Just a word of advice, a lot of believers like that across US ETF, bitcoin, or even now UT (??)..
The reality is future is not guaranteed despite how many believers talk the same thing. You might wait forever (within your lifetime) and the price never went back, although the chance is very very low. But the chance getting higher if you doesn't have much time to wait (getting older, need to spend for house or kids, accidental and emergency expense, lose job forced retired etc).
US etf was once lagged since subprime mortgage crisis till the rise of Apple / smartphone. That's around 10 years.
Bitcoin was lagged since 2017 till 2020. 3 years. But it is still new, if you compare Gold which similar to bitcoin as store of value, I think previously rise for 10 to 20 years, which at that point everyone also talk about buy gold, then drop and lagged for like 10 years.
For UT, Malaysia market once having the longest bull market in the world, like 12 years, until now soon longest bear in the world. You may find a lot of stories in public mutual thread since they serve the longest business in UT, how many people doesn't make money after 10 years.
Just for anyone to reference, since everyone was talk about how much they made in various investments easily, and recently, but never zoom out.
