Taking Bitcoin Profits: Partial Sales by Rules, Not Emotions

Short answer: The best way to take bitcoin profits is in small parts, following rules you write down while the price leaves you cold. A good rule says four things: what triggers a sale, how much you sell each time, which core holding you never touch and what the money is for. Then, at the top, the plan decides, not greed.

Why almost nobody sells at the top

In November 2021 a bitcoin cost $67’525. Newspapers wrote about $100’000, friends asked you for advice, and your holding was worth more than ever. Few people sold in those weeks. A year later the price stood at $15’784, 77% lower.

The reason is simple: at the top, selling feels wrong. Every day of rising prices confirms that holding was right. If you set yourself a price target, you push it higher as soon as it's reached. And if you sell and then watch the price keep climbing, it hurts more than any sale you missed.

At the bottom it's the other way round: that's when many people sell who never meant to. How these mistakes happen is covered in FOMO, panic and capitulation. This article deals with the other side: how to take profits without relying on how you feel at the top.

The four parts of a selling rule

A rule that holds at the top answers four questions. Write down the answers before you need them.

1. Trigger: What has to happen for you to sell? A price, a goal reached, too large a share of your wealth.
2. Amount: How much do you sell per step? Small parts, for example 5% of your holding, and a cap per cycle.
3. Core holding: What do you never sell? Many holders set aside half or a quarter.
4. Use: What is the money for? For an expense, a buffer in euros or francs, or a later buy-back.

Without the fourth point, the proceeds sit in your account and get reinvested at the next dip, often at a higher price. A sale without a purpose is a trade, not a plan.

Three triggers for partial sales

1. A goal is reached

The best reason to sell is a goal that costs money: the rest of the mortgage, a degree, a year off. The rule then reads: "As soon as my bitcoin outside the core holding is worth that amount, I sell as much as the goal costs."

This rule depends on no model and no forecast. It only breaks if you move the goal as soon as you reach it. How to set such a goal in euros or francs is explained in the guide Setting and planning your bitcoin goal.

2. Bitcoin has grown too large

If you have decided that bitcoin should make up at most a certain share of your wealth, you sell as soon as that share is exceeded. Professionals call this rebalancing. It is the most sober rule: it sells automatically after strong rises and never in a crash.

How high your share should be is a separate question, answered in What percentage of your wealth in bitcoin?. The rule works with any number, as long as you set it in advance.

3. The price is above the top band

This site's Power Law sorts the price into five zones. For selling, the top two count:

The top band is the line through the earlier cycle tops. Today it is at 1.62 times the trend. It comes down toward the floor every year, ever more slowly, and never reaches it; the trend stays between the two. How it is calculated is explained in the methodology; today's zones are on the Power Law page. Why Hot and Euphoria move with the top band is explained in the article on the Power Law's valuation zones. How the top band is built and what sales in the Hot zone have brought so far is shown in The bitcoin top band.

A rule based on the model could read: "If the price closes above the top band, I sell 5% of my holding, at most once every 30 days." Here is how it would have played out in past cycles:

Source: daily closes from /power-law/btc-daily.csv, top band per today's model, as of Nov 12, 2026.

In 2021 the rule would have sold five times: on Feb 17 at $52’116, on Mar 19 at $58’026, on Apr 18 at $56’146, on Oct 15 at $61’692 and on Nov 14 at $65’500. 1 BTC would have become 0.774 BTC plus $13’208, on average 86% of the peak price.

The conclusion: a rule based on the model alone can stay silent for a whole cycle. Why the tops keep getting closer to the trend is shown in the four-year cycle, comparing all cycles. So combine it with trigger 1 or 2. The model tells you when a sale is especially favorable. Your goal and your share tell you when it is necessary.

How much you sell each time

Small parts have an advantage that matters more than perfect timing: you are never completely wrong.

If the price keeps rising, you have kept almost everything. If it falls, you have locked in part at a high price. Both outcomes are bearable, and that is exactly why you stick to the rule.

Two amount rules have proven themselves:

• Fixed steps: 5% of your holding per trigger, at most 20 to 25% per cycle.
• A selling ladder in euros or francs: the higher the price, the more you sell. For example 0.02 BTC at €150’000, 0.03 BTC at €200’000, 0.05 BTC at €250’000. You enter the steps as limit orders at your exchange, so you don't have to decide anything in the moment.

If you sell, sell calmly: on a fixed date, with an order set in advance. If you watch the price every day and wait for the last percent, you are trading on feelings again.

What you never sell

The core holding is the part of your bitcoin that no trigger can touch. It protects you from the most common mistake after a partial sale: the feeling of having got out. As long as the core holding remains, you are still a bitcoin holder.

Just as important are the sales your rule rules out:

• Don't sell below the floor, except in an emergency. The floor is at 42 % of the Power Law line. A year after a day in the floor zone, the price has so far been higher on 100 % of the days.
• Don't sell out of a price slide. A decline is not a trigger and doesn't belong in the rule.
• No new rule at the top. You change your plan once a year, not in the week the price hits an all-time high.

Why that last point is so hard is explained in HODL psychology: coping with volatility.

Taxes: which bitcoin you sell

A partial sale is a sale, and it can cost tax. The situation in 2026 in brief:

• Germany: Bitcoin you have held for more than a year can be sold tax-free. Below that, your personal income tax rate applies, provided all your private gains for the year reach €1’000. The oldest bitcoin in the same wallet or exchange account are treated as sold first. So keep a wallet of bitcoin older than a year ready and sell only from there. More in Bitcoin taxes in Germany.
• Austria: Gains on bitcoin bought from Mar 1, 2021 are taxed at 27.5%, no matter how long you hold. Bitcoin you bought before that and have held for more than a year can be sold tax-free. The proceeds of your selling ladder are therefore smaller, net, by up to 27.5% of the gain.
• Switzerland: Price gains on private assets are usually tax-free. If you trade very often, buy on credit or get a large share of your income from price gains, you can be classed as a professional trader. A few partial sales per cycle are far from that.

Your rule in five steps

1. Set your goal and core holding: What are you selling for, and what always stays?
2. Choose triggers: goal reached, share too high, price above the top band, or two of them combined.
3. Set the amount: a percentage per step and a cap per cycle, or a ladder with prices in euros or francs.
4. Decide the use: an expense, a buffer or a buy-back, and if a buy-back, at what price.
5. Write it down and share it: On My Goal you enter your holding, goal and selling rules and print them as a poster. If you hold together with a partner, set the rule together, as described in How to talk to your partner and family about bitcoin.

If you sell regularly because you live off your bitcoin, different rules apply: then it's about steady withdrawals, not profits at the top. That is covered in Withdrawal strategies: the 4% rule with bitcoin.

Run the numbers on selling and buying back

Many holders sell at the top in order to buy back cheaper later. The calculator "Sell the top, buy back at the floor" shows how much bitcoin you have afterwards and from which buy-back price the sale no longer pays. With no input, it sells at today's top band and buys back at the floor in one year. You set fee and tax under "More settings".

The calculator also shows the risk: if the price never falls to your buy-back price, you end up with less bitcoin and some cash instead. If you want to buy back, you need a rule for that too, or at the bottom you will wait for an even lower bottom.
