if you don't study enough you need balls of steel.
if you do study enough, you don't need balls of steel as you will have knowledge. knowledge is better than balls of steel.
and as most don't study enough, they don't understand this as they never understand the difference of: with or without knowledge.
a lot of traders tried the balls of steel theory: they stayed in a trade till they got wiped out. but at least they proved they had balls of steel.
I can assure you: In the crypto space you need both! Knowledge to understand what/why is undervalued or not, as well as how this value could be unlocked. Balls of steel to handle the volatility.
