I did some research on Bitcoin because I was interested in it, and I discovered that the key principles of Bitcoin are peer-to-peer, anonymity, pseudonymity, decentralization, and operating without a middleman to ensure that Bitcoiners can have financial freedom. However, despite knowing that Bitcoiners adhere to these tenets, why do some Bitcoiners act contrary to them? Why do they continue to support centralized exchanges, use them, and retain their Bitcoin there?
Because, lets face it, there are way too many people that came from the idea to do some "investment" and even worse from a "get rich quick" mindset. And not from a "oh, what an incredible technology, let me explore this thing that will change the way our financial-world works" point-of-view.
I'd go as far and say 80%+ of people holding Bitcoin have no idea what it really is and what its core values/strengths are.
If you keep that in mind, it won't suprise you that still the majority doesn't care about using a centralized exchange service - to the contrary even: These folks may feel that with a company owning an exchange instead of a peice of software that allows p2p exchange (such as Bisq for example) there is someone that can be held accountable if things go wrong. Ofc that's wishful thinking but that's how things have been for ages and the only thing they know.
