How Anthropic’s Mythos model is forcing the crypto industry to rethink everything about security
Anthropic's Mythos AI is forcing a security rethink in crypto.

Bitcoin's recent gains of nearly 15% this month are not enough to assure analysts that it has exited the bear market. Predictions suggest a potential drop to $40,000, which would be a statistically extraordinary event.

Bitcoin's BTC$77,688.21 recent gains — it's added almost 15% this month — aren't enough to convince some industry observers that the largest cryptocurrency has escaped the bear market it entered in October. It is, after all, still 40% below its record.
There may be deeper drops to come, with some, unidentified, forecasters, predicting a drop to as low as $40,000, a 70% drop from its all-time high. The figure comes from bitcoin analyst James Check, who says such a move is unlikely. While not impossible, he said in a post on X, it would be statistically extraordinary.
"Just to make a point, for the bears who want to see $40k.
You may well end up right. However, consider that on a mean reversion basis, averaging relative to nine anchors (a mix of technical, onchain, trend, fast, slow etc), it is a Q 0.4 event.
Lower than $2 Bitcoin in 2011."
After climbing over $126,000 in October, bitcoin slid more than 50% to around $60,000 in February before stabilizing. It was trading Friday near $78,000.
Talking to the bears, Check said their predictions warrant closer scrutiny.
Check points to the Bitcoin Mean Reversion Index, a composite model that averages multiple key valuation metrics, including the 200-week moving average, realized price, power law trend and a number of volume-weighted average price measures. The index ranks bitcoin’s price on a historical percentile basis.
When modeled at $40,000, bitcoin registers as a “0.4 event,” meaning it would fall in the 0.4th percentile of all daily closes.
“That’s below any meaningful deviation across all major anchors,” Check said.
For context, Check says that would be equivalent to bitcoin trading below $2 in 2011 on a relative basis. By contrast, today’s price sits around the 31.5th percentile, historically weak but within normal correction ranges.
“There’s no zero probability in markets,” Check added, “but this would be a near-unprecedented outcome.”

James Check believes that while a drop to $40,000 is possible, it would be statistically extraordinary and unlikely based on historical data.
Bitcoin has gained almost 15% this month, but it remains 40% below its all-time high.
Bitcoin climbed over $126,000 in October, then dropped more than 50% to around $60,000 in February before stabilizing near $78,000.
