Phising has been a large problem for DEX sites. How binance's dex would be able to solve the phising attacks would be the decisive factor for the success of the said dex. On other matters, we could expect everything better than current dex when it's coming form binance itself.
There is nothing they can do about phishing attacks, they can't prevent someone from placing a fake advertisement on google or a user from clicking a link received in an email. By the way, not only decentralized exchanges have been the target of phishing attackers, but also centralized exchanges and wallets.
A centralized exchange platform can be attacked by a phishing method too. This is not a problem of a DEX. To avoid this vulnerability, a trader should check the SSL/TLS certificate of the network connection. Don't use the site if the verifying is failed and displayed in red or gray.
I bought some BNBs. Although their price are volatile, I think they are a promising ERC20-tokens. It seems that Binance evolves and now looks pretty good.
