Re: [ANN] Ethereum: Welcome to the Beginning

I read somewhere on the thread that Ethereum will have POS implemented is that true? and when will it happen?

Yes, but no one knows when, maybe in a 1/2 of year.

Does that coincide with PoW?

Many coins started with PoW then switched to PoS, I guess ETH will do the same. So it will be completely PoS coin without PoW/PoS mix.
