Bitcoin declined in both Q1 and Q2 of 2026, marking only the third time in its history that it has started a year with two consecutive quarterly losses. In the two earlier instances—2018 and 2022—the second half failed to deliver a meaningful rebound.

Bitcoin (BTC) closed the first half of 2026 in negative territory across both quarters, making it one of the rarest weak starts on record. The asset fell 22.2% in the first quarter and a further 14.09% in the second, according to Coinglass data, and was trading just above $59,000 at the start of Q3 on Wednesday.

Only twice before has bitcoin opened a year with back-to-back quarterly losses, in 2018 and 2022—both of which went on to become some of its worst annual performances.

In those cycles, the second half offered little relief. In 2018, a small 3.6% gain in Q3 was followed by a sharp 42% drop in Q4. In 2022, Q3 declined 2.6% and Q4 fell nearly 15%.

Both periods were shaped by broader bear-market forces—2018 following the collapse of the ICO boom, and 2022 driven by the unraveling of Terra and the failure of FTX.

Bitcoin’s typical seasonal pattern points in the opposite direction. Historically, Q4 has been its strongest quarter, averaging a 77% gain with a median near 48%, often helping offset earlier declines. Q3, by contrast, tends to be the weakest and often produces muted or negative returns.

However, in both 2018 and 2022, those seasonal tendencies broke down as deep bear markets overwhelmed normal cycles, turning the usually strong fourth quarter into a period of heavy losses.

While the sample size is limited, the comparison suggests that such weak first-half performance has historically aligned with more structural downturns rather than short-term corrections.

Whether 2026 follows a similar trajectory remains uncertain, with current selling pressure appearing steady rather than panic-driven.

Recent data shows persistent outflows from U.S. spot bitcoin ETFs, subdued onchain activity, and a rotation of capital into AI equities, which have outperformed strongly while crypto has lagged.

A stronger U.S. dollar—further supported by the yen’s fall to a 40-year low—has added additional pressure on risk assets.

FxPro analyst Alex Kuptsikevich has flagged $40,000 as a key downside support level if weakness deepens. The third quarter has opened with a modest gain of around 1%, leaving the broader direction still unclear.
