What Is Wallet Authorization, and Why Should You Check and Revoke It Regularly?

In the Web3 world, connecting a wallet, using a DApp, and trading tokens are all common activities.

But many users may overlook one detail: when you click Confirm, what exactly are you authorizing?

An action that seems routine may allow a smart contract to access or use specific assets. If you don’t understand the scope of the authorization, or fail to check previously granted permissions over time, you could put your assets at risk.

1. What Is Wallet Authorization?

Simply put, wallet authorization means allow

Where Do DeFi’s High Yields Come From? Understand the Source of Returns First, Then Assess the Risks

In the Web3 world, DeFi is often associated with high yields.

Lending, liquidity mining, staking, and yield strategies offer users different ways to participate. But when a protocol offers a high annualized yield, what we really need to focus on is not just how large the number is, but: Where do these returns actually come from? And who bears the corresponding risks?

Understanding the source of returns is an important first step in deciding whether a DeFi project is worth researching further

Why Can a Trade Seem Profitable While the Final Account Returns Are Underwhelming?

In cryptocurrency trading, many people encounter this situation:

After buying, the price does rise, and the sale appears to show a profit, but when they check their account later, the actual return is not as high as expected.

The problem may not be with your market direction call. It may be that the profit you see is not necessarily the amount that ultimately remains in your account.

I. A Rising Price Does Not Mean All Costs Have Been Deducted

The actual outcome of a trade usually needs to account for:

Why Is Position Management Sometimes More Important Than Calling the Market Correctly?

Many traders devote a great deal of time to analyzing the market: when to buy, when to sell, and whether prices will rise or fall next.

But one question is often overlooked:

Even if you correctly predict the direction, an inappropriate position size can still lead to a poor outcome.

Trading results depend not only on whether your judgment is correct, but also on how much capital you commit, how much risk you take, and whether you can withstand the loss if you are wrong.

Do you think gold has bottomed?
I went a little long at 4037 yesterday, but it broke below VWAP and I took a loss 😭
My estimate is that it’ll trade in a range of 3950–4150 over the next month

The long position at 73,200 from this morning is already starting to show results. Next, if 75,000 breaks, we could see 76,000. Today, the long side will be the only one with an advantage over the short side. $BTC

DYOR: Why can you still make the wrong judgment after reviewing a lot of information?

In the cryptocurrency market, DYOR (Do Your Own Research) is a frequently mentioned term.

When someone recommends a project, you might read its white paper, browse social media, study the token price, or even refer to the opinions of well-known bloggers. But the problem is that getting more information does not necessarily mean you are closer to the truth.

Effective research is not about collecting as many opinions as possible, but about developing a method to verify information, identify risks, and revise

Stablecoins Are Not Cash: 4 Boundaries to Understand Before Using Them

Stablecoins are often seen as a bridge between traditional finance and the cryptocurrency market.

They can be used for trade settlement, on-chain transfers, DeFi applications, and cross-border value transfers. But many people overlook one issue:

A relatively stable price does not mean an asset is risk-free.

Before using stablecoins, there are four boundaries worth understanding.

1. A price peg does not mean you can always redeem at the target price

Stablecoins are usually pegged to an asset, such as the US dollar. But

What Opportunities Does DeFi Offer, and What Risks Does It Hide? Understanding the Mechanics Behind Yield

In the Web3 world, DeFi (decentralized finance) is often associated with concepts such as lending, liquidity mining, and yield farming.

Some people use DeFi to seek new financial opportunities, while others suffer losses chasing high returns.

So where does DeFi yield come from? Why can some protocols offer higher returns, and what risks are hidden behind those returns?

To understand DeFi, you cannot just look at the yield. You also need to understand how funds flow, how yield is genera

Why do so many people keep losing money in a range-bound market?
In crypto trading, many people prefer trending markets because they can go long when prices rise and go short when they fall, making the direction relatively easy to judge.
But what often causes many traders to keep losing money is a range-bound market.
Why?
First, range-bound markets are prone to fakeouts. BTC may just break above an important resistance level, making people think an uptrend is about to begin, only for the price to quickly fall back into its previous range. Traders who chase the rally get trapped, while those wh

XRP Holders vs. Ripple: Inside the Battle Over Price, Promises, and XRP Ledger
The XRP community timeline has turned hostile again. Over the past week, long-term holders have announced they are selling, a developer on the XRP Ledger has publicly criticized the ecosystem's direction, and an open letter to Ripple's leadership has divided the community. Executives and influential figures in the Ripple ecosystem are pushing back.
Here is what is driving this unexpected wave of negativity, what each side is saying, and where XRP's price stands now.

Why might a trading strategy that performs well in backtests fail in the real market?

A trading strategy may show strong historical returns, a high win rate, and a maximum drawdown within an acceptable range. Why, then, might the results be completely different once it is actually deployed in the market?

This does not necessarily mean backtesting is worthless. Rather, performance on historical data is not the same as returns that can be replicated in live trading.

To determine whether a strategy is truly effective, you need to understand several key issues behind the backtest results.

LTC market notes: Spot can enter with the first tranche; keep two tranches for adding

This recent pullback has been grinding. LTC fell from a high of 74.99 to around 50.5, and each rebound has failed to hold. In this market, it’s not about who can predict best, but who can control their hands and stick to discipline.
