On-chain Data Academy (Part Seven): A Brand New, Ark-involved $BTC Magical Pricing Methodology (II)
Original Article Title: "On-Chain Data Classroom (VII): A Brand New Set, Ark Participated Research on the Magical Pricing Methodology of $BTC (II)"
Original Article Author: Mr. Berg, On-Chain Data Analyst
If you are not familiar with Cointime Price yet, it is recommended to read the first article: "On-Chain Data Classroom (VI): A Brand New Set, Ark Participated Research on BTC's Magical Pricing Methodology (I)"
TLDR
- The Cointime Price series consists of three articles, this being the second article
- This article will introduce the application method of Cointime Price in top avoidance
- This article will introduce a personally designed deviation model
1. Brief Review of Cointime Price
The concept of Cointime Price originates from Cointime Economics, which evaluates BTC's fair price in a "time-weighted" manner.
Compared to simply Long-Term Holders (LTH) and Short-Term Holders (STH), Cointime Price is more elastic, sensitive, and can effectively exclude the influence of ancient lost BTC.
The first article detailed Cointime Price and its buy-the-dip application. If you already understand the concept, let's officially delve into today's topic: top avoidance application
2. Top Avoidance Application Methodology: Cointime Price Deviation Model Design
Cointime Price Deviation is one of the models I designed during my on-chain data research and has been applied in the weekly top avoidance analysis report.

The following text will explain the model's design principles and how to use the model to assess BTC tops. All content in this article is original research, the research process is not easy, so please show your support
1. Quantifying Current Price Deviation from Cointime Price
Why Measure Deviation?
- The Cointime Price highly represents the true holding cost of BTC chips, especially for Long-Term Holders (LTH).
- Since Long-Term Holders have a greater impact on the Cointime Price, when the BTC current price is significantly higher than the Cointime Price, the profit-taking motivation of Long-Term Holders increases, which may trigger distribution behavior.
· Calculation Formula: Deviation Rate = (Current Price - Cointime Price) / Current Price
· Observing Deviation Rate (Distribution Rate)

As shown in the chart, we can obtain the Distribution Rate curve (purple line). We can see that: whenever the Distribution Rate is at a high level, it often corresponds to the BTC top.
So, how do we define a "high level"? Next, we will use statistical methods to address this issue.
2. Cointime Price Deviation Extreme Value Definition
If we observe historical data, we will find that the high points of Deviation are not fixed; in each bull market cycle, the peak value of Deviation slightly decreases. Therefore, it is not rigorous to solely use a fixed numerical value to define a "high level."
To address this, I adopt the concept of statistical "standard deviation":
· Calculate the mean and standard deviation of historical Deviation data.
· Define "Mean + n standard deviations" as the "high level (top signal)," referred to as the Threshold.
· Smooth the Deviation data with a moving average to reduce noise.
· When the moving average value of Deviation> Threshold, trigger a top signal.
· Why Use Standard Deviation?
· The historical trend of Deviation exhibits mean reversion characteristics (as shown in the chart).
· Standard deviation measures volatility, so when BTC price volatility decreases, the Threshold will also dynamically adjust, providing more elasticity.

As shown in the above diagram, after the above processing, we can get such a diagram.
· Supplementary Explanation
- In point 2, "Mean + n Standard Deviations," n is an adjustable parameter: the larger n is, the lower the probability of vertex signal occurrence, and the model is more stringent.
- Point 3's moving average smoothing: mainly filters out short-term market fluctuations to improve signal reliability.

3. Top Escaping Signal Example
As shown in the figure, when the purple line (Distribution Ratio) exceeds the orange line (Threshold), the corresponding BTC price is often at a phase top.
III. Conclusion
This article is the second in the Cointime Price series, continuing the concepts of the previous article, sharing how individuals can design a top escaping model using Cointime Price.
· Summarize Core Points:
- Cointime Price Deviation quantifies the deviation of the current BTC price from the Cointime Price, speculating on the distribution motivation of long-term holders, used to determine the BTC top.
- The "Standard Deviation" method is used to dynamically define top signals to ensure the model is more adaptive.
- The model has been practically applied in weekly reports and can effectively capture BTC high-level signals.
Future Plans:
- The third article in this series will continue to explore the application of Cointime Price in escaping the top, so stay tuned.

WEEX P2P update: Country/region restrictions for ad posting
To improve ad security and matching accuracy, WEEX P2P now allows advertisers to restrict who can trade with their ads based on country or region. Advertisers can select preferred counterparty locations for a safer, smoother trading experience.
I. Overview
When publishing P2P ads, advertisers can now set the following:
Allow only counterparties from selected countries or regions to trade with your ads.
With this feature, you can:
Target specific user groups more precisely.Reduce cross-region trading risks.Improve order matching quality.
II. Applicable scenarios
The following are some common scenarios:
Restrict payment methods: Limit orders to users in your country using supported local banks or wallets.Risk control: Avoid trading with users from high-risk regions.Operational strategy: Tailor ads to specific markets.
III. How to get started
On the ad posting page, find "Trading requirements":
Select "Trade with users from selected countries or regions only".Then select the countries or regions to add to the allowlist.Use the search box to quickly find a country or region.Once your settings are complete, submit the ad to apply the restrictions.
When an advertiser enables the "Country/Region Restriction" feature, users who do not meet the criteria will be blocked when placing an order and will see the following prompt:
If you encounter this issue when placing an order as a regular user, try the following solutions.
Choose another ad: Select ads that do not restrict your country/region, or ads that allow users from your location.Show local ads only: Prioritize ads available in the same country as your identity verification.
IV. Benefits
Compared with ads without country/region restrictions, this feature provides the following improvements.
Aspect
Improvement
Trading security
Reduces abnormal orders and fraud risk
Conversion efficiency
Matches ads with more relevant users
Order completion rate
Reduces failures caused by incompatible payment methods
V. FAQ
