Thanks for pointing this out. My partner and I teach crypto and consider this knowledge to be a top priority. It is unfortunate that most new students are distracted by the ease with which you can buy crypto and therefore don't bother to learn about the crucial facets to being successful in it. Even though we pound the table with all of the examples of how important it is to "understand" and "act" on protecting digital assets, the most common path that leads to learning this information involves making a mistake and either losing your crypto or worse, having it stolen from you.
