Sadly, we have a lot of people who just want to get rich quick because they've heard about it on mainstream media.
That's pretty normal mass-user behavior. Initially I was pretty much the same. I bought my first coins in very early 2013 as being a noob not knowing anything about Bitcoin. I was solely interested in the returns, and that was basically it. I think it was very early 2015 when I actually started to get interested in Bitcoin's technical aspects rather than just the price, which was also the moment I never ever touched a single altcoin again. The far majority of the altcoins don't serve a single purpose and are just redundant garbage.

For me personally Bitcoin is about outruling goverments and banks, and I am glad that I have more than half of my entire wealth sitting safely in Bitcoin. I wouldn't want it to be any different. It's allowing me to enjoy the financial freedom that I deserve to have, but never had before Bitcoin, and that's what I am thankful for. Other than that, I know the article is a subjective view, but I personally don't care about a better society, because what others are doing is none of my business.
