The guy behind BearBullRadar
Dominic Tschan. MSc Physics, ETH Zurich. Crypto investor, bot builder, physics teacher. Three kids, one wife. One rule: don't believe anyone until you've tested it yourself.
How it all started
2020. Covid. Lockdown. Like many, I started getting into Bitcoin.
Not out of boredom. Out of curiosity.
I studied physics at ETH Zurich. When something interests me, I want to UNDERSTAND it. Not just the surface. 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."
Then I started doing the math.
Not "I think this works." Real Bitcoin data. Six years. Every strategy systematically calculated. Like in physics: form a hypothesis, test it, analyze.
Not once. Hundreds of times.
The moment it clicked
Over 200 strategies tested.
Most were garbage.
RSI. Bollinger Bands. Fear & Greed. MA crossovers. Breakout systems. Almost everything failed on real data. The five that made it through my filter had one thing in common: they were boring.
The 5 that survived
Few trades. Parameter-robust. Positive in every time window.
None of them looked impressive on Twitter. But they worked.
So I automated them. Those five became the backbone of what you see today. Over time, five more experimental strategies earned their way into paper-tracking.
Today: ten live bots. One on real money. Nine paper-tracked. Every signal visible in real time. Every tier honestly labeled.
Why I'm sharing this
I learned some expensive lessons along the way.
$178,000 on the screen and I didn't sell.
Three years patiently buying XRP that I'd decided, on paper, was dead money.
FOMO. Panic. Sleepless nights.
Been through all of it.
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.
Six years, one timeline
Education
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. Five survived.
2024 – 2025
First live bots deployed
The Watchdog on real capital (BTC cycle filter, still the most-tested of the bunch). Das Genie on DeFi governance. The Scout on breakouts. Each one built because the math cleared its own bar.
2025
$178,000 on the screen, the lesson of my life
A memecoin, 60x gain, didn't sell. Portfolio from $180k back down to $40k. After that I knew: I need a system without emotions. The bots were the response.
April 2026

ExploreMy philosophy
No hype. No "Bitcoin to 1 million." No affiliate garbage.

Data over gut feeling.
Always.
