According to a report by South Korea's "Daily Economic News," the Ministry of Economy and Finance has decided to classify perpetual contracts linked to U.S. stocks as overseas stock derivatives, bringing them under the scope of capital gains tax. Starting next year, profits earned from investing in such products through overseas cryptocurrency exchanges will be subject to an 11% tax rate, calculated after deducting a basic exemption of 2.5 million Korean won from annual earnings, which is half of the tax rate for overseas spot stocks (22%).The report states that U.S. stock perpetual contracts are derivatives traded through overseas cryptocurrency exchanges like Binance, tracking U.S. stocks such as Nvidia, Apple, and Tesla. Since the Financial Services Commission of South Korea has not permitted perpetual contracts, South Korean investors can only participate through overseas exchanges. According to industry statistics, the trading volume of such products across 19 global exchanges from January to August this year was approximately $1 trillion. The South Korean government plans to monitor investors' relevant trading records at overseas exchanges and tax them accordingly. The news cites sources from South Korean government departments, but has not yet received official confirmation from the Ministry of Economy and Finance.

Blockchain data analysis company Chainalysis stated on October 31 that addresses related to stolen funds from Binance are attempting to transfer assets before the stablecoins are frozen. One method they are tracking involves depositing stablecoins into DeFi protocols and then retrieving them with new addresses.Chainalysis indicated that this method appeared early on the Tron blockchain following the approximately $6.4 billion attack. The related operations first convert TRX into stablecoins, and then into tokenized deposit receipts. These receipt tokens themselves cannot be frozen, but holders can exchange them back for the stablecoins they represent. The company noted that North Korean threat actors have used similar methods in other cases, citing the example of the TraderTraitor organization transferring $500,000.According to Chainalysis, the related funds were deposited into DeFi lending protocols and received non-frozen deposit tokens, which were then transferred to a new wallet that was not associated and exchanged back for stablecoins, before being converted to ETH on Ethereum through a cross-chain bridge. The company also stated that Circle and Tether have participated in freezing approximately $2.8 billion to date. Chainalysis mentioned that converting stablecoins to ETH does not exempt attackers from being tracked, and its investigators are monitoring the related on-chain patterns in real-time.

According to the official account of the Supreme People's Procuratorate, a recent case involving U Coin fraud was heard in Xuzhou, Jiangsu, where Wang and others defrauded the victim, Xiao, of 1.2 million yuan under the pretense of purchasing U Coin. The case was initially transferred for prosecution on suspicion of robbery, but the procuratorial authority believed that Wang and others had meticulously set a trap, using false transactions as bait to essentially defraud the victim of U Coin, which constituted fraud. Therefore, they filed a public prosecution with the court.During the trial, the defense attorney presented arguments that the defendants constituted contract fraud. Whether the case is classified as fraud or contract fraud will result in significant differences in sentencing. The prosecutor pointed out that the criminal law stipulates that contract fraud is aimed at maintaining market order, and the contract content must reflect the attributes of a socialist market economy. Virtual currency transactions are illegal financial activities explicitly prohibited by the state and do not fall within the regulatory scope of contract fraud.

According to Bloomberg, on October 31, 2008, Satoshi Nakamoto released the Bitcoin white paper, proposing a peer-to-peer electronic payment system that does not require the participation of banks or central institutions. Over the past 18 years, Bitcoin has evolved from a marginal experiment in early dark web and forums to an asset class recognized by Wall Street and institutional investors. In October last year, there was still $19 billion in leveraged positions liquidated in a single day, and the crypto winter of 2022 caused the market value of digital assets to evaporate by more than $2 trillion.On the 18th anniversary of the Bitcoin white paper's release, the price of Bitcoin hovers around $80,000, facing its worst month since June.Today, the Bitcoin ETF launched by BlackRock has reached a scale of approximately $66 billion, with several publicly listed companies incorporating Bitcoin into their balance sheets. Traditional financial institutions are also actively laying out stablecoins, asset tokenization, and blockchain financial infrastructure. However, this development also brings a certain contrast: Bitcoin was originally intended to challenge the centralized financial system, but it is now increasingly being accepted by traditional financial institutions.
