After Ethereum move from Proof of Work to Proof of Stake... I am not interested again for Ethereum.
Some my investment is on PoW algorithm coin.

Yes PoS is making the energy used more less. But there is the risk we get.
From decentralized going to centralized. Because mining with PoS algorithm more cheap, many people coming to mining.
If bad actor come they can have big portion in mining pool and make it more centralized.
