Ethereum is a bag of trash, filled with trash and stinking like trash. I think you are "new" in this game, or? PoS is not save, if you think so, be happy to invest in it.

I am a full proof of work miner. There is no "EierlegendeWollmilchsau" on the market and never will be.

You can not have a decetralised AND fast system without proof of work.
