History favors another weak Bitcoin H2 – Can liquidity rewrite BTC’s 2026 cycle?

The Bitcoin [$BTC ] halving is often misinterpreted as an instant price catalyst.

In reality, it works through a gradual supply reduction effect, supported by Bitcoin’s technical setup. Notably, major upside phases have occurred in the 12-18 months after a halving, rather than immediately. After the 2016 halving, for instance, Bitcoin saw its main expansion in 2017, gaining over 1,000%. Similarly, after the 2020 halving, the strongest upside played out through 2020-2021, with a full-cycle rally of roughly 60%.

By contrast, the second halves (H2) of 2018 and 2022 are widely viewed as late-cycle drawdowns. In 2018, Bitcoin fell 40%-45% in the second half of the year. In 2022, it fell 15%-20% before bottoming toward year-end. Taken together, it does appear that H2 weakness in those cycles reflects a “post-halving cooling phase.”
Bitcoin cycle tested as 2026 moves into H2 phase
The crypto market has officially stepped into the H2 phase of the 2026 cycle.

So far, the cycle structure is broadly tracking Bitcoin’s post-halving behavior seen in 2018 and 2022. Bitcoin is closing H1 down over 30%, which is similar in character to H1 2018 (down nearly 54%) and H1 2022 (down over 56%). In this context, 2026 looks consistent with a post-halving cooldown phase following the 2024 halving, which cut Bitcoin’s block subsidy from 6.25 $BTC to 3.125 $BTC per block.

If the same playbook holds, Bitcoin could be on track to close H2 in the red. This is also supported by K33 Research Senior Analyst Vetle Lunde, who noted:

The 2022 Bitcoin drawdown lasted for 286 days. In the 2014 and 2018 bear markets, the bottoms occurred 12-13 months after the bear markets began, with a max drawdown of 84-85%. If history is to repeat, a bottom could be expected to form near year-end.

In this context, the roughly 30% H1 drawdown this year can still be viewed as part of a broader post-halving cooldown phase.#Write2Earn $BTC
