The first thing one has to do when analysing past money decisions is to judge the decision based on the information available at the time.
I too watched from the sidelines as btc, nvda and others went to the moon. But with the information available at the time, investing in those was not a sound strategy.
Survivor bias again - these are the few that made it while many others did not.
It's true.
In my experience, you'll be able to evaluate the correctness of your actions today in about five years, when you have more data and results.
There are plenty of people that thought WeWork would go to the moon, too.
Even if I would've bought Nvidia, Bitcoin, or whatever stock... who is to say I would've had the balls to hold it all the way to whatever they're at today. I probably would've ended up like the guy who spent 10,000 bitcoin on a pizza.
