Yes you are right, there are people who don't sweat to make good investment or becoming successful in life because they are intelligent and they get results through their smartness.
And of course investments today need smartness to avoid loses and most people who do incur loses in their investments or trading is as a result of not becoming smart enough.
When they already know what to do then any investment will not scare them, as long as there are boundaries that they do not have to break. Having intelligence when it comes to investing and trading also requires considerable experience, so know how the crypto market works.
People who claim to be smart and look skilled at trading and investing may not necessarily be able to keep what they stand for,
this is only because of untrained psychology and only thinking about a profit without losing.
Fear and greed are traits that exist in every human being, only at different levels,
if they can control them then there are more opportunities to produce a goal that will produce good profits.
