That is the thing, they do not care about the real purpose of bitcoin they only care about one thing and that is to make money and as long as that is the case those people are never going to become holders as for them there is not really any need to do so, they think of bitcoin as nothing more but a way to make some easy money and the moment that is not the case then they leave the market, I do not blame them however very few people can make money doing something like this which is why we see so many stories of people losing everything they invested in just a few months.
Isn't Bitcoin created for transactions since it was made to function as a currency? So why are you so concern about people not holding Bitcoin since Bitcoin purpose is not holding it but rather transact with it. And, isn't holding Bitcoin's aim is to make money through price increase, holding Bitcoin doesn't sounds any different than having a goal to make money?
