Blockchain Center Signals 3-Day Altcoin Season: Reality or Mirage?
The altcoin season continues to thrive, and cryptocurrency enthusiasts on social platforms are celebrating the surge in prices. Data from Grok indicates that X feeds are alive with activity, featuring numerous posts that support this trend. As per Grok's findings, the surge in social media discussions coincides perfectly with the Altcoin Season Index (ASI) surpassing the 75 out of 100 threshold on September 10.

At the same time, while the ASI indicates an altcoin season, many skeptics claim they just can’t perceive it. “Holy sh**, the Altcoin Season Index just reached 84 – the highest this year,” exclaimed influencer Lark Davis on X. However, not everyone is persuaded, as one user retorted: “Where is altcoin season? I can’t see it.”

Some believe this current altcoin season is merely a temporary phase, unlikely to last long. “This altcoin season is predicted to endure for 5 days,” cautioned one X user. “Take profits — something bad is on the horizon.” As of Sept. 13, 2025, at 4:23 p.m. Eastern, archived data reveals that blockchaincenter.net’s ASI is steady at 80.

It might be a month of altcoin season, but it’s certainly not an altcoin season year. The site’s monthly score stands at 88 out of 100, while the 12-month score lags behind at just 35. Since any score above 75 indicates an altcoin season, this suggests that three-quarters of the top 50 altcoins have outperformed bitcoin’s market performance over the past 90 days.

The recent surge in altcoin season has fans rejoicing, yet a sense of caution remains. The cycle of excitement followed by diminishing momentum has recurred since 2021, leaving traders cautious and yearning for a prolonged season. So far, this one has climbed nearly as high as it did in December 2024. Whether this moment marks a significant change or yet another brief surge, only time will reveal the true trajectory of the crypto market ahead.

Qubic’s Claim of a 51% Attack on Monero Ignites Security Concerns
The recent assertion by the mining pool Qubic regarding a 51% attack on Monero has left advocates for privacy and blockchain technology feeling uneasy, prompting discussions about the security measures that safeguard blockchain systems. Although the community has largely dismissed the notion of a sustained attack, this event has brought to light a persistent vulnerability in Monero that could be exploited by a determined adversary using standard hardware.

Joel Valenzuela, a key member of the Dash decentralized autonomous organization (DAO), states that an attacker can easily disrupt the network with conventional mining equipment. While the uproar has calmed down, Valenzuela cautions that the Monero network is still at risk.

"To be frank, the issue remains unresolved and unaddressed at this moment," Valenzuela warned. "The blockchain reorganizations have either slowed or become sporadic, but the potential for these reorganizations to restart or escalate is still very much present."

Valenzuela concurs with other analysts that Qubic might have successfully mined a majority of blocks during specific intervals. However, he informs Bitcoin.com News that he is uncertain whether Qubic could maintain this for an extended duration, which has led some to question the mining pool’s decision to publicly announce an unverified claim.

Motives Behind the Attack and the Dash Alternative
In his written responses, Valenzuela theorizes that Qubic went public to attract attention to their relatively new cryptocurrency initiative. He believes that if this was indeed Qubic’s intention, it has been remarkably successful. He also suspects that financial motivations were involved, pointing out that Qubic seems to utilize excess computing power to mine other cryptocurrencies such as Monero, which provides a financial incentive for the attack.

In response to reports that Dash had intervened to assist Monero, Valenzuela clarified that although both chains were developed to rectify shortcomings in the Bitcoin network, they took different paths in 2019. That year, Dash introduced Chainlocks to utilize staked masternodes, effectively preventing 51% attacks. Conversely, Monero adopted Randomx, which not only eliminated ASICs but also made mining more accessible. Valenzuela argues that this change rendered Monero less secure and more vulnerable to attacks like the one launched by Qubic.

"For Monero to integrate a technical solution akin to Dash’s ChainLocks, it would necessitate a substantial technical overhaul, but it would prevent an external entity from attacking the network without also possessing a considerable portion of Monero’s coin supply," Valenzuela asserts.

Regulatory Challenges and the Need for Transparency
Valenzuela also spoke about the regulatory environment, emphasizing that it is the user's duty to ensure compliance when utilizing privacy networks. Nonetheless, he expressed frustration over the sluggishness of regulators in creating necessary frameworks, which he feels is obstructing wider adoption.

"To be frank, I find the reasons given by regulators for their slow approach to cryptocurrencies, particularly regarding consumer protection, to be unconvincing," he stated.

Valenzuela contends that rather than adding more obstacles, lawmakers should work towards decriminalizing cryptocurrency use by offering clear legal guidelines. He pointed to the recently enacted Clarity Act in the U.S. as a model for how other regions should establish a definitive legal structure.

Chatbots Forecast BTC Surge: $114K to $180K by December
We revisited a variety of AI chatbots to evaluate their predictions for BTC’s path in the fourth quarter. Insights were gathered from models like Musk's Grok, OpenAI's ChatGPT, Venice AI, Anthropic's Claude, Deepseek, and others to encompass a broad spectrum of views on the upcoming months.

Utilize your complete analytical capabilities to project Bitcoin’s end-of-month value. Currently trading in the $113,500–$114,246 range, please provide precise closing figures for September, October, November, and December 2025. Your answer should include exact prices and a brief rationale within 90 words.

ChatGPT 5 thinking mode response:
Estimates (EOM closes):
Sep 2025: $120,900; Oct 2025: $128,700; Nov 2025: $123,200; Dec 2025: $131,800.

Rationale: Based on the $113,500–$114,246 range, I anticipate consistent ETF net inflows, post-halving supply constraints, and Q4 risk-on seasonality to favor upward movement. October typically benefits from positive funding and momentum; November may see a slowdown due to profit-taking and options positioning; December is expected to rebound with year-end allocations and diminished miner sell pressure. This assumes no significant regulatory or macroeconomic shocks.

Deepseek with Deepthink response:
September: $118,500 (momentum from current range)
October: $125,200 (institutional inflow acceleration)
November: $134,800 (post-election volatility & ETF demand)
December: $141,500 (year-end portfolio rebalancing & cycle peak anticipation)

Rationale: Anticipated gains are fueled by ongoing institutional ETF adoption, macro liquidity support, and the usual pre-halving year acceleration, which should mitigate short-term volatility. Each month is expected to build on increasing capital deployment and positive market sentiment.

Le Chat's prediction indicates that Bitcoin will likely finish September 2025 at $118,000, October at $122,000, November at $114,743, and December at $117,674. These projections suggest a bullish trend, driven by institutional ETF inflows and favorable macroeconomic conditions, although November and December might experience some consolidation or slight pullbacks. Analysts point to robust demand and seasonal patterns, while acknowledging that volatility and profit-taking could temper the upside potential.

ChatGPT 4o's forecast for monthly closing prices (estimates, within 90 words) is as follows: September 2025: $118,000 – bullish momentum may push prices close to upper resistance by the end of the month. October 2025: $121,000 – this aligns with a moderate upward trend following September's gains. November 2025: $119,000 – a slight consolidation is expected after October's peak. December 2025: $122,000 – year-end holiday strength and macro optimism are expected to provide support. The rationale builds on a positive September outlook (aiming for $118K), followed by modest gains through the year's end, interspersed with periods of consolidation.
