Grant Thornton audits Coinbase last I checked. Hopefully they do a better job than EY. I doubt a "stablecoin" holding would count as cash equivalents, but not all cash equivalents are equal and the definition has changed over the years. Commercial paper, 1-3 month maturing Treasury notes, certificates of deposit, money market accounts, and savings account funds can all be counted as cash equivalents. For example, if you hold a two month commercial paper of another cryptocurrency company as Coinbase, this might qualify as a cash equivalent. Cash equivalents are not all equally liquid or risky. Even if all of the cash and cash equivalents are there and solvent, the definition of a cryptocurrency in a bankruptcy might not be settled in a court of law in such a way that it favors account holders of Coinbase held cryptocurrency over stockholders or bondholders.
