No, a crypto exchange, like any other exchange, is a platform to connect buyers and sellers. However, if there are few buyers or sellers for your token, there is nothing an exchange can do. Market makers play the role of buyers and sellers. To put it into perspective, up to 50–60% of U.S. equity trading volume comes from high-frequency trading market makers, so that any investor can buy and sell any equity at any time.
Most exchanges in both traditional and crypto markets rely on market makers to provide liquidity on their platforms. Exchanges consider market makers as important customers as retail and institutional traders and create specific market making programs to attract and cater to liquidity providers.
Crypto exchanges are becoming more and more similar to traditional exchanges every day. Most top tier exchanges now require projects to have market makers as a condition for getting listed. Don’t test your luck trying to get listed without getting an advice from a professional market maker first.
Ask your targeted exchange to introduce you to 2-3 best crypto market makers! Professional exchanges (e.g., Coinbase, Kraken) would be your best advisors in this respect.
