I think as there continues to be ongoing education, there will be increased competencies and best practises for self-custoding your Bitcoin. 

The whole Bitcoin experience is a paradigm shift and requires learning the technology. From learning what a hot and cold wallet is. Running a node or not, UTXO management, it can be a lot for people entering the space. 

Though, I find once people go down the rabbit hole, they will became incentivized to explore better ways to secure their Bitcoin. For they will have come to the "true realization" that they are holding the most scarced asset in the world. 👊
