I have withdrawn and trade ETH from MEXC multiple times already and I am never charged more than $3 but when I swap ETH ERC 20 on Uniswap the gas fee is almost always $10 and few times over $10, why is it like this? Are DEXs suppose to be more costly normal centralized exchanges?
I used it last and the transaction fee was too high so after successfully transferring the coins from there I left the app and refused to use it again. Normally, though for once I have used the Centralized Exchange transaction fees are cheaper than the Decentralized Exchanges. And that is one the factors that I am not using Decentralized Exchange for any transaction for now. And their prices are lower than CEX.
This is precisely why CEX are more patronized than DEX, because centralized exchanges are more convenient and has cheaper transaction fees for smaller transactions than the decentralized exchanges, as is obvious from the OP unfavorable experience. People are advocating for DEX but with this Uniswap, being a reputable DEX high fees for small transactions it's not helpful, only favorable for big transactions.
