I’m about to do either the smartest or dumbest thing in my life.

I’m 22 and I’ve been in crypto since 2021 but only recently my mindset about Bitcoin has really changed. Long story short, I was thinking of investing 15% of my salary into ETFs for the next 20/30 years and not touch that money. But recently I’ve changed my mind and I’m thinking of buying BTC instead of ETFs for the next 20/30 years. This is a very long term plan for me, I do not mind 50-80% volatility swings in the upcoming years.
