Some time ago, I saw some discussions about health insurance on Twitter, and recently I've been considering related matters. Let's get straight to the conclusion (only considering the medical part, excluding critical illness insurance, life insurance, and other slightly financial types of insurance, after all, it's unlikely to outperform DeFi returns):
1. Buy for parents (elderly) Directly buy million-dollar health insurance If there is no employee medical insurance, then resident medical insurance + million-dollar health insurance. The resident medical insurance part is 400 yuan/year, and million-dollar health insurance usually costs 2000 yuan - 3000+ yuan/year, the older you are, the more expensive it gets. Function: Covers medications outside of medical insurance, such as some special drugs, imported drugs, targeted drugs, and some additional medical services, such as green channels for medical treatment.
2. Buy for young and middle-aged people For those with employee medical insurance, pay as an employee; for those without, paying for flexible employment is equivalent to employee medical insurance, flexible employment costs about 4500 yuan/year. Taking 30 years old as an example, if you pay for 30 years and retire at 60, you won't have to pay anymore, but you can still enjoy employee medical insurance benefits, totaling about 130,000 yuan. At this age, I personally think the body is still relatively healthy. Although buying million-dollar health insurance is cheap, the usual deductible is 10,000+ and needs to be reimbursed by national medical insurance before it continues to be reimbursed, so you need at least tens of thousands in treatment costs to use it. For young and middle-aged people, it's a bit useless; it's better to focus more on health, and if there are issues, go for a check-up, anyway, the outpatient quota every year is wasted if not used. Wait until you get a bit older to buy million-dollar health insurance. However, if you find it troublesome, you can buy it directly, just a few hundred yuan each year, flexible employment + million-dollar health insurance can be bought until 80 years old, totaling about 250,000 yuan.
This means that as long as you invest less than 10,000 yuan each year from 30 to 60 years old before retirement, you will be secure for life; the line of disease won't have anything to do with you. You just need to work hard to live to 80.
Positioning: Filecoin is more like a "decentralized cloud storage," emphasizing versatility; Arweave is a "pay once, store forever" on-chain archival system; Walrus focuses on large-scale data storage at the Blob/DA level, designed natively for Web3 and AI.
Architecture: Filecoin and Arweave are both independent L1s; Walrus is natively built on Sui, leaning more toward a modular data layer.
Cost and Performance Trade-offs: Filecoin has a more complex cost and mechanism; Arweave has high initial cost but offers permanence; Walrus achieves lower cost and higher throughput through low redundancy design.
Programmability: Filecoin is medium; Arweave is relatively weak; Walrus's data is object-level and directly callable by contracts, offering stronger composability.
On the track of 'privacy + institutions + compliant finance,' many projects are often grouped together, but the actual work they do is quite different. Let's compare the recent topics of discussion,
compared with two other projects in the privacy space.
First, look at @zama — its core is FHE-based privacy computing, leaning more toward foundational cryptography and general privacy computing capabilities, essentially focusing on 'how to securely compute data.' Whereas
focuses more on the layer closer to the outcome: how securities, trading, and compliant financial applications can truly be implemented on-chain, directly addressing the financial market structure itself.
Upon investigation, Powell lost his ideals and convictions, deviated from his original aspirations and mission, violated political discipline by selectively implementing the Federal Reserve's quantitative easing policy, causing irreparable massive losses to the President and the general public of investors, showing disloyalty and dishonesty toward the President, resisting Federal review, and failing to truthfully explain issues during questioning; violated integrity discipline by using his position to help his relatives secure engineering projects from loan clients; neglected family values, failing to properly manage and educate his relatives; engaged in decadent lifestyle, having improper relationships with multiple women and frequently visiting entertainment venues; violated national laws and regulations by using his position to assist certain enterprises in obtaining loans, jointly accepting large amounts of property with others,涉嫌 bribery crimes.
Powell violated the President's political, integrity, and lifestyle disciplines, constituting serious official misconduct and suspected criminal acts, and did not refrain or desist during the President's second term, with severe nature and extremely negative impact, thus warranting strict handling.
The first project to break below issuance price in MetaDAO has emerged. I've been closely tracking the latest ICO round, and today the TGE was officially drawn. Here's a summary of my observations over the past two days.
The ICO project ranger_finance is a Perp Dex aggregator on the Solana blockchain, also one of the recently popular sectors. ICO Date: January 6, 2026, 16:00 UTC - January 10, 2026, 16:00 UTC Target Raise: $6,000,000 (hard cap) ICO Token Pool: 10,000,000 RNGR Percentage of Total Supply: Approximately 39.02% (Total Supply: 25,625,000 RNGR) Corresponding FDV: $15,375,000 ICO Tokens: 100% unlocked at TGE
The final raised amount reached approximately $86M, but the team decided to increase the target raise to $8M, corresponding to an FDV of $20.5M. The previously mentioned buy wall mechanism was not implemented, and the excess funds were refunded to investors. TGE price was $0.83 within 5 minutes, allowing for a small profit if claimed and sold immediately. However, as of the time of writing, the token price has dropped to $0.66, indicating it has broken below issuance price.
Potential reasons for the price drop: 1. A large portion of the token supply was released during the ICO. Although the team and investor allocations remain locked, a 40% circulating supply is still substantial. 2. After heyperliquid opened up new possibilities in the Perp Dex space, follow-up projects such as Aster and Lighter have emerged. Ranger, by comparison, has received relatively less attention. Moreover, Solana already hosts established Perp DEXs like Jupiter, which occupy a significant market share.
Binance $USD1 practical guide: no need to rush, no de-peg risk, annualized returns up to 25% - full process
Before Binance launched the USD1 20% promotion, USD1 had a normal premium of -0.1%. After the promotion started, it turned into a positive premium. The price volatility of USD1 directly impacts returns. Besides rushing to participate before other users, borrowing USD1 can also help avoid the risk of USD1 price fluctuations, allowing you to stay in the promotion until the final day and capture the full cycle. Since borrowing is required anyway, you might as well leverage existing DeFi protocols to increase capital efficiency and stack returns for higher yields.
Core logic: 1. Pendle's PT-USDai currently has an APY of 7.28%, which can be used as collateral on Morpho to borrow USDT at 1.1% APY, creating an arbitrage opportunity.
Binance $USD1 Practical Operation: No Need to Rush, No Risk of Depegging, Annual Yield Up to 25% Throughout the Process
Before Binance launched the USD1 20% APY campaign, USD1 had a常态化 premium of -0.1%. After the campaign started, it turned into a positive premium. The impact of USD1 price fluctuations on returns is obvious. Besides rushing before other users before the campaign ends, you can also borrow USD1 to avoid the risk of USD1 price volatility, allowing you to stay in the campaign until the final day and capture the full cycle. Since borrowing is involved, you might as well leverage existing DeFi protocols to improve capital efficiency and stack layers for higher returns.
Core Logic: 1. Pendle's PT-USDai currently offers 7.28% APY. It can be used as collateral on Morpho to borrow USDT at 1.1% APY, creating a layer of arbitrage opportunity. 2. Aster's asUSDF currently offers 5.2% APY. It can be used as collateral on Lista to borrow USD1 at 2.9% APY, providing a second layer of arbitrage. 3. Binance USD1 20% APY campaign.
Operation Flow: 1. Buy PT-USDai on @pendle_fi - Arbitrum chain. 2. Deposit PT-USDai on @Morpho to borrow 90% of principal in USDT. 3. Transfer the Arbitrum USDT to Binance and withdraw to BSC chain. 4. Use DEX to buy USDF with USDT, then deposit on @Aster_DEX to receive asUSDF. 5. Deposit asUSDF on @lista_dao to borrow 90% of principal in USD1. 6. Deposit the borrowed USD1 into Binance's 20% APY savings product.
Notes: 1. On Morpho, the LLTV is 91.5%, so borrowing 90% carries relatively low liquidation risk; same applies to Lista with the same LLTV. 2. Redeeming USDF back to USDT incurs a 0.1% fee. However, buying USDF with USDT on DEX is likely to result in a purchase price higher than 0.1% premium, effectively subsidizing the fee. $

In 2020, I naively thought: "Once $ETH transfers to POS and we enter the ETH 2.0 era, gas will surely become as cheap as air, right?" As a result, the term ETH 2.0 was replaced by Beacon Chain, and during DeFi Summer, gas could soar to hundreds of dollars per transaction, making me feel completely overwhelmed. Now that the Fusaka upgrade has finished, I just tried a simple transaction, and the gas was really low enough to be ignored. I suddenly remembered that naive version of myself.
Amid the joint crackdown by 13 departments, why are there still countless 'guiding people to claim airdrops' videos on Douyin and Xiaohongshu? Is it a blue ocean of traffic, or a red ocean of exploitation?
Recently, similar videos promoting 'guiding people to claim airdrops' have frequently appeared on domestic short video platforms. The content and style of these videos are completely different from my previous understanding of airdrop claiming. When something seems unusual, there's usually a hidden reason. The frequent appearance of such content indicates this phenomenon has existed for some time. On one hand, 13 departments are jointly cracking down on virtual currency speculation; on the other hand, platforms like Xiaohongshu, Douyin, and Video号 are filled with 'guiding people to claim airdrops for wealth.' This contradictory 'open defiance' is not a blue ocean of traffic, but rather a 'domestic pig slaughter scheme' targeting newcomers.
1️⃣ Paid Groups
This is relatively straightforward: high entrance fees are charged, and you must become a 'sacrificial sheep' before you can 'claim the airdrop.' An entrance fee of nearly 6,000 RMB is required. Given the current state of airdrop opportunities, it's difficult for ordinary people to break even by operating dozens of accounts, let alone recover the 6,000 RMB fee. Moreover, after paying, what you receive is most likely free tutorials written by other airdrop instructors—content that's freely available elsewhere.
2️⃣ High-Priced 'Shovels'
You think 5,988 RMB is too expensive? 'Free guidance, profit-sharing once you earn' sounds reasonable, but here comes the second trap. Since it's free, you're required to use their tools. Purchasing these tools allows you to become their partner and join the group, gaining access to shared airdrop information. X accounts, Discord, fingerprint browsers, IP addresses—everything is priced N times higher than market rates. The cost of a single set of accounts easily exceeds 4,000 RMB. They don't profit from airdrops; they make money by selling you overpriced 'shovels.'
3️⃣ Agency Airdrop Services
After buying accounts, you still need to screen projects. Too many accounts, complicated operations, high learning curve—but the myth of quick wealth from airdrops is too tempting to ignore. No worries, they've thought of everything. Just pay an additional service fee on top of the high account cost, and a professional team will handle everything for you. This is the biggest black box. The information asymmetry ensures participants are at a disadvantage. Once your capital is gone, they can easily shift blame with excuses like 'the project team detected sybil attacks' or 'token launch delayed.' Your funds vanish with no recourse. To be blunt, this is a scheme designed solely for harvesting money—expecting to recover your investment is pure fantasy.

Attempt to Understand Crypto Assets from Duan Yongping's Perspective - AAVE
Recently, the video of Duan Yongping interviewed by Xueqiu has become quite popular. His value investment philosophy, which originated from the same school as Buffett, is recognized by many crypto guys who have achieved great results. Coincidentally, the market atmosphere has been low lately, and voices about the bear market are rising. Only when the tide goes out do we know who has been swimming naked. This might be the time for the market to test which assets are truly good. We can use Duan's investment philosophy to try to understand which crypto assets have characteristics that align with value investing. The first asset to analyze is one of the cornerstones of DeFi - AAVE. Let's dive in.
