According to https://coinmarketcap.com/rankings/exchanges/

Take this with a large grain of salt, but possibly about 1/3 the size of coinbase and nearly 1/15 the size of binance by volume.

Using https://etherscan.io/gastracker#gassender to see who spends the most gas in ether (not the best metric but it's something) they're somewhere in the realm of a quarter the gas spending compared to binance and coinbase in the last 24 hours.

IMO - they're relatively tiny. They are not a common name in the crypto space outside of their aggressive marketing, and only recently have people really talked about them at all (in the crypto space).

They are not well established in the crypto space, I think they're going for a brute-force marketing approach to force their way in.
