Binance remains the top centralized exchange, just like it has been over the years, it's the most popular among the known exchanges, whether it's CEX or DEX. Despite the issues that it's owner and former CEO CZ, is facing with the US authorities that prompted the appointment of a new CEO, people speculated that it might affect the reputation of the exchange, but clearly that is not the case now, and so far the new CEO mr. Teng, is working hard to maintain the trust that people have about the exchange, I don't see them shifting ground from the number one position. As for decentralized exchanges, I don't use them, so it's no wonder that I've not heard about ORCA, before, congratulations to them for hitting the number one in DEX.
