There's a good chance they may impose restrictions or outright bans on small-scale bitcoin mining because it is the most deteriorating form of crypto mining that exists today. Large-scale minings aren't that debilitating as they use their very own energy source as a way to power their operations. Small-scale GPU/CPU miners use their local grid's electricity supply and therefore their local energy resource to power their operations which is not only sustainable on the provider's part, but is also detrimental to the quality of the environment. Add to this the fact that more and more people are becoming more aware and active in protesting for the welfare of the environment, and it's sure as shooting that they'd impose such bans in the future if this type of situation keeps up.
Whether states will ban or tighten the mining of bitcoin or other cryptocurrencies with the PoW algorithm will depend on how they solve the current energy shortage problem. Most likely, the state will discuss this issue and such a decision is quite possible. However, this is unlikely to affect the circulation of bitcoin.
According to Blockchain.com, 90% of all bitcoins were mined 12 years after miners received the first bitcoins. This means that about 18.9 million coins out of a maximum supply of 21 million are now on the open market. Therefore, even if states decide to ban bitcoin mining, and even if they can control such a decision, then bitcoin may well get by with the current amount of almost 19 million.
