If they have resources in the first place, they can always run their promotional campaigns. Because venturing in the crypto exchange business is not a small deal. You should have good bankroll to begin with, unless, you want to run like a fly-by-night exchange.

They're not an exchange, as the thread title itself said. They're an aggregator. Think of a CMC or coingecko "market" section where you can see a lot of available bid/ask price for the token you want to sell/buy. Next, think of a PCS where the exchanges happen between you and the seller, and PCS only act as a platform to connect you both. That's where alligator sat.
