Coinbase doesn't need to care about the value of crypto, it makes money on fees when people buy or sell against USD. All it should care about is the traded volumes, and they don't necessarily have to be a lot lower in a bear market.
We’re not even in a proper bear market and its already collapsing
Just see dex trading volume metrics or OpenSea volume data on Dune.com - a much better indicator of the state of the crypto markets since you can’t hide on chain data
Coinbase ran a gambling business like an exchange business. That's their mistake. The guys who knew they were running unregulated slot machines are doing fine.
