So far in September, Bitcoin ETFs have accumulated $1.39 billion in net inflows. This capital inflow reflects growing interest from investors looking to position themselves ahead of next week's Federal Reserve (FED) meeting, which will determine whether there will be changes to the dollar's interest rate.

Expectations largely point to a rate cut, which would reduce borrowing costs and could inject liquidity into the markets, benefiting assets like Bitcoin. The performance of these ETFs directly impacts the currency's price. This is because the fund managers buy and hold bitcoin in their treasuries to back their holdings. When demand for these financial products grows, firms acquire more BTC on the market, which, due to the law of supply and demand, drives up their price. As a result, the price of Bitcoin has stabilized between $113,000 and $115,000, after starting the month at $107,000.
