Hot wallet or cold wallet? What really matters is not choosing one over the other, but how you manage risk.

When many people discuss digital asset security, the first thing they think of is transferring assets to a cold wallet.

But that does not mean a cold wallet can solve every security problem, or that a hot wallet is necessarily unsafe.

Hot wallets are usually connected to the internet and convenient to use, making them suitable for everyday interactions and small transactions; cold wallets minimize contact between private keys and online environments, making them better suited for hold

What is triangular arbitrage? How can you use price relationships among three trading pairs to find opportunities, and why can trading fees turn theoretical profits into losses?

In crypto markets, temporary pricing discrepancies sometimes arise among different trading pairs on the same exchange. Triangular arbitrage takes advantage of these discrepancies by completing three consecutive trades to exchange assets, aiming to end up with more of the starting asset. But seeing a price gap does not necessarily mean a trade will be profitable.

First, what is triangular arbitrage?

What Is Cross-Exchange Arbitrage? Why Can Price Differences Between Two Platforms Be Offset by Transfer Times and the Cost of Tying Up Capital?

The same crypto asset may be quoted at different prices on different exchanges. Traders can try to buy on the platform with the lower price and sell on the one with the higher price to capture the spread. But what seems like a simple trade is also affected by fees, transfer speed, and market volatility.

Cross-exchange arbitrage involves trading on price differences for the same asset across different platform

Oracle Could Lead the Next AI Applications Rally
The US technology market is facing heavy selling pressure, but I believe the AI revolution is far from over. Instead, investors are changing their priorities. Previously, the focus was on AI chips, servers, and data centers. Now investors want to see real revenue, sustainable profits, and measurable returns from AI investments.

My main focus is Oracle (ORCL) because its cloud infrastructure, enterprise software, and database technology could position it strongly in the next stage of AI adoption.

A loud bang has sounded on Wall Street, where a real-life "Battle Royale" is unfolding among hedge funds.
First, take a look at these alarming figures:
**Walleye Capital, a $17 billion fund, couldn't hold on.** The multi-strategy hedge fund has cut its core long-short equity team, returned capital to investors, and begun restructuring. It lost 5.9% in October alone, its worst performance since March 2020—remember, that was the month of U.S. stock market circuit breakers.
**Even more striking are the figures disclosed by Goldman Sachs: Hedge funds net sold about $20 billion in tech stocks over

The US stock market is facing serious selling pressure, with the Nasdaq dropping more than 5% on Thursday.

This could be a short-term deleveraging event, but it also raises concerns about stretched valuations and heavy expectations surrounding AI companies.

My focus is on the semiconductor and AI infrastructure sectors. Despite the current volatility, these industries remain important for long-term technological growth.

However, I would rather wait for market stabilization and better entry opportunities than rush into falling

What Is Fibonacci Retracement? Why Do Traders Focus on the 38.2%, 50%, and 61.8% Price Retracement Levels?

In crypto trading, prices often pull back after rising and may also rebound after falling. Fibonacci retracement is a common technical analysis tool that traders use to identify potential support and resistance zones based on specific ratios. However, these levels are not guaranteed reversal points, nor do they guarantee profitable trades.

First, what is Fibonacci retracement?

It calculates different retracement levels between the start and end points of a clear price move, helping tra

Overview and Macro Structure
Bitcoin is currently exhibiting a pronounced bearish structure on the intraday charts. Following a rejection near the 80,949.2 local high, the asset has undergone a significant distribution phase, culminating in a sharp impulsive move to the downside. The current spot price sits at 76,156.0, reflecting a 5.42% daily decline. This price action invalidates the prior bullish consolidation and shifts the immediate market bias firmly to the downside.

🔐 Digital Asset Security Checklist: What Information Should You Verify Before Using It?

In previous posts, we discussed what restrictions digital assets may be subject to, how to verify information through blockchain explorers, and how to assess the practical impact of blacklists, whitelists, paused transfers, and upgradeable contracts.

But after understanding these mechanisms, there is a more practical question:

When you are preparing to buy, receive, transfer, or approve a digital asset, what exactly should you check first?

Many risks do not arise because users know nothing about techno

#Gate推出行业首个资金安全证明
Proof of Reserves Was Only Part of the Security Question. Now Comes Proof of Storage.

For years, one of the biggest questions users have asked centralized exchanges has been simple: are customer assets fully backed?

Proof of Reserves was an important step toward answering that question. But there is another issue that deserves just as much attention: even when an exchange holds enough assets, how are those assets actually stored, and what happens if its online wallets are compromised?

How Can AI Agents and Web3 Integrate? The Real Opportunity Lies in Connecting Collaboration Across the Digital World
AI is moving from content generation to task execution, while Web3 continues to explore digital identity, asset management, and open collaboration. What deserves attention in combining the two is not simply connecting AI to a blockchain, but how to enable agents to complete real tasks more securely and efficiently across different platforms.
First, digital identity is the foundation for collaboration. AI agents need to know whom they represent, what permissions they have, and wh
