Bitcoin has a heartbeat that most retirement planners have never heard of. Roughly every four years, the flow of new Bitcoin gets cut in half, and the price has followed a recognizable rhythm: a bull run, a crash of 75 to 85 percent, a long grinding recovery, then a new bull run. If you retire at the wrong phase of that cycle holding money you plan to spend, you can be forced to sell at the bottom. That is the exact scenario the asset is supposed to protect you from. A home equity line of credit changes the entire math.
The Halving Cycle as a Planning Timeline
Every four years, the Bitcoin protocol halves the reward paid to miners. The supply squeeze that follows has historically kicked off a bull phase lasting 12 to 18 months. Then the cycle turns: a drawdown of 75 to 85 percent, a 12 to 18 month bear market, and a quiet accumulation phase before the next halving does it again.
| Cycle | Halving date | Cycle peak | Drawdown to the bottom |
|—|—|—|—|
| 1 | Nov 2012 | ~$1,150 (Nov 2013) | -85% to ~$170 (Jan 2015) |
| 2 | Jul 2016 | ~$19,700 (Dec 2017) | -84% to ~$3,200 (Dec 2018) |
| 3 | May 2020 | ~$69,000 (Nov 2021) | -77% to ~$16,500 (Nov 2022) |
| 4 | Apr 2024 | next cycle peak still unfolding | pending |
I have been a Bitcoiner since 2020, so cycle three is the one I watched in real time while building retirement income plans for a living. Three cycles is a short history and the pattern may not repeat. Keep that caveat in view. The strategy below is valuable even if the cycle never repeats cleanly, because the buffer it uses is worth having regardless.
Why the Phase at Retirement Matters So Much
Retirement advisors call it sequence of returns risk. The order in which good and bad years arrive can matter more than the average return itself. For a retiree holding one to five percent of a portfolio in Bitcoin, the cycle phase on the day you retire matters enormously.
Consider a retiree with a $750,000 portfolio, half a Bitcoin, and a $900,000 paid-off home who needs about $4,000 a month from somewhere. Whether they walked away from work in early 2022, early 2023, or late 2025 determined almost everything about how that half Bitcoin performed.
Three Retirements, One Asset
| | A: retire Jan 2022 | B: retire Jan 2023 | C: retire late 2025 |
|—|—|—|—|
| Bitcoin’s phase | immediately after the peak | near the cycle bottom | late bull phase |
| Without a buffer | selling ~0.24 BTC per month through the crash wipes out most of the position near $16,500 | portfolio withdrawals grind, but the Bitcoin rides the recovery | set up to repeat Scenario A whenever the next bear arrives |
| With a home equity buffer | draw ~$2,000 a month from the line of credit through 2022, sell nothing, and the full 0.5 BTC is still there at the April 2024 halving | draw from the recovering portfolio, leave the line of credit untouched and growing | the line of credit is already open and compounding before the next drawdown begins |
Scenario A is the horror story. Selling 0.24 BTC a month to cover income at falling prices drains nearly the whole position in two months of a deep bear market. Scenario B is dumb luck that looks like skill. Scenario C is where planning actually earns its keep, because the retiree who opens the buffer before the next bear is never a forced seller at all.
The Math of Selling at the Bottom
In January 2023, Bitcoin sat around $16,500. Raising $16,000 of income meant selling almost one full Bitcoin. That same coin was worth roughly $100,000 by December 2024. Every dollar of forced selling at the cycle bottom destroyed about six dollars of future value.
For our retiree with half a Bitcoin, the arithmetic is even uglier: at $16,500 the entire stack is worth $8,250. Funding even one month of income from it means liquidating nearly half the position.
Draw the same $16,000 from a home equity line of credit, repay it after the recovery, and the coins never leave your custody. The line of credit is non-recourse and cannot be frozen or reduced while you meet your obligations as a borrower, which matters because a HELOC can be taken away at exactly the wrong moment.
A Practical Framework for Retirees
The whole strategy compresses into three decision rules:
This is not market timing. You are not predicting anything. You are building a buffer so you never have to sell in the worst moments, the same discipline retirement planners apply to stock sequence risk. Bitcoin just concentrates the risk into a visible four-year rhythm that you can actually plan around.
Why Most Planning Software Misses This
Most retirement tools cannot model a cyclical hard asset alongside home equity and a traditional portfolio. That gap is why I built the Perpetual Retirement Stress Test: it puts three scenarios side by side, portfolio only, plus home equity, plus home equity and Bitcoin, with a real tax engine doing the math on every withdrawal. If you hold Bitcoin and own a home, it is the fastest way to see which phase of the cycle your own plan is exposed to.
