According to Odaily, the 21st week of the launch of US Bitcoin spot ETFs has seen these funds purchasing 2730 BTC. HODL15Capital, the monitoring agency, reported this significant acquisition. This development marks a notable increase in the involvement of these ETFs in the Bitcoin market.

The purchase of such a large number of Bitcoins indicates a growing interest and confidence in the cryptocurrency among these ETFs. It also reflects the increasing acceptance and integration of Bitcoin into mainstream financial systems.

However, it's important to note that the cryptocurrency market is highly volatile, and investments in Bitcoin can be risky. Investors should always conduct thorough research and consider their financial situation before investing in Bitcoin or any other cryptocurrency.
