Why Do Blockchain Transactions Fail? A Clear Guide to Troubleshooting, from Gas Fees to Smart Contract Restrictions

In the Web3 world, many people have encountered situations like these:

You click Confirm, but your wallet keeps showing Pending; sometimes a transaction suddenly changes to Failed; other times, it takes a long time to complete, leaving you unsure whether to keep waiting or try again.

These situations may look similar, but their underlying causes can be quite different.

Understanding why a transaction failed is more important than blindly increasing the Gas fee or repeatedly c

Why do some trading strategies perform well in range-bound markets but start losing consecutively as soon as the trend reverses?

Have you ever experienced this?

A strategy performs well over the past few months. Its backtest curve is smooth, and its win rate looks impressive.

But one day, the market starts to change.

Buy signals that used to work begin failing one after another, stop-losses become more frequent, and the account drawdown keeps growing.

You start questioning the indicators, adjusting parameters, or even considering replacing the strategy entirely.

But there’s one possibili

After seeing BTC rise, many traders expect a price pullback to get a better entry. But a retest is not always an opportunity; sometimes it may signal that a downtrend is starting again. The key is to determine whether support is holding and whether the overall market trend remains healthy.

First, assess the strength of the support level. If a price zone has seen rebounds multiple times in the past, it may indicate strong buying demand there. When the price returns to this zone, watch closely to see whether buyers step in again.

Second, watch for changes in trading volume. If volume gradually

SNDK and SK Hynix continue to rise, and the bullish view around 800 remains unchanged.

The reasoning behind being bullish on Sandisk around 800 was actually simple: after the previous correction, the price had gradually returned to a relatively normal range, so chasing the decline further offered poor risk-reward.

Over the past two days, South Korean markets have started buying storage-related stocks in force again, and SNDK and SK Hynix have continued to strengthen.

This rally is still ongoing. My previous view has not changed for now, with a near-term target still around 1000.

How to Build a Trading Cost Tracking Sheet and See Your True Profits?

Many traders review their trades every day, but may overlook one key question:

Your account looks profitable, but how much is left after deducting all costs?

Without complete trade records, you may know which trades made money, but not what is steadily eating into your profits.

Today, we’re sharing a trading cost tracking method you can put into practice right away.

1. Record every trade

We recommend creating an Excel spreadsheet that records at least the following:

* Trade date and trading pair
* Opening price and cl

Today marks the fourth anniversary of FTX filing for bankruptcy (November 11, 2022). The Anthropic stake liquidated by the bankruptcy estate back then would now be worth over $30 billion, based on the IPO price range Anthropic announced this week.
In 2021–2022, SBF’s FTX and Alameda spent about $500 million to acquire roughly an 8% stake in Anthropic, or 44.54 million shares. To repay debts in 2024, the bankruptcy estate sold the entire stake in two transactions at $30 per share: 29.47 million shares in March for $884 million, with an affiliate of Abu Dhabi sovereign wealth fund Mubadala alone

How Should You Manage Position Sizes? How Can You Use Scientific Position Sizing to Control Risk and Earn Steady Profits?

In cryptocurrency trading, many people study BTC’s price movements every day but rarely give serious thought to one question: even if you make the right call, how much capital should you put in?

In fact, many traders don’t lose because they misjudge the direction—they lose because of poor position management.

Suppose your trading account has 1000 USDT. If you put all your funds into every trade, a sudden market move could cause severe losses. Even if the market later mov

🚀 Anthropic’s IPO Could Reach a Massive $1.4 Trillion Valuation

Anthropic, the company behind the Claude AI ecosystem, is preparing for one of the biggest AI-related public offerings ever — and its potential valuation is putting the entire artificial-intelligence sector back in the spotlight.

According to its latest IPO filing, Anthropic plans to offer 825 million Class A shares at an expected price range of $70 to $78 per share. At the top of that range, the company could reach an estimated $1.404 trillion fully diluted valuation.

In the cryptocurrency market, many traders know some technical analysis methods yet continue to lose money repeatedly in choppy markets. The reason may not be that their technical skills are inadequate, but that they have failed to identify the current market condition.

The biggest difference between trending and choppy markets is how prices move.

First, in a choppy market, prices usually fluctuate repeatedly within a certain range, with resistance above and support below. If you follow a trend-trading approach—going long when you see prices rise and going short when you see them fall—you ca

With Layer 2, transactions are faster and fees are lower—but who exactly safeguards your assets?

In the Web3 world, Layer 2 is often seen as an important solution to blockchain congestion and high transaction fees.

It can help users complete transactions at lower cost and give more applications the opportunity to serve everyday users.

But there is an issue that is easy to overlook:

Does Layer 2’s improved transaction efficiency mean that asset security is protected to the same extent?

The answer is not that simple.

1. Layer 1 and Layer 2 have different roles

You can think of Layer 1 as

The daily bearish trend remains intact, with the Bollinger Bands opening downward and MACD showing expanding bearish momentum; overhead resistance is strong.

The 4-hour chart has remained below the Bollinger midline, with every rebound meeting resistance and pulling back—a pause during the downtrend.

The 1-hour KDJ is only edging up slightly, indicating a weak recovery after the decline. It lacks volume support and does not qualify as a trend reversal, so the rebound has limited upside.
