画出比特币的未来——对数增长模型

币界网报道:

探寻比特币增长趋势和价格规律一直是这个领域研究的圣杯。这一类的研究多如牛毛,从S2F模型到梅特卡夫模型,从供需关系到哈希率,视角的不同导致了模型参数维度的不同,参数维度的不同也就从根本上决定了模型对比特币规律解释力的千差万别。

从本文开始我会介绍一些主流的比特币价格分析框架,作为第一篇我想先用一种比较直观的方式来介绍比特币对数增长模型。这里不会设计太多公式计算和代码。

同时感谢X上apsk32网友制作的动画。下图为整体的对数增长模型动画,我将其分解逐步分析其所想表达的含义。

让我们开始吧。

  1. 先对数处理——改变数据形式,重新理解比特币价格规律

对比特币价格进行取以10为底的对数,你可以看到Y轴的标注以10的指数级增量为单位且每一个刻度中密度也不一致,这也是对数函数的特性。

2. 数据拟合,找到比特币支撑线

使用线性回归方法对转化后的数据进行拟合就可以找到最佳匹配的直线(直线公式在图中已经标注),也就是支撑线,表现了比特币的价格在该模型下理论最低点。

这条线在现实操作中的含义很简单:如果低于这条线,市场大概率已经出现恐慌性抛售,购入的最佳时机已经出现。

3.根据支撑线,找到价格上限,确定周期规律

利用支撑线计算价格与支撑值的比率。在上图中可以明显看出,比特币价格相对于支撑线在牛市期间飙升,而且这些高峰值在每个周期中都在下降。同样,我们也可以获得价格上限函数。这个指数函数将使我们能够推导出价格的上限。

这个动画想表达的意思是:随着时间的推移,比特币在周期内最高值正在逐渐减少,也就是每一轮回的最高值都在减少。(当然,这里其实可以通过振荡器数值的计算来得出最高值在减少的规律,下图是我用本月初数据进行的拟合)

4. 根据上限函数反推得到价格上限

如果你知道价格/支撑上限的方程,那么你可以通过将其与支撑线的值相乘来计算价格的上限。(价格/支撑上限)× 支撑 = 价格上限。

所以这个图表示了如果未来比特币的价格超过价格上限,则属于市场处于超买状态,需要择机离场了。

5. 将4个周期内的线条归集将大致得到下一周期的走势

将前四个周期内的线进行平移,移入到我们当前所处的第五个周期内,然后进行平均,我们将看到价格未来走势可能会是什么样子。

所以这位X平台的apsk32的网友对于未来总结说:如果价格/支撑比率趋势继续,这一周期将在 2025 年达到 $160,000 到 $190,000 之间的峰值。有些人可能会认为这是看跌的,但这一趋势也表明比特币在 2030 年代将突破一百万美元。

这就是一个简版对数模型的分析。网友在给这个图标注了幂律模型,这其实是不对的,幂律模型是对比特币价格以及时间进行双对数处理,单一对数处理是对数增长模型。

最后,无论怎么样,模型终归是基于历史数据对未来的模拟。但未来往往不可预测,但我们可以尝试去寻找那个韵脚。

The Full Story of How Crypto Unicorn Blockstream Is Mired in Serious Fraud Allegations

This article details serious allegations of fraud against Bitcoin infrastructure company Blockstream, founded by Bitcoin pioneer Adam Back. In June 2024, investigative account NatInfoSec published a report accusing Blockstream's mining note (BMN) program of potentially operating a multi-billion dollar scheme with Ponzi-like characteristics. The core allegations focus on Blockstream Mining Notes (BMNs), which offer investors fixed annual yields up to approximately 20% from Bitcoin mining. NatInfoSec's investigation raises several key issues: 1. **Suspicious Hashrate & Payout Capacity**: The analysis suggests Blockstream would need 20-45 EH/s of mining power to cover its BMN obligations, but its public dashboard shows only around 15 EH/s. Furthermore, no verifiable public evidence (e.g., grid connection records, import data) was found to support the massive mining operation required. 2. **Questionable Payout Source**: The BMN contract allows Blockstream to use Bitcoin from *any source* (Substitute Performance BTC) to fulfill investor payouts, raising concerns that payouts may not come from actual mining revenue. 3. **High-Risk, Fixed Returns**: Offering ~20% fixed yields in the volatile, cyclical Bitcoin mining industry is viewed as highly unusual and requires clear explanation. 4. **Undisclosed Criminal Record of Key Figure**: Christopher William Cook, a key figure in Blockstream's mining operations and CEO of spin-off Exacore, was found to have a federal felony conviction for mail fraud in 2008, a fact not disclosed in BMN offering documents. His background was also allegedly embellished. 5. **Potential Contagion to BSTR SPAC**: Questions were raised about whether these liabilities and Cook's record should have been disclosed in the SEC filings for Bitcoin Standard Treasury Company (BSTR), a separate Adam Back-associated firm planning a SPAC merger. The crypto community is divided. BitMEX Research validated Cook's criminal record and expressed concern over the high yields but found other evidence lacking or misleading, noting the legal separation between BMN, Blockstream, and BSTR. Blockstream defenders, like Samson Mow, argue the mining is real. Critics, however, emphasize the lack of independent, verifiable proof of the mining operation's scale and the true source of investor payouts. The article concludes that BMN remains shrouded in key unanswered questions regarding its actual size, the verifiability of its underlying mining assets and payouts, the source of its high yields, and the full role and disclosure concerning Chris Cook. Blockstream had not issued a comprehensive response at the time of writing.

DIGITAL GOLD ($BITCOIN): A Comprehensive Analysis Introduction to DIGITAL GOLD ($BITCOIN) DIGITAL GOLD ($BITCOIN) is a blockchain-based project operating on the Solana network, which aims to combine the characteristics of traditional precious metals with the innovation of decentralized technologies. While it shares a name with Bitcoin, often referred to as “digital gold” due to its perception as a store of value, DIGITAL GOLD is a separate token designed to create a unique ecosystem within the Web3 landscape. Its goal is to position itself as a viable alternative digital asset, although specifics regarding its applications and functionalities are still developing. What is DIGITAL GOLD ($BITCOIN)? DIGITAL GOLD ($BITCOIN) is a cryptocurrency token explicitly designed for use on the Solana blockchain. In contrast to Bitcoin, which provides a widely recognized value storage role, this token appears to focus on broader applications and characteristics. Notable aspects include: Blockchain Infrastructure: The token is built on the Solana blockchain, known for its capacity to handle high-speed and low-cost transactions. Supply Dynamics: DIGITAL GOLD has a maximum supply capped at 100 quadrillion tokens (100P $BITCOIN), although details regarding its circulating supply are currently undisclosed. Utility: While precise functionalities are not explicitly outlined, there are indications that the token could be utilized for various applications, potentially involving decentralized applications (dApps) or asset tokenization strategies. Who is the Creator of DIGITAL GOLD ($BITCOIN)? At present, the identity of the creators and development team behind DIGITAL GOLD ($BITCOIN) remains unknown. This situation is typical among many innovative projects within the blockchain space, particularly those aligning with decentralized finance and meme coin phenomena.

The available information indicates that DIGITAL GOLD ($BITCOIN) does not have any known institutional backers or prominent venture capital investments. The project seems to operate on a peer-to-peer model focused on community support and adoption rather than traditional funding routes. Its activity and liquidity are primarily situated on decentralized exchanges (DEXs), such as PumpSwap, rather than established centralized trading platforms, further highlighting its grassroots approach. How DIGITAL GOLD ($BITCOIN) Works The operational mechanics of DIGITAL GOLD ($BITCOIN) can be elaborated on based on its blockchain design and network attributes: Consensus Mechanism: By leveraging Solana’s unique proof-of-history (PoH) combined with a proof-of-stake (PoS) model, the project ensures efficient transaction validation contributing to the network's high performance. Tokenomics: While specific deflationary mechanisms have not been extensively detailed, the vast maximum token supply implies that it may cater to microtransactions or niche use cases that are still to be defined. Interoperability: There exists the potential for integration with Solana’s broader ecosystem, including various decentralized finance (DeFi) platforms. However, the details regarding specific integrations remain unspecified. Timeline of Key Events Here is a timeline that highlights significant milestones concerning DIGITAL GOLD ($BITCOIN): 2023: The initial deployment of the token occurs on the Solana blockchain, marked by its contract address. 2024: DIGITAL GOLD gains visibility as it becomes available for trading on decentralized exchanges like PumpSwap, allowing users to trade it against SOL. 2025: The project witnesses sporadic trading activity and potential interest in community-led engagements, although no noteworthy partnerships or technical advancements have been documented as of yet. Critical Analysis Strengths Scalability: The underlying Solana infrastructure supports high transaction volumes, which could enhance the utility of $BITCOIN in various transaction scenarios. Accessibility: The potential low trading price per token could attract retail investors, facilitating wider participation due to fractional ownership opportunities. Risks Lack of Transparency: The absence of publicly known backers, developers, or an audit process may yield skepticism regarding the project's sustainability and trustworthiness. Market Volatility: The trading activity is heavily reliant on speculative behavior, which can result in significant price volatility and uncertainty for investors. Conclusion DIGITAL GOLD ($BITCOIN) emerges as an intriguing yet ambiguous project within the rapidly evolving Solana ecosystem. While it attempts to leverage the “digital gold” narrative, its departure from Bitcoin's established role as a store of value underscores the need for a clearer differentiation of its intended utility and governance structure. Future acceptance and adoption will likely depend on addressing the current opacity and defining its operational and economic strategies more explicitly. Note: This report encompasses synthesised information available as of October 2023, and developments may have transpired beyond the research period.
