About Me
The guy behind BearBullRadar

Dominic Tschan
MSc Physics, ETH Zurich
Physics teacher · Crypto investor · Bot builder · Switzerland
I'm Dominic. I studied physics at ETH Zurich and today I teach physics and math. I live with my wife and our three kids in Switzerland. And I don't believe anyone until I've tested it myself.
How it all started
2020. Covid. Lockdown. Like many, I started getting into Bitcoin. Not out of boredom, but curiosity. I studied physics at ETH Zurich. When something interests me, I want to UNDERSTAND it. Not just the surface. But the mechanics underneath. Hypothesis, experiment, analysis. That's what ETH taught me. And that's exactly how I approached crypto.
So I did what everyone does: watched YouTube, read Reddit, followed trading "tips". RSI. MACD. Fear & Greed. "Buy the dip, bro."
And then I started doing the math.
Not "I think this works". But: real Bitcoin data. 6 years. Every strategy systematically calculated. Like in physics: form a hypothesis, test it, analyze. Not once. Hundreds of times.
200 strategies tested. 195 were garbage.
RSI, Bollinger Bands, Fear & Greed, Moving Average Crossovers, breakout systems — almost everything failed on real data.
The 5 that survived
5 strategies survived my filtering process. They all had something in common: they were boring. Few trades. Broad parameter robustness. Positive results in EVERY time window.
None of them looked impressive on Twitter. But they worked. So I automated them. That became 3 trading bots that now run live with real money.
Why I'm sharing this
I learned some expensive lessons along the way. $178,000 on the screen and didn't sell. 3 years patiently buying XRP. FOMO, panic, sleepless nights — been through it all.
BearBullRadar is my attempt to make the crypto world a little more honest. For my father-in-law who asks "Should I buy Bitcoin?" For the colleague who read "Buy the Dip." For everyone who wonders what REALLY works.
Every article is based on real data. Every claim is backed by numbers. I share my mistakes just as openly as my successes.
My Journey
Career
MSc Physics, ETH Zurich → Physics & Math teacher
Physics degree from ETH Zurich. Today I teach physics and math. I explain things so everyone can understand. Preferably with visuals and examples instead of formulas.
2020–2024
200+ strategies systematically tested
Walk-forward analysis, parameter sweeps, out-of-sample tests. Every strategy on 6 years of real Bitcoin data. 195 rejected.
2024–2026
4 trading bots built
The Watchdog (BTC cycle filter), The Scout (breakout finder), The Genius (DeFi scanner), and The Alpha Hunter (US stock momentum). All four running live.
2025
$178,000 — and the lesson of my life
A memecoin, 60x gain, didn't sell. Portfolio from $180k to $40k. After that I knew: I need a system without emotions.
2026
BearBullRadar launched
Everything I've learned, in one place. Articles, calculators, bots, radar. For normal people, not Wall Street junkies.
Today
Family, 5 bots, 0 sleep issues
The bots trade. I sleep. Morning: check Telegram, have coffee with my wife, make breakfast for the kids. That's how it should be.
