The W bottom pattern is a common bullish signal on candlestick charts, characterized by two similar lows followed by a rebound. When identifying a W bottom, pay attention to the interval between the two lows, changes in trading volume, and the volume during the breakout of the neckline.

Investors should exercise caution.

The article analyzes the security and use cases of cold wallets and hot wallets. Cold wallets store private keys offline, offering higher security, but require careful management of private keys and seed phrases. Hot wallets are more convenient but carry greater risks. Investors are increasingly inclined to self-custody their assets, leading to a rise in cold wallet sales. For everyday transactions, hot wallets are suitable, while cold wallets are recommended for holding large amounts of assets.

Black Swan Suddenly Descends
Remember a few months ago when everyone was talking about the "Black Swan"? Well, it’s finally here. On October 11th, at 5 a.m. Beijing time, when Donald Trump announced the imposition of a 100% tariff on Chinese goods starting November 1st, the global financial markets instantly exploded. The S&P 500 lost $700 billion in value, and the Nasdaq dropped 3.5% — this was just the beginning.
The crypto world is the real bloodbath. Within 30 minutes, Bitcoin was crashing at an average rate of nearly 1% per minute, with the most extreme single-minute drop exceeding 4% (a $5,000 decline). It was as if an invisible hand was wildly smashing the sell buttons. Ultimately, Bitcoin plunged to $102,000, ETH fell to $3,400, and major altcoins like XRP and DOGE suffered even worse, dropping over 30%. In one day, $19.1 billion was liquidated — that’s a pretty significant scale.
Why does a sneeze in the US stock market cause a pneumonia in the crypto world?
It looks like just a tariff announcement, but...

The core of the Turtle Trading System lies in trend-following, risk management, and discipline. It manages risk and returns through mechanical entry and exit rules.

Successful traders are often those who can stick to the rules and stay calm under pressure.

Prediction: Trading platform Kalshi sues the New York State Gaming Commission, accusing it of overstepping authority by demanding the cessation of sports betting services, asserting that it is regulated by the CFTC. Kalshi previously obtained preliminary injunctions in Nevada and New Jersey and may also succeed in New York. This case highlights the power struggle between federal and state authorities in the U.S. If Kalshi wins, it could lead to changes in how multiple states regulate similar platforms.

The article discusses changes in the Bitcoin (BTC) market, suggesting that this cycle may break the traditional "four-year cycle" pattern. This shift is primarily due to changes in market structure and a decrease in retail investors holding coins. The article emphasizes that the potential passage of U.S. crypto regulation bills and global central banks' liquidity injections will attract significant institutional investment into BTC. Meanwhile, traditional financial institutions are beginning to recognize BTC's value. In the future, the supply and demand dynamics of BTC will fundamentally change, potentially gradually replacing gold as the mainstream store of value. Investors should start building positions gradually and focus on long-term gains.

The escalation of US-China trade tensions has made control over rare earth elements a key issue. China dominates the rare earth supply chain, impacting high-tech industries. American farmers, affected by soybean trade disruptions, are beginning to accept transactions in RMB. The trade war could trigger liquidity risks and black swan events, affecting the cryptocurrency market. While a resolution may be possible in the short term, failure to reach an agreement could pose greater risks to the crypto space. It is advised to monitor US-China developments closely and reduce leverage to mitigate risks.

I just saw some major news—Hong Kong’s tax authorities have officially clarified that buying and selling tokenized ETFs on licensed platforms will be completely exempt from stamp duty. It might not sound like a big deal at first, but think about it: stamp duty exemptions have always been a huge deal in traditional stock trading, and now they’re extending that to digital assets.
Even more impressive is this: Hong Kong plans to issue its first digital asset trading and custody licenses by early 2026. What does that mean? Starting next year, Hong Kong will fully integrate digital asset trading into its regulated financial system.
Surprisingly, Hong Kong dollar stablecoins are also a priority. Hong Kong’s Financial Secretary, Paul Chan, revealed that relevant legislation will be reviewed by the Legislative Council this year. In other words, a Hong Kong dollar version of USDT or USDC might not be far off.
All these moves clearly show that Hong Kong is positioning itself as a Web3 financial hub. The stamp duty exemption reduces trading costs, the licensing framework in 2026 will establish a compliant regulatory environment, and stablecoins are also on the agenda.

The 123 Rule is a simplified tool for identifying trend reversals, covering two scenarios: an uptrend turning into a downtrend and a downtrend turning into an uptrend. By observing three stages of price movement, investors can confirm reversal signals, set stop-loss and exit points, and enter positions precisely. When used in conjunction with the RSI indicator, this rule can improve trading effectiveness and help investors grasp trends in complex markets.
