Bitcoin ETF Inflows Near $3B as Buying Spree Extends to Sixth Day

Investors have been buying Bitcoin exchange-traded funds for six straight days, keeping the funds on a winning streak.

Since September 17, over $2.8 billion has flowed into Bitcoin ETFs from asset managers such as BlackRock, Fidelity and Morgan Stanley, per data from Farside Investors.

Monday saw nearly $1 billion in purchases, the largest daily inflow since October 6. On that date, the funds attracted more than $1.2 billion and Bitcoin reached a record $126,080.

Despite the inflows, Bitcoin's price has risen only slightly. It was trading near $83,975 on Friday after touching $87,330 on Monday. Over the last week, the cryptocurrency has gained almost 4%.

Bloomberg ETF analyst James Seyffart noted that although Bitcoin has fallen from its weekly high, the typical ETF investor is now profitable because the estimated cost basis climbed above $81,72 for the first time since January.

Interest in Bitcoin picked up after the U.S. Treasury said in August it would expand its liquidity-support buyback operations by at least twice.

The announcement sent 30-year Treasury yields lower and the dollar weaker, boosting Bitcoin. However, yields have since climbed back.

Last week, Bitcoin extended its rally despite a legislative setback — lawmakers killed the Clarity Act — and an interest rate increase by the Federal Reserve.

Some analysts believe Bitcoin has entered a bull market. CryptoQuant reported this week that the cryptocurrency has moved above its 365-day moving average, indicating the end of its bear phase.

Bitcoin hit an all-time high of $126,080 last October but later dropped following a record liquidation of over $19 billion in positions. The "debasement trade" — buying assets to protect against currency depreciation — has resurfaced, and Bitcoin has gained as the dollar weakens.
