Has anyone here tested a 3 pillar long-term portfolio (stocks + crypto + gold)?

Not financial advice.
I’m studying how different assets behave across full market cycles, and I keep seeing that stocks, crypto and gold respond to completely different types of macro conditions.
Curious if anyone here has actually tested a long-term mixed approach like:

• Index ETFs (VOO/VTI)
• A small BTC/ETH allocation
• Gold or GLD as a stabilizer

Did it feel different behaviorally compared to being 100 percent in one asset class?
