According to the latest report from asset management firm Ark Invest, nearly 70% of Bitcoin's circulating supply has not been moved in at least a year, indicating a strengthening base of holders and confidence among long-term Bitcoin investors.

Ark reports that OTC Bitcoin balances reached a one-year high in June, and by the end of the quarter, OTC Bitcoin balances had increased by 60%. The rise indicates that institutions and large capital allocators are paying more and more attention to Bitcoin as an investment option.
