASPs across member states.
Supporters argue that these rules will curb illicit activities and improve transparency in digital finance. However, critics warn that banning privacy coins could undermine financial privacy rights and restrict legitimate uses for activists, journalists, and individuals in oppressive regimes.
This landmark regulation signals Europe’s commitment to stricter oversight of crypto markets while raising questions about the future of privacy-preserving technologies in finance.
Do you think this ban will set a global precedent—or push innovation elsewhere?
