How to Build Probabilistic Thinking in Crypto

In the world of crypto, nothing is ever truly certain. Prices can soar overnight — or crash just as fast. That's why one of the most powerful tools you can develop as a crypto investor or trader is probabilistic thinking. Unlike binary thinking — where outcomes are considered either a "yes" or "no" — probabilistic thinking allows you to consider multiple outcomes, weigh the risks, and act accordingly.

So, how do we train ourselves to think probabilistically when it comes to investing in crypto?

1. Shift Your Mindset From “Certainty” to “Possibility”

The first step is probably the hardest — shifting your mindset. Most retail investors enter the market thinking, “This coin will go up,” or “Bitcoin has to pump after halving.”

Here’s the truth: nothing is guaranteed in crypto. Even if you’ve done your research, studied on-chain metrics, and analysed the charts, the market can still surprise you. That's why it's crucial to stop thinking in terms of "definitely" and start thinking in terms of "maybe" or "likely."

Admit that you're playing a game of probabilities, not certainties.

2. Build Your Own Bull, Neutral, and Bear Scenarios

Good traders — especially in volatile markets like crypto — don’t just rely on one prediction. They create multiple scenarios to cover different possibilities:

• Bullish case (e.g. 60% chance)

• Bearish case (e.g. 30% chance)

• Sideways market (e.g. 10% chance)

By doing this, you give yourself a structured framework to operate in — rather than reacting emotionally when the market does something unexpected. Once you have your scenarios, you can size your investments based on those probabilities.

3. Estimate Potential Risk and Drawdown for Each Scenario

After creating your market scenarios, the next step is risk sizing. Let’s say:

• In a bullish market, you're willing to risk AUD 1000

• In a bearish scenario, only AUD 500

• In sideways conditions, maybe just AUD 300

Then ask yourself this: Am I truly comfortable losing this amount if things go south? If the answer is no, scale back the amount until it feels acceptable.

The goal is to only risk what you can emotionally and financially afford to lose.

4. Use the Expected Value (EV) Formula

This is where things get more strategic. Probabilistic thinkers often use Expected Value (EV) to determine whether a trade is worth taking. Here’s the formula:

EV = (Probability of Win × Gain) – (Probability of Loss × Loss)

Let’s say you're considering buying a new altcoin, $ABC:

• You believe there’s a 30% chance it will double (100% gain)

• But also a 70% chance it will drop by 50%

Here’s how the EV works:

ini
EV = (0.30 × 100%) – (0.70 × 50%)  
EV = 30% – 35% = -5%

That’s a negative EV — a trade you should probably avoid.

Interpreting EV:

• EV > 30% → Very strong trade opportunity

• EV between 15% to 30% → Worth considering

• EV between -5% to +15% → Neutral or worth testing

• EV between -15% to -5% → Weak

• EV < -15% → High-risk, low-reward (avoid)

This method adds a layer of logic to your trading and helps remove emotional decision-making.

Final Thoughts

Probabilistic thinking isn’t just for mathematicians or quants — it’s a mindset. It’s the same principle poker players use: make the most +EV decisions over and over again, even if individual hands sometimes don’t work out.

In crypto, you’re not aiming to be right every time — you're aiming to be right enough, often enough, to come out ahead in the long run.

So, next time you open your trading app or consider buying into the next hyped coin, take a step back and ask: What are the odds? And more importantly — is it worth the risk?
