Bitcoin Tops $81,000 as ETF Demand Rebounds and Dollar Weakens

• U.S. spot Bitcoin ETFs recorded $1.92 billion in net inflows over five sessions
• Iran sanctions, Treasury buybacks and a weaker dollar add to the macro backdrop

Bitcoin briefly climbed above $81,000 on August 25, extending its August rebound as renewed demand for the cryptocurrency coincided with strong inflows into U.S. spot Bitcoin ETFs and a weaker dollar.

The move also comes as new U.S. sanctions on Iran, expanded Treasury bond buybacks and concerns over currency debasement reshape the broader market backdrop. Short covering has added to the advance, but sustained spot and ETF demand suggest the rally is not being driven by derivatives positioning alone.

Why is the Bitcoin Price Rising Above $80,000?

Bitcoin continued to move higher this week as investors responded to a combination of U.S. policy developments, renewed spot-market demand, ETF inflows and short covering.
