Living Off Bitcoin: What It Really Takes

Short answer: To live off bitcoin you need four things: holdings that carry your spending for about 25 years even at the floor price, a buffer of about two years' spending in euros or francs for the bear market, fixed selling rules and a plan for taxes and health insurance. For €3’000 a month, that is about 15 BTC today.

The dream and the math

You have held bitcoin for years, your holdings have grown, and at some point the thought comes: could I live off this? Quit, work less, use the time for other things. For many bitcoin holders, that is the real reason they save.

The honest answer: it can work, but not with the holdings that felt like enough at the last high. If you want to live off bitcoin, you have to sell every month, even when the price has just fallen by half. The plan has to be built for that.

This article shows what it takes: how much bitcoin, how much cash alongside it, which rules and which costs many forget. If you want to know how many sats you need to fill a gap next to the state pension, read How many sats do I need for retirement? first. Here it is about more: living entirely or largely off bitcoin, often long before retirement age.

What it means to live off bitcoin

Bitcoin pays no interest and no dividend. If you live off it, you sell. Every month in which you spend €3’000 costs you an amount of bitcoin that depends on the price:

If the price halves, you sell twice as many sats for the same rent. You are missing those sats when the price recovers. That is the core of the problem, and it is biggest when the bear market comes shortly after you stop working.

How much bitcoin you need to live off it

The simplest planning figure: your holdings should cover 25 years of spending, calculated at the floor price of the Power Law model. That corresponds to withdrawing 4% a year when bitcoin is at the floor. The floor lies at 42 % of the Power Law line; bitcoin has rarely been below it so far. How the model is calculated is in the methodology.

On Nov 12, 2026, the floor was €60’516 or CHF 55’868, the trend €98’116. That gives:

As of Nov 12, 2026. Source: model values from /power-law/btc-daily.csv, converted at the ECB reference rates of Nov 12, 2026 (€1 = $1.1081 = CHF 0.9232).

The "at the floor" column is the cautious number. With it, your holdings are enough even if you stop working right at the bottom of a bear market. The "at the trend" column only applies if the price is at a normal level when you stop. On Nov 12, 2026 it stood at 0.66 times the trend, so almost at the floor.

Living partly off bitcoin lowers the number a lot. If you earn €1’500 a month from part-time work or self-employment, then with €3’000 of spending bitcoin only has to carry half, so about 7.4 BTC at the floor. For many, that is the more realistic route.

The requirement also falls over time if the model keeps holding: if you only stop in ten or twenty years, you need considerably less bitcoin for the same spending. That is shown by the table in the article on retiring with bitcoin.

The buffer: how long a bear market lasts

The most important building block besides the holdings is cash. With a buffer in euros or francs you pay your expenses while bitcoin is cheap, and only sell again once the price has recovered.

How big the buffer needs to be depends on how long bitcoin stays cheap. The longest periods since 2013 in which the price was below 0.8 times the trend, that is clearly below fair value:

As of Nov 12, 2026. Source: our own analysis of daily closing prices in US dollars from /power-law/btc-daily.csv.

A 24-month buffer would have covered every phase except the one from 2015 to 2017. Since Oct 7, 2026 the price has been below the threshold again. How much longer that will go on, nobody knows.

With and without a buffer: an example from the 2021 high

Lena stops working on Nov 8, 2021. That day bitcoin is at its then record high of $67’525, about €60’938. She has €900’000 and wants to spend €3’000 every month. That is exactly the rule of thumb of 25 years of spending, just bought at the peak price: the worst start imaginable.

From July 2022 to November 2023, Lena lived off the buffer for 17 months in a row. At the tightest moment, in November 2023, €21’000 was left, seven months of spending. In December 2023 the price was back above 0.8 times the trend, and she refilled the buffer. In 2026 she has lived off it in seven of eleven months so far; on Nov 12, 2026 it still lasts 23 months.

The example shows two things. First: even without a buffer, Lena is not broke after five years, because she started with 25 years of spending. Second: the buffer was tight. With only one year of buffer it would have been empty in June 2023, and she would have had to sell at the bottom for five months until November 2023.

Fixed rules for selling

If you live off bitcoin, you sell every month. Without rules, every sale becomes a price decision, and those are made badly in a bear market. Good rules are simple and written down in advance:

1. Only sell above a fixed threshold. For example: bitcoin is only sold when the price is at least 0.8 times the trend. Below that, the buffer pays. Where the price stands today is shown on the Power Law page.
2. Refill the buffer when things go well. When the price is above the threshold, you sell enough for the buffer to cover two years of spending again.
3. Sell bigger, sell less often. One sale per quarter instead of every month saves fees and nerves.
4. Adjust spending when the buffer shrinks. If it falls below one year, you spend less. If you can save 10%, you extend the buffer by several months.
5. Check once a year. Do your holdings still cover 25 years of spending at the current floor? If not, you need more income or less spending.

How to write down and stick to rules for your goal is explained in the guide Setting and planning your bitcoin goal. Why rules matter more than courage in a crash is shown in FOMO, panic and capitulation.

The costs many forget

If you are employed, you pay health insurance and pension contributions through your salary without noticing. If you live off bitcoin, you pay them yourself. These costs belong in your monthly spending before you read the table above.

Germany

• Taxes: gains on bitcoin you have held for more than a year are tax-free (§ 23 EStG, as of 2026). If you sell younger coins, gains of €1’000 or more a year are fully taxable. So if you live off bitcoin, you only sell old coins and keep the purchase records ready. Everything else is in Bitcoin taxes in Germany.
• Health insurance: without employment you are voluntarily insured in the statutory health insurance system and pay the full contribution yourself. Even the minimum contribution is just under €300 a month in 2026. Your insurer checks which income to count using your tax assessment. Before you stop working, ask how it treats bitcoin sales.
• Pension: without contributions you no longer collect pension points. Voluntary contributions to the state pension insurance are possible.

Austria

• Taxes: gains on bitcoin bought after Feb 28, 2021 are taxed at 27.5%, however long you hold them (as of 2026). Older bitcoin are tax-free after one year. With newer coins, plan to sell correspondingly more.
• Health insurance: without employment you can insure yourself with the ÖGK (Austrian Health Insurance Fund) and pay the contribution yourself.

Switzerland

• Taxes: price gains on private wealth are generally tax-free. But your holdings are subject to wealth tax. Note: one criterion under which the ESTV safely assumes private wealth management is that capital gains make up less than 50% of your net income. If you live only off bitcoin sales, you don't meet it. That doesn't automatically make you a professional trader, but the tax authority then examines your individual case. What that looks like in numbers is shown in professional securities trading with bitcoin.
• AHV: if you are not gainfully employed before the reference age, you pay AHV contributions as a non-employed person, calculated from wealth and pension income. In 2026 that is at least CHF 530 a year, considerably more with large wealth.
• Health insurance: you pay the premium yourself anyway. Premium subsidies are usually not available with large wealth.

Other income besides selling

Selling is not the only way to get money out of bitcoin. Two options come up often, and both have their own risks:

• Borrowing against bitcoin instead of selling. You take out a loan with your bitcoin as collateral and pay your expenses from it. That way you sell nothing at the bottom. But if the price falls sharply, the lender demands more collateral or sells your bitcoin itself. What that costs and at what price it becomes dangerous is worked out in Borrow instead of selling.
• Digital Credit. Preferred stocks of bitcoin companies pay ongoing dividends. Strategy's STRC paid a variable 12% a year on Nov 12, 2026. That is not bitcoin in your wallet but a claim on a company. How it works and where the risks lie is explained in Digital Credit explained.

The simplest second income is still work. A small income that covers a third of your spending makes your plan sturdier than any financial construction.

Are you ready? The checklist

Many underestimate the last point. Living off bitcoin means watching a decline of 50 to 80% and still calmly paying the rent. How to practice that is explained in HODL psychology.
