Why I believe DEX has an advantage over CEX.
At first glance, everything is obvious for DEX: it has a distributed ledger in open access, unlike CEX, where transaction data is often not always available to the users themselves. Even when working through brokers and tax agents, it can be very difficult to do this and you encounter misunderstandings.
Perhaps it's true that all the shortcomings of CEX need to be brought to everyone's attention to see all the advantages of DEX.
