According to a report filed with the US Securities and Exchange Commission
[1], PayPal held $604 million worth of cryptocurrencies, including Bitcoin, Ethereum, Litecoin and Bitcoin Cash, as of December 31, 2022. Bitcoin is the largest part of PayPal's crypto holdings, accounting for $291 million. Ethereum was second, with $250 million, and the remaining $63 million was split between Litecoin and Bitcoin Cash. PayPal's crypto holdings accounted for 67% of the company's total financial liabilities of $902 million. The company's total financial assets were over $25 billion. Despite offering cryptocurrency services for more than two years, this is the first time PayPal has provided a breakdown of its crypto holdings in its annual financial report.
An article on Cointelegraph
[2] reports that PayPal keeps its customers' cryptocurrencies through the use of a third-party custodian. The company emphasized in the filing that it has a contractual agreement in place with the custodian mandating the segregation of customer assets and prohibiting their mix with the custodian's proprietary or other assets. However, PayPal stated that they cannot guarantee the effectiveness of these contractual obligations in the event of the custodian's bankruptcy or insolvency.
I'm not sure whether PayPal has enabled the withdrawal of cryptocurrency funds to personal wallets for all users. However, it appears that many still don't fully grasp the significance of the adage "not your keys, not your coins."
