Recently, I have been relatively free in smart contract development at work, and I want to try to consistently publish K-line technical analysis and quick reports on the cryptocurrency market. I will also share more on-chain information afterwards.

These past few days have been busy, not posting many updates. Heading to Asia this weekend! Gotta get out of Europe for a month, it's too cold here. Can't wait to get to Hong Kong!

Next, I'll continue analyzing $BTC and the latest web3 news!

Transferring ETH from a ledger cold wallet to Binance, thought I'd convert to USDC and buy more when it drops, but it fell before I could sell 😅

💥 $BTC 1 January 5th, just over an hour before the close, broke 94K!!

On January 2nd, approximately 470 million USD flowed into the US spot ETF in a single day, the largest since November last year! At the same time, the sudden changes in Venezuela's political situation have amplified the market's expectations for supply tightening and safe haven, resulting in $BTC soaring close to 94K USD, successfully stabilizing above the 50-day moving average.

💎 92K has always been a key level between the previous high volatility zone and higher targets (like 100K), which has finally been broken today.

👀 Short-term focus

➡️ Macroeconomics and events: The Trump administration's arrest of Maduro has increased risk appetite, but the subsequent evolution of oil prices and geopolitical situations remains uncertain. There are rumors that Venezuela holds “shadow” Bitcoin reserves (meaning privately held Bitcoin that is not publicly disclosed or officially confirmed), which should be treated with caution. - Bloomberg

➡️ Technical levels and risks: The important support after the breakout is between 90-92k, while the upper resistance area is 95k-100k. If the funding rate continues to rise, be cautious of high-level consolidation or even a pullback.

🚀 #zcash （$ZEC ）'s performance in 2025 clearly deviated from the mainstream market. Among cryptocurrency assets with a market capitalization of no less than 1 billion USD, ZEC's increase this year exceeded 800%!\n\n💰 ZEC price rose from about 60 USD at the beginning of the year to about 506 USD. During the same period, $BTC was approximately -6.2%, and $ETH was about -10%. In terms of scale and liquidity, Zcash had a market capitalization of about 8.3 billion USD at the time of writing, with a 24-hour trading volume exceeding 800 million USD.\n\nAdditionally, Cypherpunk Technologies disclosed an increase of 56,418 ZEC on December 30, 2025, with an investment of approximately 29 million USD.\n\nDo you think the return of blockchain privacy is a long-term trend or just a year-end phase trading?🤔\n\nSource: The Defiant

【January 3rd $BTC Data Analysis】

➡️ On-chain data:

In the past 24 hours, Bitcoin futures open interest surged by 2.16% to $130 billion - CryptoNews

👉🏼 Short-term and leveraged funds are increasing, which can drive prices up rather than being led by spot market increases.

➡️ ETF:

Bitcoin spot ETF saw a net outflow of about $244 million last week - bitcoinist, indicating that institutional spot funds have not increased their positions during the price surge.

👉🏼 The market is more likely to move sideways or fluctuate before key resistance levels.

➡️ Whale movements:

After excluding the impact of internal wallet consolidation at exchanges, real whale addresses holding ≥1000 BTC have decreased, and medium-sized holding addresses are similarly weak - CryptoQuant analysts

👉🏼 Reflects overall caution from large funds.

#BTC走势分析

📈 The new year has begun, and the cryptocurrency market is so active that I was still awake at 2 AM!

While the price of Bitcoin reached 90K, mainstream altcoins like $ETH , $SOL , and $XRP also saw a rise of about 4%. The market capitalization share of Bitcoin has slightly declined, reflecting that some funds are beginning to shift from Bitcoin to higher volatility assets.

Meme coins like Dogecoin and PEPE showed a significant increase at the start of the new year, with a short-term rise of 20–25%.

👉🏼 Generally speaking, when market sentiment strengthens, funds often shift from Bitcoin to altcoins and meme coins in pursuit of faster and larger gains. This situation indicates that risk appetite is on the rise.

#加密市场观察

✨ In the past 48 hours, the price of $BTC has generally been rising slowly, but with fluctuations in between. After rebounding from around 88K, it broke through and stood above 90K with a significant increase in trading volume! After approaching 90.7K multiple times, it has turned to consolidate horizontally above 90K.

👌 This indicates that the upward trend is still continuing, as the price has remained above the recent MA for most of the time. At the same time, buying power still dominates, but it is approaching a slightly overheated state, making it easier for a pullback to occur after a rise.

👀 Under the current structure, the support levels to focus on for BTC below are 90K, 89K, and 88K, while the short-term resistance above is at 90.7K. If it breaks through with increased volume, it is expected to test 92.5K and continue to rise.

#BTC走势分析

$BTC The overall trend on the hourly chart remains bullish, but the price is closely touching the upper Bollinger Band, and the RSI is obviously overheated, making it difficult for a direct surge in the short term.

Currently, it seems to be a slight pullback to digest the gains. Let's see if it will break below around 89k; if it doesn't, the structure still leans strong.

💥The highest daily trading volume of the year #太坊链 10 at the end of the year, but the prices have not kept up.

At the end of December, on-chain transactions surged to an abnormal level of $ETH , with over 2.1 million transactions in a single day, according to Etherscan, marking a new high in nearly 10 years!

In Q4 2025, new smart contract deployments exceeded 8.7 million, and the number of staked ETH in the queue at the end of the year rose to 890,000 ETH.

However, some authors from CryptoQuant believe that this spike in trading could be a signal of growth or a “panic/selling pressure” signal during a downturn.

🍺 Last day of 2025, the weather is great! It's not important how much you earn, keep learning, and don't lose your spirit. Wishing everyone a steady progress in the new year!

$BTC 12/30 Daily line UTC 23:20 half an hour until closing 👇👇

In the past two days, $BTC rose sharply and then fell back, oscillating near the 7-day and 25-day moving averages on the daily chart. On the hourly chart, the EMA 7/25/99 has formed a golden cross, MACD has turned positive from negative, RSI is about 58, and short-term bulls have a slight advantage, but the resistance around 88.8K has not been effectively broken => short-term is highly likely to oscillate in the 86k-90k range.

👀 Short-term focus:

- Current funding rate is about 0.0057%, contract open interest has decreased by 1.95% in the last 24 hours, long-short ratio is about 0.97, net outflow from the exchange is 6066 BTC, and the spot ETF has seen a cumulative net inflow of about 61,100 BTC in the last ten days => long and short forces are relatively balanced, sentiment is cautious, and capital outflow provides slight support to the price.

- On the hourly level, pay attention to the 88.8K USD level, if this position is held, there is hope to challenge 90K. If the breakout fails, it may retest the support near 87K USD.

Note: The cryptocurrency market is highly volatile, predictions are not guaranteed to be accurate. The above analysis is for reference only and does not constitute investment advice.

🔥 Even with fluctuations in December, Strategy (#MSTR ) bought another 1,229 units of $BTC (approximately 108.8 million USD) at the end of the year!!

During the period from 2025/12/22 to 12/28, Strategy, led by Michael Saylor, continued to increase its holdings amid market fluctuations:

- Total holdings: 672,497 BTC
- Total cost: 50.44 billion USD
- Average cost: approximately 74,997 USD/BTC

💰 Where does the investment money come from?

It comes from gradually selling its own stock (MSTR) in the market to finance and quickly converting the funds into BTC. The goal is to turn equity financing into "digital gold."

In 2025, BTC yield reached 23.2%, meaning "the amount of BTC corresponding to each share is increasing," which is not entirely equivalent to the rise and fall of BTC prices.

🐳 Generally, when $BTC drops, retail investors tend to panic and sell, but whales tend to act differently: they buy on dips!

So recently, when prices have retraced, some participants with larger capital have started to gradually increase their positions, indicating that there are buyers willing to take over at this level, making it less likely to continue dropping significantly. Additionally, the high-risk positions that were under pressure earlier have seen reduced losses due to the rebound, which also diminishes the likelihood of a sharp decline in the short term. Overall, the short-term outlook is a bit more stable than before.

💥 Year-end $BTC Rebound Behind: Whales Are Buying, Liquidation Risk Is Decreasing! 👇🏼

☕️ Latest News:

➡️ On December 29, signs show that whales have started to withdraw and hoard coins: two newly created whale addresses withdrew a total of 1,600 BTC from Binance, worth about $144 million. - mexc

➡️ On-chain large holders' balances are increasing, indicating that whale funds are accumulating at low levels. Additionally, on-chain data suggests that some whales' massive long positions have reduced losses due to the rebound (for example, a certain "insider whale" saw losses decrease from several hundred million dollars to about $24.86 million when BTC > 90k, in USD terms). - mexc

📈 $BTC confirmed a rapid rebound after hitting a stage low around 87.4K on an hourly level on 12/29, reaching a high of 90K, currently back above the short-term moving averages, with MACD expanding and short-term momentum leaning bullish, but RSI has entered the overbought zone, indicating a need for a pullback.

👀 The short-term (1–3 days) structure is showing strong high-level fluctuations, with support levels to watch at 88,600 / 87,400 / 86,000, and resistance above in the 90,000-93,500 range; proceed with caution when chasing highs, as sharp declines are more easily absorbed.

【DeFi Hacking Review】💸 An oracle upgrade turned 8 decimal places into a $2.7 million withdrawal machine!!

📌 Event Summary:

- Victim: #aevo (the old version of DeFi options vault of #RibbonFinance ).
- Time: December 12, 2025.
- Loss Amount: Approximately $2.7 million.
- Core Reason: Caused by an oracle upgrade maintenance on December 6 by the officials.

⚡️ I have tried to explain this attack process in the simplest terms; if you don't have time, you can just look at the pictures! 👇🏼

1️⃣ Vulnerability Introduction:

This official upgrade not only mistakenly exposed key management permissions (transferOwnership and setImplementation were left unprotected) but also caused a mismatch in decimal precision between the old and new systems (18 vs 8).

2️⃣ Attack Preparation:

The hacker exploited the above precision vulnerability to create a special options product. This product had extremely low costs but appeared to be worth a fortune under the system's erroneous calculations.

3️⃣ Seizing Control:

The attacker used a "scapegoat" wallet (which met the tx.origin permission check vulnerability) to initiate transactions, successfully taking control of the oracle proxy admin.

4️⃣ Cycle Attack: Repeat this process

- Price Manipulation: The hacker obtained admin privileges and told the system: "Now the price of this asset is infinity".

- Withdrawal: The hacker took their low-cost "fake money" (malicious options) to cash out. The system paid the hacker real WETH and USDC at the erroneous high price.

- Cover-Up: After withdrawing, immediately change the price back, pretending nothing happened.

5️⃣ Money Laundering and Escape:

Dispersed the stolen money, washed it through Tornado Cash, and disappeared on-chain.

🌟 Summary: Therefore, every upgrade of #智能合约 must be extremely careful! Not a single mistake can be made! ❌

Today the market is volatile, and there is no doubt that it is because on the 26th, options worth $27.14 billion with expiration dates $BTC and $ETH will be due. This is considered the highest amount of options expiration in history!

On the hourly chart around 8 AM UTC, $BTC showed a strong rebound after a dip and washout, currently in a high pullback and consolidation phase after the surge. The bullish structure is still in place, but the short-term momentum has slowed down, and the key point is whether 88100-87800 can hold.

💸 During the Christmas period, multiple users' cold wallets with the #TrustWallet were stolen, resulting in losses of millions of dollars!!

It is suspected to be related to the browser extension update released on December 24. This update may have encountered an attack, leaking sensitive data through hidden code when users imported their mnemonic phrases, subsequently leading to the wallets being cleared. - Coin Academy X account

Are you using Ledger, Trust Wallet, or another wallet??

$PUMP The price has recently dropped significantly, coinciding with the escalation of legal disputes involving #pumpfun .

Although the project still has considerable revenue and continues to buy back tokens, the PUMP price has fallen more than 50% from the ICO.

U.S. law firms have accused the platform of harassment and threats against individuals, with much of the related content coming from user-created memecoins rather than direct actions by the official team. Currently, there is no evidence to suggest that the Pump.fun team is involved. - The Defiant

The market generally does not make such distinctions; in open issuance platforms, when ecological projects face issues, it is also difficult for the platform to avoid being implicated.

🎄🎄 Merry Christmas! I hope you earn a little whether it's empty or plenty! 🎄🎄💸
