Source: us-gaap CryptoAssetFairValue, CryptoAssetCost and CryptoAssetNumberOfUnits; dei EntityCommonStockSharesOutstanding. A tagged coin count is left out when it can't be right: fair value divided by it gives a price the coin never had, it goes with a total smaller than the current and noncurrent parts added up, or an 8-K within three weeks says something more than 50% different. The 8-K amount stands in for it then.
