Connecting to a DApp Doesn’t Mean You’ve Completed an Action: What Exactly Is a Web3 Wallet Authorizing?

In the Web3 world, a wallet is not only used to receive and send digital assets, but is also an important gateway for users to interact with decentralized applications (DApps).

You may have connected to DeFi platforms, NFT marketplaces, or on-chain games. Clicking “Connect Wallet” may seem like a small step, but connecting, signing, and authorizing transactions are actually different actions.

I. Can an app take your assets just because you connect your wallet?

Usually, simply connecting

75411 top signal—I wrote it a day in advance! Both BTC short targets fully hit
This morning’s strategy was clear: short at 75500–75800, stop-loss at 76200, targets at 74200–73800
The market gave its answer: the high of 75411 met precise resistance; prices then drifted steadily lower, fully hitting the targets.
The entry was accurate down to the last digit, and the direction was right for the entire move. That’s what “make the call first, then wait for the price to come to you” means.#BTC #美国10月CPI全面超预期

On November 10, Musk publicly conceded defeat on X—to a rival's model, no less. A user asked him: How does xAI's upcoming Grok 4.8 compare with Anthropic's Claude Opus 5.5? He replied bluntly: "Not as good. Opus 5.5 is a masterpiece." This reply has been viewed over 1 million times.
He then added: Grok 5 should surpass Opus 5.5, "possibly within 2 to 3 months," and keep accelerating after that. Anthropic released Opus 5.5 on September 22.
That same day, he also revealed that xAI had scrapped JAX and SGLang and rewritten its entire reinforcement learning and inference systems from scratch in C/

What Is Price-Volume Divergence? Why Might Trading Volume Gradually Decline While Prices Keep Setting New Highs?

In the cryptocurrency market, a phenomenon that warrants caution sometimes occurs: BTC prices keep setting new highs, while trading volume continues to decline. On the surface, the market still looks strong, but in reality, signs of weakening upward momentum may have emerged. This phenomenon is called price-volume divergence.

First, what is price-volume divergence? Simply put, it is when price movements and changes in trading volume are inconsistent. For example, prices continue t

What Is Strategy Overfitting? Why Should We Be More Cautious When a Historical Return Curve Looks Better?

In cryptocurrency trading, some strategies have their parameters repeatedly adjusted until their historical return curves look very smooth and their win rates are high. But once they enter the real market, their performance drops significantly. This may be strategy overfitting: the strategy has adapted too closely to specific patterns in historical data without learning to handle future market changes.

First, how does overfitting occur?

Common causes include repeatedly adjusting paramet

What Is Market Liquidity? Why Doesn’t High Trading Volume Necessarily Mean Large Orders Can Be Filled Smoothly?

In crypto trading, trading volume is often used to gauge market activity, but high volume doesn’t mean there are necessarily enough buy and sell orders available right now. What really affects whether orders can be filled smoothly is the depth of orders at different price levels, the bid-ask spread, and the market’s ability to absorb buying and selling pressure as orders are executed.

First, what is market liquidity?

Market liquidity refers to how quickly an asset can be bought or

What Is a Trading Plan? How Can You Combine Entry, Stop-Loss, Take-Profit, and Position Management into an Executable Set of Rules?

In cryptocurrency trading, many people analyze the market every day but have no clear trading plan. They chase prices when they rise, then change their stop-loss on the fly when they incur losses, ultimately letting emotions drive their trading decisions. A trading plan’s value lies in setting out in advance the conditions for entering a trade, how to control risk, and when to exit.

First, what does a trading plan include?

A complete trading plan typically incl

Why Can Long Positions Still Lose Money When the Funding Rate Is Positive?

In crypto perpetual futures trading, many people see a positive funding rate and assume the market is bullish, so holding a long position should make it easier to profit. But the funding rate reflects the payment mechanism between longs and shorts in the futures market; it does not guarantee that prices will rise.

First, a positive funding rate does not mean prices will definitely rise. A positive funding rate usually means longs pay funding fees to shorts, but prices can still be affected by spot selling pressure, ma

Why Can You Still Lose Money Even When AI Predicts an 80% Chance of BTC Rising?

More and more traders are starting to use AI to analyze cryptocurrency markets. Some models may even estimate an 80% chance that BTC will rise and a 20% chance that it will fall. But one easily overlooked point is that a high probability forecast does not mean the trade is guaranteed to make money.

First, an 80% probability forecast does not mean the price will definitely rise. It usually means that, under similar historical conditions, the model considers an upward move more likely. If the model has not been val

What is market impact cost? Why might a large order continuously drive up the purchase cost or push down the selling price as it is executed?

In cryptocurrency trading, a large order cannot necessarily be filled at the latest price shown on screen. When an order exceeds the quantity available at the current price level, it must continue to match with higher sell prices or lower buy prices, resulting in market impact cost. This is an important component of the actual execution cost and deserves particular attention from large traders.

First, what is market impact cost?

Market impact cost is

What Is an Iceberg Order? How Can It Hide Part of an Order’s Size and Reduce the Visible Market Impact of Large Trades?

In cryptocurrency trading, placing a very large order directly on the order book may allow other market participants to infer the trader’s intentions, affecting prices and execution conditions. Iceberg orders reduce how much of the full order is exposed at once by displaying only part of the order size and replenishing the displayed quantity after it is filled.

First, how do iceberg orders work?

Suppose you plan to buy 100 BTC but display only 10 BTC at a time. Once the di
