I cant help but agree with you a little. I'm probably in the same category as the people you mentioned though. I am living off of about 200 a month and spending the rest of my income on Bitcoin. but does that really make me greedy, or does that make me smart? I guess we will find out sooner or later, hopefully later. But now that i think of it, looking at the people I've managed to coerce into using bitcoin, most of them think of it only as a way to make some money. But I dont expect them to fully understand how bitcoin works, or what it could do for the world. For now, It's good enough that they are simply using it. Lets put it this way... don't you think its better to have some non tech savvy people using bitcoin for their personal gains than none at all? I mean if they can find some use in it, then good for them. All in all, I think more users is a healthy thing, whether they use it for greed or for whatever else it is that floats their boats. I do my best to teach them as much as i can about bitcoin, but many of them just dont have the capacity to really understand, but I think a broader understanding will come with time.
This is what annoys me. People put money into Bitcoin simply on the idea that it's a good idea cause it's going to make them more money down the road. This whole idealism will be the death of Bitcoin.
You are not supposed to make fiat money off bitcoin, the whole point is bitcoin is supposed to replace fiat.
