Hi,
You guys understand Uniswap?
Nothing to hard while trading with Uniswap but the only I mostly encounter while using it is the much fee involved.
That's the disadvantage of the dex and swap service. These kind of services relying on the blockchain. Any transactions that already done through those service will always be broadcasted to the network.
When you are using CEX and it will only show your balance and you can do something with your balance without feel worried to get a big fees for any txs.
This is the different between cex and dex.
