Buy and sell limits prevent using coinbase to trade BTC like a stock unless you're talking extremely low limits or extremely long term (like a retirement fund, which I wouldn't recommend)
So the liquidity is weird, I can turn less than $15K into USD in a few moments, but $15001 will take me two weeks and is scary given volatility. I would argue this intentional as in this is why coinbase isn't very useful for drug money laundering.
I once bought a commemorative Swiss Army knife with Debian Linux branding and spent like $200 on nickel and time fees to buy a $100 knife. The numbers are only slightly exaggerated. Transferring money is incredibly expensive.
