Bitcoin bottom countdown nears 50 days after supply in loss

The bitcoin bottom countdown nears 50 days after more than half of Bitcoin's circulating supply first moved into loss on June 5, 2026—a classic on-chain signal that has historically preceded macro bear-market bottoms within 13 to 101 days in prior cycles. On-chain data tracked by K33 Research and CryptoQuant shows 42 days have elapsed since that threshold was crossed, placing BTC in its second-longest bear-market bottom window on record.

Key Takeaways

• Bitcoin supply in loss crossed 50% on June 5, 2026, the first time this bear market.
• 42 days have passed since the signal, making this Bitcoin's second-longest bottom countdown on record.
• Historically, BTC macro bottoms followed within 13 to 101 days after half the supply went underwater.
• K33 Research flagged the milestone in its H1 2026 Round-Up report as a classic late bear-market indicator.
• CryptoQuant data showed supply in loss at 46% on July 17, with analysts still watching seller exhaustion.

What triggered the bitcoin bottom countdown?

Bitcoin (BTC) has spent nearly two months in a phase that on-chain analysts treat as a countdown toward a macro bear-market bottom. In early June, the share of circulating BTC held below its purchase price — known as supply in loss — passed 50% for the first time in this cycle.

That development mirrored patterns seen in prior downturns. Crypto research firm K33 Research highlighted the shift in its H1 2026 Round-Up, noting that more than half of all Bitcoin was underwater. The metric is widely used to gauge how far a bear market has progressed and whether selling pressure may be nearing exhaustion.

Separate data also suggests the bull market's emotional premium has faded, reinforcing the view that sentiment has cooled sharply from earlier highs. For readers tracking broader market risk, our Fintech & Crypto Alerts hub covers related on-chain and regulatory developments as they break.

How long until Bitcoin usually hits a bear-market bottom?

Once supply in loss crosses 50%, historical bear markets have bottomed within a relatively narrow window. K33 data shows the floor arrived no more than 101 days after the threshold in every prior cycle measured.

The shortest gap was 13 days during the November 2022 downturn. The 2018 bear market needed 23 days, while the cycle following 2017 took 31 days. The 2014 cycle was the outlier: Bitcoin kept falling for 101 days after half the supply went underwater, and it was the only period where BTC was lower one year later.

With 42 days already elapsed in 2026, this countdown ranks as Bitcoin's second-longest on record — trailing only the 2014 episode. That does not guarantee an immediate reversal, but it places the market deep into territory that previously preceded macro lows.

Why does this countdown matter for crypto investors now?

Investors watch supply in loss because it captures how many holders are sitting on red positions. When a majority of coins are underwater, capitulation and ownership transfer often accelerate — conditions that have historically preceded cycle bottoms.

Axel Adler Jr., a contributor to on-chain analytics platform CryptoQuant, estimated earlier this month that supply in loss was roughly two months away from levels that correspond to past bear-market floors. CryptoQuant's July 17 reading put the figure at 46%, slightly below the June peak but still within the range analysts monitor closely.

None of this data calls a bottom on its own. Still, the countdown is one of the most closely watched on-chain signals in the current cycle, and analysts are tracking whether seller exhaustion builds before the historical 101-day ceiling.

What should traders watch in the weeks ahead?

The key variable is whether seller exhaustion accelerates before the historical 101-day ceiling. Continued updates from firms like K33 and CryptoQuant will help confirm whether the countdown is nearing its end.

Until then, the supply-in-loss signal remains a major on-chain marker that Bitcoin's bear-market bottom window is open — and that the market may be measuring its next major turn in days, not months.
