Sensibility is similar to beauty in that it is in the eye of the beholder.
For most people and certainly most normies, I'd say their risk tolerance is going to be relatively low. By having a low risk tolerance you are minimizing your chance of failure but you are also proportionally limiting your chances of success. It is the very definition of median. And in a world where a few rich people have more wealth than the majority of the world and rampant fiat value debasement, even the median is guaranteed to fall well below average.
This is a major reason why most cannot succeed. If one is always taking a low risk approach to life how can they reasonably expect the outcome to be above average?
In this world, if you take no risks you are guaranteeing your wealth to fall below median and on a generational timescale, eventually approach zero.
By putting all your eggs in the bitcoin basket, the risk reward is skewed unbelievably in the favorable side. With that lens, anything but all-in strategy on bitcoin is sub optimal risk management.
