Bitcoin reserves held by known over-the-counter trading platform addresses have fallen to an all-time low of about 123,000 BTC, according to monitoring by Darkfost. The balance was close to 500,000 BTC in September 2021. The decline may reflect investors retaining their Bitcoin, reduced concentration among miners and other holders, or a preference for selling on public markets. With fewer coins available through OTC desks, demand may increasingly shift toward direct market purchases, which could support prices.
