>So I'll keep investing in good, underhyped and stable companies and try to weather whatever storm, good or bad, will come in the next years.

This is the obvious strategy, reduce your risk tolerance and go with proven companies. Put your money (fresh from your bank account, not from your portfolio) into moonshots when you can afford to lose them, after that put the moonshot money back into your boring but relatively safe investments. There are low volatility or stable dividends ETFs that specialize in this.
