HODL Capital's recent tweet highlighted a notable trend in the Bitcoin (BTC) market. US bitcoin spot ETFs acquired a total of 17,941 BTC in September, surpassing the 13,500 BTC mined during the same period. This means that ETFs absorbed 100% of the newly mined Bitcoin in September. This trend suggests growing institutional interest in Bitcoin, as spot ETFs provide a regulated and accessible way for investors to gain exposure to the cryptocurrency. The increase in demand from ETFs could potentially drive up the price of Bitcoin in the long term, as it reduces the amount of BTC available in the market. As the cryptocurrency market continues to evolve, it will be interesting to see how spot ETFs shape the demand and supply dynamics of Bitcoin and other digital assets.
