I am waiting when the liquidity of DEX will increase and many people will start to use them. Because I am for anonimity. And DEX are more secure.
Well, strictly speaking, DEX does not provide anonymity. All transactions are recorded in the blockchain. If you wish, you can track a deposit on the exchange, a deal, a withdrawal from the exchange. In some DEX, it is not always possible to link deposit and withdraw addresses. Sometimes this may provide some anonymity.
For anonymity, anonymous coins should be used if they are supported by DEX. Unfortunately, I do not know such a DEX.
That is why Bitcoin mixer is necessary to have the full anonymity. Bitcoin mixer mix the transactions. But it is very important that the user will receive transactions with good history.
