no, forget decentralized, we need more people to get into crypto, that means exchanges with more methods to get money into them like: direct deposit, PayPal deposits, credit card deposits, all those are not possible on a decentralized exchange.
btw, if your interested in a big exchange being built and getting in early at a low price, check out Bitfineon it's being built by teh ALQO team and will be ready soon. Get in with them by buying some XLQ on crypto-bridge (a decentralized exchange :)
