Psychology & discipline: how not to get in your own way

Bitcoin’s price swings hard, and around the clock. That tempts you to act on feelings instead of a plan – and it costs many investors money.

Why Bitcoin tests your nerves

According to an analysis by the Bank for International Settlements (BIS), between August 2015 and December 2022 the majority of crypto-app users in almost all the countries studied lost money on their bitcoin. After the collapses of Terra/Luna and FTX, large, experienced investors sold while small retail investors bought.^[1] Yet at the end of 2022 the price was more than 50 times higher than in August 2015.^[2] So the losses came mainly from when people bought.

Staying calm is particularly hard with Bitcoin. VolatilityGlossaryVolatilityA measure of how strongly a price fluctuates, usually given as annualised standard deviation in per cent. Bitcoin fluctuates much more than a broad stock index or gold – up and down.On the learning path: Stage 3 · Step 3 – Returns & risk →In the glossary →× is high: from January 2014 to August 2026, the price rose by 30% or more in 19 of 152 months and fell by 30% or more in 6 – most sharply in June 2022, by around −37% (monthly closing prices in US dollars, own analysis).^[2] There’s no market close, and both euphoria and doom reach you unfiltered on your phone.

FOMO: the fear of missing out

Psychologists describe FOMOGlossaryFOMO (fear of missing out)‘Fear of missing out’. With Bitcoin, it’s the urge to buy quickly after sharp price rises. FOMO is a common trigger for costly bad decisions.On the learning path: Stage 3 · Step 2 – Goal first →In the glossary →× (fear of missing out) as a persistent worry that others are having rewarding experiences you’re not part of.^[3] With investing, that means: the price rises, friends talk about their gains, and you feel left behind.

Germany’s financial regulator BaFin urges finfluencers not to use psychological tricks and not to make their followers afraid of missing out.^[4] Fraudsters exploit exactly this feeling, for example with ‘exclusive’ chat groups or ‘today only’ offers – more in Spotting & avoiding scams.

How to recognise FOMO:

• You want to buy because the price has just risen sharply – not because your plan says so.
• You spontaneously raise the amount or dip into your emergency fund.
• You feel time pressure: ‘If I don’t get in now, it’ll be too late.’

What helps: the reverse question. Would you buy the same way if the price had fallen by 30% over the past month? If not, your feelings are deciding – so wait at least 24 hours. An automatic savings plan takes the timing question off your hands entirely.

Panic and loss aversion

The counterpart to FOMO is panic in a crash. Behind it lies loss aversion: losses weigh more heavily on us than gains of the same size. Daniel Kahneman and Amos Tversky described it in 1979 in their prospect theory.^[5] They later estimated that a loss weighs about 2.25 times as much as an equal gain.^[6] Put simply: a $1,000 loss weighs about as much as a $2,250 gain.

Bitcoin has fallen more than 50% from its high several times (drawdownsGlossaryDrawdown (decline from the peak)The decline of a price from its last peak to the following low, as a percentage. Bitcoin has fallen by more than 75% several times; from October 2025 to June 2026, it fell by around 53% (in US dollars).On the learning path: Stage 3 · Step 3 – Returns & risk →In the glossary →×). Most recently, the price fell by around 53% between 6 October 2025 and 30 June 2026, from $124,728 to $58,526 (daily closing prices).^[2] In phases like these, loss aversion pushes you to ‘save what’s left’. Selling then turns a fluctuation into a permanent loss. What holding on has meant historically is shown in Holding for the long term.

Dive deeperThe flip side: selling winners too early, holding losers too long

In 1985, Hersh Shefrin and Meir Statman described investors’ tendency to sell winners too early and hold on to losers too long.^[7] With Bitcoin: after a 20% rise, people ‘lock in the gain’ even though the plan runs for ten years. After a 60% fall, they sit tight ‘until the purchase price is reached again’ – even if the reason for buying no longer holds.

If you want to invest a larger sum and cope badly with losses, you can phase your entry. What that costs and what it brings is covered in Savings plan or lump sum?.

Confirmation bias: we find what we’re looking for

Confirmation bias is the tendency to seek out and interpret information so that it fits your own opinion.^[8] Convinced Bitcoiners mainly follow voices that expect rising prices; sceptics mainly read obituaries. Social networks reinforce this by showing you more of what you’ve already clicked on.

The result: legitimate warnings about costs, custody or fraud get dismissed as FUDGlossaryFUD (fear, uncertainty and doubt)Short for ‘fear, uncertainty and doubt’. It refers to news that stirs up sentiment against Bitcoin. Not every criticism is FUD – some warnings are justified.On the learning path: Stage 2 · Step 3 – Criticism & risks →In the glossary →× (mere scaremongering), and the position grows larger than the plan allows.

What helps:

• Read the counter-arguments: once a year, the strongest objections, for example in Criticism & risks. You don’t have to agree with them, but you should be able to explain them.
• Look-back exercise: suppose your Bitcoin decision turns out to be a mistake five years from now – name three possible reasons and guard today against whatever you can.
• Check for yourself: DYORGlossaryDYOR (Do Your Own Research)Short for ‘Do Your Own Research’: check information yourself instead of blindly following tips. Meant seriously, it’s good advice – tacked onto promotions for dubious projects, it’s often just a phrase that shifts responsibility.On the learning path: Stage 6 · Step 2 – Spotting scams →In the glossary →× (‘do your own research’) means reading primary sources and dated figures, not watching yet another video.

Information diet: less price, more clarity

The more often you look, the more often you see a loss – and the riskier the investment feels. Shlomo Benartzi and Richard Thaler called this ‘myopic loss aversion’.^[9] With Bitcoin, it looks like this:

How often you look	How often the price was down
every month (monthly close vs. previous month, 01/2014–08/2026)	70 of 152 months (46%)
once a year (calendar years 2014–2025)	4 of 12 years
one year after buying on any day since 2013	around 31% of cases
three years after buying on any day since 2013	under 1% of cases

Own analysis based on daily closing prices in US dollars.^[2] The past is not a forecast: a purchase on 16 December 2017 was still around 13% down even after five years.^[2] Checking daily mainly delivers noise – and occasions for decisions you would otherwise never have made.

What an information diet looks like:

1. Switch off price push notifications and take the price app off your home screen.
2. Fixed dates: for example, once a month on the day your savings plan runs, and in detail once a year when you review your plan.
3. Sort your sources: prefer sources that give figures with a date and origin. Avoid channels that sell price targets, ‘signals’ or urgency.
4. Leave chat groups about quick profits. That’s where FOMO, confirmation bias and fraud meet.

If-then rules that kick in at the right moment

Good intentions are rarely enough. Concrete plans of the form ‘if X happens, then I’ll do Y’ work better. The psychologist Peter Gollwitzer showed that intentions like these, formed in advance, lead to the goal considerably more often than general intentions.^[10] For Bitcoin, they could look like this (examples, not recommendations):

• If the price falls by 30% within a month, then I change nothing about my savings plan and read my journal entry from when I bought.
• If I want to buy or sell outside my plan, then I wait 24 hours and write down the reason.
• If someone pushes me to make a quick decision, then I say no – without exception.
• If my Bitcoin share rises above the upper limit I set, then I bring it back to target on the next scheduled date (rebalancingGlossaryRebalancingBringing your asset allocation back to its planned shares. If the bitcoin share has risen sharply, you sell some; if it has fallen, you top up. This keeps your risk within the limits you set yourself.On the learning path: Stage 3 · Step 3 – Returns & risk →In the glossary →×).

You’ll find a complete plan with target share, savings amount and review date in Holding for the long term, and how to set a share in Bitcoin as a small portfolio allocation.

The investment journal

An investment journal records what you decided, why and in what mood. Later you can see whether your plan or your feelings made the decision – memory tends to be flattering.

This is what it could look like (made-up entries, example price):

Date	What	Amount and price	Why	Mood (1–5)	In the plan?
2 Mar	Savings plan purchase	$50 at $80,000/BTC	monthly instalment	1	yes
18 Mar	Considered an extra purchase, didn’t do it	–	saw a video with a price target	4	no, waited 24 hours
30 Jun	Price 50% below the high, did nothing	–	plan says: instalments keep running	4	yes
2 Jan	Annual check	share 3.4%	target 3%, range 2–4.5%: no action needed	2	yes

1. One line for every decision

   With reason and trigger: the plan, a price move, a news item or a conversation? Purchases or sales you held back from count too.

2. Rate your mood honestly

   From 1 (calm) to 5 (very agitated). Decisions at 4 or 5 deserve particular scepticism.

3. Look back once a quarter

   Where did your feelings win? Every pattern can become a new if-then rule.

A record with date, amount and price also helps with your taxes – though tax authorities generally want the values in your national currency (the German tax office, for example, in euros). What belongs in it is covered in Record-keeping & tax tools.
