There is a lot of young people who think that stocks only ever go up. Wait until the the stock market crashes, and target date funds with it.
Target date funds aren't all stocks specifically to avoid this problem.
"Target date" means the ratio of stocks to bonds in them is getting rebalanced each year - the closer the target date (retirement), more bonds and less stocks. They have 60% or more in stocks.
Okay. BTC can crash too. There is no risk free financial instrument that generates wealth. But index funds are far more stable in the long run.
Many people in the US and elsewhere dont even know what that is. Know whats way easier? Holding a global non-inflatable reserve currency and forgetting the rest of the BS.
