There is always a way out for everything and there is always a solution to every problem.
Creating a world exchange sites for cryptocurrency with real identity like binance will centralised and decentralized organization.
There are sometimes that binance do have control of your wallet and can seize your withdrawal at anytime they want that's the disadvantage of centralised Organization with third party.
The only thing that can be done to avoid fraud in this decentralized platform pob community is that there should be real identity attached verified to every wallet as @iyiade said.
I love that idea it's a great one.
Attachment of real identity to a wallet does not mean it's centralised or does not mean they have control over any people's asset, do they won't be able to stop anyone transaction or take out of the person asset or take charges do you let in the just have to do is just attached identity so anyone who want to open a crypto wallet we'll have to open it with his real identity and that will not stop him from opening multiple wallet but his identity must just be attached to it and his phone number details and so on.
That can be done by creating another system and attach it to the block chain.

You are right
Creating another body add attachment to the blockchain technology will do that better.
It will make a cryptocurrency decentralized with full of security without being centralised and if an illegal transaction take place it won't be stopped but it will be traced to the person who Transact illegally or for illegal business
