Binance is growing thanks to the hard work of CZ and the aggressiveness of developing that he has, with all the initiatives that we see from Binance, initiatives like Academy, Info, Labs, Launchpad, Research, Trust Wallet, etc... and more. CZ accomplished this by launching the exchange at the right time and thanks to good management.
Will we see other exchanges doing something of this magnitude someday? We don't know, we are still at the beginning of the crypto industry, the possibility is there.
