What Is the Bid-Ask Spread? Why Can an Apparently Small Spread Keep Affecting Returns from High-Frequency Trading and Frequent Entries and Exits?
In cryptocurrency trading, many people focus only on price movements and overlook the spread between buying and selling. Even if the market price does not change significantly, traders may still incur real costs from the bid-ask spread and fees. The more trades you make, the more these costs matter.
First, what is the bid-ask spread?
The bid-ask spread is the difference between the current lowest ask and highest bid. For example, if the highest bid f

BYD has surpassed 1.02 million employees, including as many as 120k R&D engineers, and has been the global new energy vehicle sales champion for four consecutive years.
A workforce of over one million is comparable to a city, and 120k R&D engineers demonstrate BYD's commitment to investing in technology. Its position as a leader in the new energy vehicle sector will be difficult to challenge in the short term.

What is trading system backtesting? How can historical data be used to test a strategy instead of judging its effectiveness based only on intuition?
In cryptocurrency trading, a strategy that seems logical is not necessarily profitable. Trading system backtesting applies clearly defined trading rules to historical market data to simulate past trades and assess a strategy’s returns, risks, and stability.
First, what should be defined before backtesting?
First, define the trading instrument, time frame, entry conditions, stop-loss and take-profit rules, position size, and exit conditions. The ru

The roadmap is packed—but how much has actually been delivered?
An upgrade in Q1, applications launching in Q2, and ecosystem expansion in Q3. After reading the project roadmap, it feels like something major is happening every month.
But a roadmap is a bit like a renovation schedule: saying “the place will be ready by the end of the month” is one thing; actually getting the keys, having the water and electricity hooked up, and being able to move in is another.
To assess a project’s progress, break its goals down into three questions: What did it originally promise to do? What has it delivered

If you buy RWA tokens, do you own real-world assets?
When you see “real estate on-chain” or “gold tokens,” it’s easy to assume that buying the tokens means you own a share of a real-world property or gold.
But what you actually get depends on how the product is designed.
A property deed, a rental contract, and a membership card for a real estate company are all related to property, but they give you very different rights.
RWA refers to real-world assets. Related tokens may represent rights to assets, fund shares, or debt claims, or they may simply be the governance token of an RWA platform. Be

After trading on Polymarket for two years, this guy probably still doesn't know what losing feels like.
99% win rate.
That means he only loses 1 out of every 100 trades.
I don't think that's enough for him to really know what it feels like to take a hit.
And he's already made $932,714 in net profit.
His wallet:
His strategy is ridiculously simple.
He buys near-certain outcomes for $0.95 to $0.99, then waits for them to settle at $1.
While others chase 100x returns, he quietly prints money on the most obvious outcomes.

Can my collateral be liquidated even if I haven’t opened a futures position?
“I only used ETH as collateral to borrow some stablecoins. I didn’t open a futures position, so why do I still need to monitor my position?”
Because the loan is still outstanding, while the price of your collateral can change.
For example, when you posted the collateral, this batch of ETH was worth 2000U, and you borrowed 1000U. Later, the collateral falls to 1400U, but the loan principal doesn’t automatically drop to 700U, and interest may continue to accrue.
At that point, the collateral provides less coverage for t

So much for smart collaboration—the very first step brings back the fear of being ruled by the Windows Registry.
