When it comes to money, there is something valuable in regards to the non-physicality.. but at the same time, the non-physicality of the value of bitcoin has been secured in decentralized ways that make it verifiable and there are no copies of it, even though it can be divided into smaller or larger units.
Sure there can be times in which physicality is preferred, but if a guy has a few million in value, he is going to have easier times to hold it, conceal it and move it around when it is in bitcoin as compared with if that same value were in gold (physical or some paper representation) or dollars (or other fiat whether physical or held by a third party). There can be difficulties with the larger amounts, yet there are also some potential inconveniences with smaller amounts too.
Bitcoin is not without some challenges and even some technical questions regarding various ways to access the bitcoin or to guard it or to guard its back ups so that someone might not be able to take it when mistakes are made.
You clearly explained that Bitcoin non physical nature is major strength because its value is securely tracked and can not be copied making it much easier to hold and hide and move large sums of money compared to physical gold or traditional bank funds. Even though Bitcoin has clear benefits like being easy to move and store it also has some tricky parts. Means that is right that users need to be very careful about how they get to their Bitcoin and how they keep it safe and how they make copies of their access information because small mistakes can lead to losing their money.
