Home » Bitcoin Bitcoin holdings of public companies surged in 2021 Bitcoin Reading 2 min Views 3 The amount of BTC held by public companies gained significant market share from that held in spot ETFs since MicroStrategy’s “Bitcoin for Corporations” conference in February 2021. The quantity of Bitcoin (BTC) held by private corporations increased significantly during 2021, building on increases from the previous year. In a Monday tweet, on-chain analyst Willy Woo claimed that public companies holding “significant BTC have gained market share from spot ETFs as a way to access BTC exposure on public equity markets.” This has been more noticeable since MicroStrategy’s “Bitcoin for Corporations” conference on Feb. 3 and 4, 2021. The online seminar aimed to explain the legal considerations for firms seeking to integrate Bitcoin into their businesses and reserves. Michael Saylor’s MicroStrategy is a leading business intelligence firm and is known for being particularly bullish on BTC, owning almost $6 billion in crypto assets. On Thursday, Saylor’s firm purchased a further 1,914 BTC worth $94 million. The company has gained more than $2.1 billion in profit since its initial Bitcoin purchase in August 2020. Woo referenced a chart of BTC holdings inside exchange-traded funds (ETF) and public company treasuries available for public ownership via equity markets, based on crowdsourced corporate treasury data. Spot ETFs hold BTC, as opposed to futures, in which companies purchase exposure via contracts from the Chicago Mercantile Exchange futures market.
