We can't stop them for only believing that bitcoin is only a way to make profits.
I think we can do what we can to educate them on why the current system is failing, as why a decentralized alternative is so important.
If people really understood the philosophy this tech.. they'd be more psyched about holding and striving for mass adoption so they would never have to convert back to fiat.
Yes we can educate them but we can't stop them if they only sees bitcoin that way.
It's up to them if they will absorb that things that we are about to tell them and its still them to decide whether they will listen or won't.
Not all the people here are for the tech, you have to remember that thing.
