How much bitcoin do publicly-traded companies currently have on their balance sheets? Is the information available online? If so, where can it be found?
If a public company accepts bitcoin, it would be recorded on it's balance sheet as Cash. You might be able to discover the amount by getting lists of companies that accept Btc and then looking it up in their annual (10-K) and quarterly (8-Q) reports on EDGAR (https://www.sec.gov/edgar/searchedgar/companysearch.html).
cryptocurrencies cannot be considered equivalent to cash (currency) as defined in IAS 7 and IAS 32 because they cannot readily be exchanged for any good or service. Although an increasing number of entities are accepting digital currencies as payment, digital currencies are not yet widely accepted as a medium of exchange and do not represent legal tender.
digital currencies do appear to meet the definition of an intangible asset in accordance with IAS 38, Intangible Assets. This standard defines an intangible asset as an identifiable non-monetary asset without physical substance.
cryptocurrency is subject to major variations in value and therefore it is non-monetary in nature. Cryptocurrencies are a form of digital money and do not have physical substance. Therefore, the most appropriate classification is as an intangible asset.
Note: I have chopped out a few short quotations from a longer article. If you find anything surprising, you should read the full article for proper context.
So a Bitcoin holding in a business that follows the accounting rules mentioned by ACCA would show up as part of intangible assets in published accounts. It might not be separated out.
