In my opinion decentralized exchanges are much more popular amongst trader then centralized exchange because no one can control over them. Deposit and withdrawal are instant. Main thing is using this platforms traders fund are safe. people hold their private key or memonic to use these exchanges.
No. I still prefer trading on centralized exchanges. Unlike you have mentioned, the decentralized exchanges are not fully operating in decentralized manner and operators still have control over our funds. I agree that deposit and withdraw are instant but there is no proven facts to assume about the security of our funds to be safer because we have seen lots of hacking happen in decentralized exchanges as well.
DEX exchange sites have no access to users funds, private keys and the trading activities are done on the Ethereum blockchain while the exchange site works just like Escrow services between the buyer/seller.
You're sounding like P2P kind of transactions are happening in decentralized exchanges but actually the seller/buyer needs to transfer the funds to exchange's addy before the happening of execution of orders. It means the decentralized exchanges will take over the control of our funds before the actual business to be happening. I agree this is kind of escrow services but this is how centralized exchanges are working for years.
in my point of view decentralized exchanges are best improvement in Cryptocurrencies world
Decentralized exchanges are invention after dapps. If there is no such platform like ethereum for providing smart contract things, then we cannot think about having decentralized exchanges.
