Those financials show digital assets totaling $24715 and that was only as of 2019 and was not listed in the 2018. If they "have" 576 BTC then they are not reporting them on the balance sheet, which means the "company" doesn't have that many.
Oh and you also have this nice disclaimer on their financials:
Disclaimer
Some of the historical figures provided here, dating prior to January 1 2018, such as past stock issuance, Bitcoin holdings, debt (or lack thereof) were provided by and or disseminated from emails and other communication with the old CEO, Bill Schaefer. No
audited or unaudited financials were ever received from old management.
So they are "guessing" they have 576 BTC.
