What Are Smart Contracts? How Do They Power Web3 Applications? Understanding Their Value and Risks, from How They Work to Real-World Applications

In the Web3 world, we often hear the term smart contract.

Many on-chain applications rely on smart contracts, including DeFi lending, decentralized exchanges, NFT trading, and DAO governance.

But what exactly is a smart contract? Can it really understand people's intentions like a traditional contract? Why can a vulnerability in the code cause serious asset losses?

Understanding these questions is an important step toward understanding Web3 infra

Why does rushing to break even after a trading loss often make things worse?

In cryptocurrency trading, a loss itself is not necessarily the most dangerous thing.

What is truly worth watching out for is how you react after a loss.

When an account suffers a drawdown, some traders immediately look for the next opportunity, hoping to make back their losses as quickly as possible. They may increase their position size, trade more frequently, or even abandon their original trading plan.

The result is often that they take on more unnecessary risk in an attempt to make up for their previous losse

Why might multiple seemingly diversified positions still carry the same risk?

Holding BTC and ETH, then adding tokens from several different sectors, may make your portfolio look diversified.

But if the market suddenly falls, you may find that these assets are all declining at nearly the same time.

This does not necessarily mean you chose the wrong project in every case. It points to an important issue:

Holding different assets does not mean you have truly diversified your risk.

1. Assets can be correlated

Tong Ge’s 11.12 BTC outlook
$BTC Short around 741-746, stop-loss at 751, targets 731-725-720.

First, a recap of yesterday: the 738-743 shorting range I gave bounced precisely to around 747 at its overnight high, then plunged all the way down, hitting a low of 73444. The levels I gave in advance played out again. Those who stayed on track caught another solid gain.

Now let’s look at today’s market.
The daily RSI has plunged to 29, and the KDJ is flattening at low levels. After a drop like this, a short-term bounce is perfectly normal. But remember: oversold only means it needs a breather; it

$PEPE It fell 15% in one day, hitting a low of 0.000004506, right at the edge of the long liquidation zone below.
It's now chopping around 0.00000458. The decline has slowed, but there's still no convincing rebound. Long liquidations are estimated to be concentrated around 0.0000045, with more below between 0.0000041 and 0.0000044.
Short positions are stacked in layers above, starting at 0.0000046. It won't be out of the woods until it can reclaim 0.0000048. For now, I'm watching to see if 0.0000045 holds; if it doesn't, I'll wait for lower levels.

#OpenAI第三季度营收升至100亿美元!
The $10 Billion Question: OpenAI’s Revenue Just Exploded So Why Is It Still Losing $10.9 Billion?
Stop and look at the numbers coming out of Silicon Valley this week. OpenAI just pulled in $10 billion in a single quarter (Q3 2026), jumping nearly 50% from Q2’s $6.7 billion and putting the company on a staggering $50 billion annualized revenue run rate.
By almost any historical standard, that makes OpenAI the fastest-scaling software business in history.
Yet right next to that $10 billion win sits an eye-watering number: $10.9 billion in quarterly operating losses, up fr

Why Are You More Likely to Lose Money After a Winning Streak?

In cryptocurrency trading, a streak of losses can make people cautious, but a streak of wins can sometimes make them let their guard down.

After several profitable trades in a row, many people may unconsciously start to feel:

“I’ve figured out how the market works.”

Then they start taking larger positions, widening their stop-losses, and gradually abandoning the trading plans they once followed strictly.

It is not until an unexpected drawdown wipes out a large portion of their accumulated profits that they realize the risks may

11.12 Gold

Gold fluctuated narrowly around 3992 today. After plunging to 3975 in early trading, it staged a slight rebound, but remained clearly under pressure overall. Overnight, gold prices fell decisively below the 4000 level, with the technical picture showing a classic bearish alignment: the 21-day, 50-day, and 100-day moving averages all gave way, while the MACD histogram’s green bars continued to narrow, signaling fading bullish momentum.

Bitcoin ETFs continue to see outflows. What signal is the market sending?

Recently, the Bitcoin market has shown a concerning trend: U.S. spot Bitcoin ETFs are experiencing a significant wave of net outflows. This is about more than price volatility; it also reflects some investors reassessing risk.

According to public data as of November 11, 2026, U.S. spot Bitcoin ETFs have seen cumulative net outflows of about $1.61 billion this month. On November 5, net outflows totaled about $430.2 million in a single day, followed by $411.9 million in net outflows on November 6. Outflows narrowed over
