Reallocation - need your opinion

Hello everyone,

I am 20 years old, currently have a custody account of around CHF 37,000 with IBKR and save around CHF 600 per month.

My current statement:

• ETFs: $IWDA (-0,16 %) (MSCI World), $IUIT (+1,45 %) (S&P 500 IT), $IGLN (+0,84 %) (Gold)
• Individual stocks: $NVDA (-0,69 %) , $GOOGL (-0,84 %) , $BRK.B (-0,48 %) $IBKR, $RHM (-0,22 %)
• 
  Cash: almost nothing

Considering:

• Selling some SWDA and also reducing some gold.
• With the capital freed up, invest more in S&P 500 / Nasdaq or in individual stocks ($MSFT (-0,69 %) , $META (+0,27 %) , $AMZN (-1,15 %) , $NOVO B (-2,59 %) ).
• Possibly also $BTC (-2,7 %) slightly for more "risk-on".

My thoughts:

• MSCI World is too broad and too heavy in Europe/Japan for me, I see more long term return in the S&P 500.
• Gold is okay for safety, but maybe I don't need 10% at 20 years.
• I want more growth / oomph, I am also prepared to endure short-term fluctuations.

👉 Questions for you:

• Would you cut SWDA and weight S&P 500 / Nasdaq more instead?
• Reduce gold and increase tech or EM instead?
• Is it worth adding to Bitcoin or growth stocks like Novo Nordisk at my age in order to achieve even higher returns in the long term?
• Or would it be better to leave everything as it is and just optimize via the savings rate?

Thank you for your feedback 🚀
