Currently more and more coins are using PoS. PoW is already becoming a very unpopular and persecuted consensus. Various governments oppose PoW, make various dubious arguments in favor of PoS, even trying to transfer bitcoin to PoS. This trend has been rapidly gaining momentum since last year. If you take the crypto industry 8-10 years ago, there many popular cryptocurrencies were on PoW, and now on PoS. Cryptocurrencies have long been moving toward regulation and centralization.
It's all the governments' fault. They want to control Bitcoin and other cryptocurrencies by enforcing KYC/AML across every single centralized exchange. When they can't control trades performed directly on the Blockchain, they quickly attack crypto by saying it's "harmful to the environment". But the thing is Bitcoin can be as clean as any ordinary PoS coin if miners use alternative/renewable energy sources. If the vast majority of miners begin using solar, wind, geothermal, or even hydroelectric energy, then PoW would be environmentally-friendly.
This is nothing more than a plan for governments to push PoS in order to centralize the entire crypto/Blockchain space. Sadly, Ethereum fell for it by adopting the consensus algorithm. Other cryptocurrencies like Cardano, BNB, and even Polygon (MATIC) are PoS, so it should only be a matter of time before Bitcoin remains as the sole PoW cryptocurrency in the world. Even Zcash hinted the possibility of switching to PoS for "self-sustainability". I'm pretty sure whales will fill their pockets with a lot of money, leaving the little guy out of the system. What matters is that Bitcoin remains a PoW cryptocurrency to resist the evil forces of centralization. As long as it stays that way, no one will be able to stop it. Just my thoughts
The important thing is that bitcoin does not eventually break down in the face of government oppression. The government has two ways to fully control bitcoin:
1. Moves to PoS, controlling the blockchain, transactions and capacity, blocking and sanctioning any address. The perfect control tool. But there is a nuance here, a move to pos may kill all faith in bitcoin, so such drastic measures may turn out badly for the value of this asset.
2. The regulation of cryptocurrencies is being actively discussed. I recently came across another article where government officials are proposing to introduce KYC for bitcoin addresses. A nonsense that breaks all principles of cryptocurrencies and bitcoin, but it is already implemented. I read that in Dutch exchanges when transferring funds you have to give personal data not only of the sender, but also of the recipient. How do you like it? Alas, this is reality. This may take years or decades. After all, some 10 years have passed and now people are already more relaxed about KYC in cryptocurrency.
