What other factors can propel a CEX growth?
I think one of the biggest factors is how strict they are when it comes to KYC enforcement. Exchanges mostly grow big if the KYC requirements are relaxed. Remember Bitmex before KYC. It was so huge!
Once Bitmex started mandatory KYC verification, most of the derivatives trading volumes moved to Bybit as so on
I don't know much about Bitget's KYC requirements, but I believe it's one of the reasons the exchange has grown exponentially.
I think wih mandatory KYC common accros most top exchanges; easy process of getting kyced should be another factor as pointed out but I still feel early listing of potential project has been an obvious reason for growth particularly if you closely monitor Bitget. Their spot trading volume saw more than 200% increase from Feb - March in the Coingecko Q1 report. They have recently been on the spotlight for early listing and users are more inclined to platforms that provide profit opportunities.
