Hmm, a pretty interesting topic.
Convincing a family who have never seen such technology as Bitcoin in terms of currency or technology is very difficult, so it is very difficult to convince them. In fact, the older ones support the younger ones in the work that they know or have experienced. Despite the worrisome concept of Bitcoin, it is no less than miraculous for these people of the old generation, so therefore, according to my estimation, our mother or family is not ready to invest in Bitcoin, but they feel fear of investing in it.
So I personally think that this is one of the reasons why most of our families are not in favor of adopting Bitcoin. But anyway, it means to say that on this topic, we should encourage our families, etc., that Bitcoin is a good thing and needs to be adopted.
