What Is Class Imbalance? Why Can Cryptocurrency Prediction Models Seem Accurate Yet Have No Trading Value?
In cryptocurrency quantitative trading, a model’s accuracy can easily be misleading. If most periods in the test data do not feature a strong rally as defined, a model that always predicts “no rally” may still achieve high accuracy, yet fail to identify genuine trading opportunities. This is the problem of class imbalance.
First, what is class imbalance?
Class imbalance occurs when the numbers of samples in different classes in a dataset vary greatly. For example, only 100 out of 1,000 sa

“Dark clouds press upon the city, threatening to crush it”
The market suddenly plunged, with prices weakening rapidly and many holders on edge.
$BTC
A sharp drop can most easily undermine confidence; panic selling often means selling at the bottom.
$ETH
Markets move in cycles. During a sharp drop, avoid panicking blindly. Figure out whether it is a short-term pullback or a trend reversal, and plan your next steps.
Find like-minded people who stay calm, assess the situation together, and wait for opportunities. #BTC争夺8万美元关口

The same coin is listed at 100U on Platform A and 102U on Platform B. You might immediately think: buy here, sell there, and you make 2U per coin, right?
This idea is called cross-platform arbitrage, but the price difference on screen isn’t profit in your pocket yet.
It’s like buying goods at a wholesale market and transporting them to another store to sell. Besides the purchase and selling prices, you also have to factor in shipping costs, time, and whether anyone will actually buy them once they arrive.
Trading fees, withdrawal fees, and the spread between execution prices will all eat into

Yesterday, I said there was little to expect from the interest rate decision, and indeed, there was not much movement!
I think Warsh's remarks were hawkish. Two phrases in his speech were particularly interesting: “heated debate” and “independent colleagues”!
I remember that in his second speech after taking office, Warsh also said he got along well with other Fed officials. This time, his remarks somewhat highlighted divisions within the Fed.
It seems Warsh's job at the Fed is not going smoothly, and his policies will face some degree of resistance. It also seems that since taking office, he

There’s still not much to expect from this Fed rate decision!
Warsh isn’t going to send signals to guide the market, and no rate hike this time is already priced in.
The key question is how other officials’ remarks at the meeting will affect the December rate decision, especially since oil prices haven’t actually fallen yet and Treasury yields have remained elevated. #美联储利率决议倒计时

Prada’s latest ad features a collaboration with legendary Disney animator John Pomeroy
He began drawing cartoons for Disney in 1973—you’ve definitely seen his work!
Pocahontas, The Land Before Time, and An American Tail are all his work
Traditional pencil-drawn 2D animation and sketches are woven into Prada’s live-action ad
The result feels just like watching Disney cartoons as a kid
The hand-drawn texture is also much easier on the eyes than today’s screens full of AI content

The Fed “Holding Steady”? Don’t Be Fooled by These Four Words
#美联储继续按兵不动
The Fed has “held steady” again. In the early hours of October 29 Beijing time, the federal funds rate was left unchanged at 3.75%–4%, in a 10-2 vote. At first glance, the market breathed a sigh of relief, as if the worst was over.
But break down the statement, and what lies beneath “no change” is not the prelude to easing, but a hawkish pause.
The most striking signal came from the two dissenting votes. In the usual script, dissent over a “hold” typically comes from those who think rates are too high and are eager to cu

There is something I have noticed about some Igbo politicians, and it is the ease with which they throw their own brothers under the bus just to please their political masters.
When I look at what Papa Ozona and Umahi are doing, someone might think they are acting this way because they have presidential ambitions. But honestly, I don't think that is the main reason. To me, it looks more like an attempt to gain Tinubu's attention and prove their loyalty to him.
Now, look at Governor Hope Uzodimma. In all honesty, I have never been his fan, but I have watched him closely since 2023, and I cannot

The airdrop has been announced. Is it still time to buy?
The group chat suddenly lights up: “Hold this coin to claim the airdrop!”
Just as you’re about to buy, pause and check the “snapshot time” in the announcement.
A snapshot is like taking a group photo: whoever is there when the shutter clicks gets recorded. Show up after the photo is taken, and you won’t automatically appear in it.
If the event is based on yesterday’s holdings, buying today usually won’t make up for yesterday’s eligibility. Some events also look at your average balance over a period of time, rather than how much you held

Seeing fees flow into the liquidity pool every day feels pretty good. But when you do the math, you realize that if you hadn’t deposited those coins and had simply held them, you might have more now.
This brings us to what people often call “impermanent loss.”
Take a common two-token automated market maker pool as an example. When the relative prices of the two tokens change, trading and arbitrage alter the asset ratio in the pool. When you withdraw, you may not get back the original quantities of each token.
Think of it as an automated exchange counter: when one token gets more expensive, tha

The same 1000U can have completely different outcomes. $DUSK Today’s -17.36% move is a textbook lesson. The current price is 0.0956, down from a 24h high of 0.1190 to a low of 0.0950, with 6.9M in trading volume—this isn’t a pullback; capital is voting with its feet.
First, look at the market: this morning, people were still calling for a “breakout” above 0.11. Now it’s at 0.0956, with a 25-point intraday range. Anyone who chased the price with 1000U is left with just 826U. What’s the key issue? The low of 0.0950 is right next to the current price, which shows that selling pressure hasn’t ful

Does exchanging old tokens for new ones and getting more mean you’ve made a profit?
You had only 100 coins in your account, and after the project upgrade, that became 1,000. First reaction: a tenfold increase?
Don’t celebrate just yet—check the conversion ratio.
Suppose the rule is 1 old coin for 10 new coins. If each old coin was worth 10U and each new coin is worth 1U, you had 1,000U before the exchange and still have 1,000U afterward.
