On the other hand p2P can be used through CEX and kyc is mandatory for p2P services. Because of these basically we cannot avoid sex.
You may want to rephrase that
Everything has pros and cons. For DEX, we will fully guarantee our privacy
Who is we?
but there will be disadvantages such as high transaction fees and not enough services like CEX provides us. Especially for day traders, DEX does not yet offer a daily trading feature.
Why are you engaged in such a risky thing like day trading? You like losing money?
For those still believing in getting rich over the night I suggest reading this topic:
Trade vs. HODL - avoid traps.
For me, both are good and each person has their own choice depending on their needs. I wouldn't be so stubborn as to say that people who are using CEX are idiots just for the sake of privacy.
Some would also say that smoking is healthy or excessive drinking of alcohol is healthy. That doesn't mean that those activities are healthy. You can say and think whatever you want, that will not make CEXs a good phenomena in crypto space.
p2p services are not available here. So DEX can be used to trade cryptos and CEX to cash them out as needed. Because we don't usually need to cash out large amounts, CEX can be used to cash out small amounts as needed. Or avoiding Cex we can physically sell crypto to known crypto investors. In this case at least we will not have any fear of document theft
See? You already answered yourself about how to avoid CEXs although you don't have DEXs in your are.
You are wrong, most DEXs provide p2p features but because the number of DEX users is still limited, p2p trading will be a bit difficult. For example, it will take us longer to find suitable buyers and sellers, we do not have as many options as in CEX.
This happens because so many users headed to CEXs at the beginning. Time passes and people start to understand the huge risks they are confronted with when using CEXs and DEXs came into play recently. The more people will use DEXs the more DEXs will exist. This is an effort we all have to do in order to avoid this plague caused by CEXs.
One more thing, p2p on centralized exchanges is no longer pure peer-to-peer trading because of exchange intervention. While that ensures the transaction goes smoothly and we can complain if a dispute arises, it makes the transaction no longer truly peer-to-peer.
Peer-to-peer services by CEXs are a joke, as you are also fully exposed to all risks involved by CEXs. Stay away of these services!
By the way, if you use CEX to withdraw or convert to fiat, it means your identity is exposed, it is not necessary for you to use DEX to trade when your identity is known as CEX has be collected.
This is true. Never associate crypto with CEXs and with banks!
