What happened

Bitcoin miners have sold $1.78 billion worth of BTC in 2026, and Marathon Digital (MARA) disclosed it has taken $750 million in loans secured by its Bitcoin holdings.

Confirmed

Global impact / market context

The sales add new supply to the market, which can pressure Bitcoin prices, while the large loan indicates miners are using Bitcoin as collateral to fund operations or expansion, affecting their balance sheets.

Analyst inference

Supply from public miners is often overlooked, yet it can influence price moves when it appears at the market’s margin. Simultaneously, miners’ borrowing against Bitcoin reflects growing reliance on crypto‑backed financing in the industry.

Analyst inference
