The consumption of a large amount of energy when mining cryptocurrency and, most importantly, the emission of a large amount of greenhouse gases can become a serious problem in the future. In light of the decisions of the last summit of the G20 countries related to commitments to prevent global climate change, states may well agree to some restrictions on cryptocurrency mining.
So, Sweden has already turned to the EU countries to prohibit the mining of cryptocurrencies using the energy-consuming PoW algorithm. This can negatively affect Bitcoin in the first place. The main thing is that such prohibitions are absolutely real.
