What Is a Gas Fee? Why Does the Cost of the Same Transaction Keep Changing?

In the cryptocurrency market, some users may encounter this situation:

The transfer amount hasn’t changed, so why is the fee I pay today different from yesterday’s? Sometimes a simple transaction costs very little, while at other times it costs much more.

This involves an important concept: the gas fee.

Understanding gas fees can help you make sense of transaction costs and make more informed decisions when using wallets, DEXs, and other Web3 applications.

In cryptocurrency trading, there’s a very common phenomenon: many people are always quick to close their positions when they’re in profit, but once they’re at a loss, they’re reluctant to cut their losses.

Why does this happen?

First, when people are in profit, they’re afraid of losing the gains they’ve already made. Even a slight price pullback makes them worry the trend is reversing, so they sell early. As a result, trades that could have brought in much larger gains end up making only a little.

Second, when they’re at a loss, people are often reluctant to admit that their judgment may ha

How can a trading strategy perform well in historical backtests yet gradually fail in real markets?

A beautiful return curve does not necessarily mean a trading strategy is reliable.

In the cryptocurrency market, many traders use historical data to test entry signals, take-profit and stop-loss settings, and position parameters. But once a strategy is deployed in the market, its win rate may fall, drawdowns may widen, or it may even lose money over the long term.

What exactly goes wrong?

I. Historical data is not the same as future markets

Backtesting can only show how a strategy performed

Why Might a Strategy’s Returns Come from Just a Few Trades?

A strategy has high cumulative returns and a decent win rate.

But if you remove the few most profitable trades, the entire strategy goes from profitable to unprofitable. Would you still consider it to have a stable trading edge?

This question is more worth examining than returns alone.

1. First, look at where the returns actually come from

Suppose a strategy completes 100 trades in total and ends up with a net profit of 1000 dollars.

On the surface, the strategy is making money.

But a closer breakdown reveals:

#USAICStocksFallBroadly NVIDIA’s $430 Billion Shock: A CEO Investigation Meets a Wider AI Market Reckoning
The latest sell-off in American AI stocks is exposing a risk that goes beyond chip prices and quarterly earnings: the market is beginning to question how much confidence it should place in the companies, leaders and infrastructure behind the AI boom.

NVIDIA became the centre of that debate after reports involving CEO Jensen Huang triggered an independent board investigation and intensified scrutiny of the company's China-related chip business. But the broader decline cannot be explained

November 11 $ETH Market Update

Ethereum has fallen to around 2000. What should we do??

ETH has dropped sharply over the past few days, and market sentiment has turned broadly bearish, with many expecting prices to fall further.

But trading shouldn't be based solely on price movements; sentiment is also an important reference point.

On the daily chart, ETH previously saw a modest rebound at the first support level. The current price is in the second support zone I'm watching. I don't consider this a definitive bottom.

It's worth noting, though, that when bearish sentiment is widely shared

Why do some traders start increasing their position sizes after several consecutive wins, while after consecutive losses they tend to forget the trading rules they originally set?

There is an easily overlooked issue behind this: traders’ perception of risk changes with their recent gains and losses.

After consecutive wins, people tend to attribute their good fortune to their own ability.

As a result, positions that were originally cautious start getting larger, strict entry conditions begin to loosen, and they may even believe the next trade is worth taking on greater risk.

Setting a stop-loss does not mean you will definitely exit at the expected price.

Many traders believe that once they set a stop-loss in advance, their maximum loss is already fixed. But in real markets, the stop-loss trigger price may differ from the final execution price.

Why does this happen?

1. Market volatility: Prices may quickly move past the stop-loss level

When the market suddenly becomes highly volatile, prices may move past your stop-loss trigger price in a very short time. If the next available execution price is already worse, your actual loss may exceed your original plan.

Can 20 consecutive profitable trades prove that a trading strategy works?

Not necessarily.

If you don’t know the number of trades, the loss distribution, the risks taken, or whether the strategy has been repeatedly tuned, those 20 wins may not tell you much.

What really needs to be verified is not how much the strategy has made in the past, but whether it has an edge that can be repeated, explained, and tested.

I. Look at sample size, not just the win rate

Suppose two strategies both have a 70% win rate.

Strategy A has completed only 20 trades, while Strategy B has completed 1,000 trades

While AI stocks swing sharply, Anthropic's IPO has been fully subscribed almost as soon as it launched. The market may voice concerns that valuations are too high, but when it comes to a leading company like Claude, investors are still willing to pay.

The latest news is that underwriters are considering raising the offering price above the original $70–78 range, pushing the valuation to $1.5 trillion or even higher. However, this is still under discussion, and the final pricing has not been set.
