That's certainly true, mate. Unfortunately, the mindset of many people within crypto is to get rich quick. They're don't care about how useful the technology is for the real world. Either centralized or decentralized, people tend to join the next big thing in crypto. Some projects have even claimed to be decentralized, when theoretically they're not (like EOS and Ripple). Which is why, it's important to research various cryptocurrencies in order to determine which ones are decentralized and which are not. The wide misconception of decentralization, has caused many to abuse its power. Scammers, hackers, and other malicious actors have been rampant in this field more than in the centralized realm.
However, knowing that decentralization brings us freedom, should gives us a sense of being more responsible than never before. In the end, it's just a matter of choice, whenever people remain in the centralized realm (where Banks, governments, and big corporations are dominant) or switch to full decentralization altogether. Just my thoughts
