Coinbase CEO Brian Armstrong made headlines this week predicting Bitcoin could reach $300,000 to $400,000 by 2030. Bold numbers like that always reignite the same debate in crypto circles: does the halving actually drive Bitcoin’s price up, and if so, when does the pump happen, before the event or after it?
The short answer is both, but not in the way most halving hype threads suggest.
What a halving actually is
Bitcoin’s code cuts the reward paid to miners in half roughly every four years, or every 210,000 blocks. It’s a hardcoded, predictable supply shock. Fewer new coins enter circulation daily once a halving hits, dropping from 900 BTC a day to 450 BTC after the most recent one in 2024. The logic is straightforward: if demand holds steady while new supply drops, price should rise. Basic economics.
But markets rarely move on logic alone, and Bitcoin’s four halvings so far tell a more complicated story than “halving happens, price moons.”
The case that halvings drive price up
Looking across all four cycles, a real pattern does emerge. Bitcoin gained roughly 9,300% in the 18 to 24 months after the 2012 halving, 3,200% after 2016, and 700% after 2020. Even accounting for diminishing returns each cycle (a natural effect of Bitcoin’s growing market cap), all three completed cycles ended in substantial rallies, and the 2024 halving continued that pattern too, with Bitcoin pushing to new all time highs above $100,000 before peaking around 18 months later.
Crucially, the rally doesn’t wait for the halving date itself. Analysis going back to 2011 shows Bitcoin’s price was already climbing in the year before each halving, not just after. The market prices in scarcity ahead of time rather than reacting only once the supply cut is live.
The case for skepticism
Here’s where the balance comes in. The immediate aftermath of a halving is often unremarkable, or even negative. After the 2016 halving, Bitcoin saw a 27% drawdown shortly after the event rather than an instant rally. In 2016’s case, price barely moved for months before the real rally began. The pumps that made headlines came well after the halving date, not because of it directly.
There’s also a structural problem with using four data points to draw firm conclusions. Every halving happened under wildly different market conditions. The 2012 halving predated any institutional interest in Bitcoin entirely. The 2020 halving landed in the middle of a pandemic with unprecedented global stimulus flooding into risk assets. The 2024 halving came after the launch of spot Bitcoin ETFs in the US, an entirely new category of institutional demand that didn’t exist in previous cycles. Each cycle’s rally could just as easily be explained by these external forces as by the halving mechanism itself.
Add to that the diminishing returns each cycle (9,300%, then 3,200%, then 700%, then a comparatively modest run in 2024/2025) and a reasonable read is that the halving’s raw supply effect matters less each time, as Bitcoin’s market cap grows too large for a single mining reward cut to move the needle the way it once did.
The current cycle adds another wrinkle. Unlike the near zero interest rate backdrop of 2012, 2016, and 2020, the 2024 to 2026 cycle has played out against one of the highest interest rate environments since 2007, a meaningfully different macro backdrop that makes historical comparisons even shakier.
Where this leaves Armstrong’s $300k to $400k call
Armstrong’s prediction sits within the range this halving pattern would suggest, if you assume the cycle repeats in some form even at a diminished scale. But as the replies under the Watcher.Guru post note, the real question isn’t the target number, it’s what has to happen to get there: continued institutional adoption, deeper liquidity, or genuinely new sources of demand beyond what ETFs have already brought in.
The halving is real, the supply cut is real, and the historical rallies are real. What’s far less certain is how much of the credit belongs to the halving itself versus everything else happening in the world at the same time. Four data points, four different macro environments, is a thin foundation for a $400,000 price target, however reasonable the underlying logic sounds.
