The recent price rise in Bitcoin has not enticed longer-term investors to part with their holdings, and Glassnode data shows that the Bitcoin supply held by long-term holders has hit a new all-time high of 12.69 million BTC. This tops the previous record achieved in October 2020.

MicroStrategy’s recent Form 8-K filing with the United States Securities and Exchange Commission shows that the company bolstered its Bitcoin holdings by 3,907 BTC between July 1 and Aug. 23. The company bought at an average price of $45,294. This brings MicroStrategy's total holdings to 108,992 BTC, with an average price of $26,769.
