I think from the perspective of "leverage," the kill line is clear.

American student loans vs. Chinese mortgages.
No one is better or worse than the other.
Both are ordinary civilians caught up in social loans for decades.
Then they realize after paying half that years of repayment are just interest to the bank,
the principal hasn't been paid off at all.
Finally, during an economic downturn, they can't hold on and reach the kill line!

At the same time, the kill line in the crypto circle is far ahead of the global level.
Because these people live closest to leverage—loving and hating it simultaneously.
Love for getting rich overnight, hate for liquidation and zeroing out.
To this day, I haven't seen anyone in the circle who hasn't been "liquidated" by leverage.
So the most common advice elders give to newcomers entering the circle is
"Stay away from leverage"!!
