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.
It is these advantages that make people can trust bitcoin easily and today we have not determined any other form of investment that is more perfect than bitcoin, despite the magnitude of the risks posed by its price fluctuations.
What most people expect from an investment that is run, decentralization and freedom and these two things are the basic considerations that make people make decisions in bitcoin.
However, despite knowing that Bitcoiners adhere to these tenets, why do some Bitcoiners act contrary to them?
Utilization will decide something according to its use, there are many reasons why people still act outside of conflicting principles as you mentioned.
Why do they continue to support centralized exchanges, use them, and retain their Bitcoin there?
Some people still use centralized exchanges for transactions made in bitcoin, but that doesn't mean they don't understand the principles of bitcoin and there are still many people who currently store bitcoin in wallets that are much more secure and not everyone stores bitcoin in centralized exchanges. Centralized exchanges are only used when they are trying to make transactions, whether small amounts or larger amounts.
While in my case it's possible to use a centralized exchange only when I want to make a transaction, the exchange I use is usually licensed to operate in the country where I live, but I don't hold bitcoins on a centralized exchange either in the short or long term.
