So I guess that means my public/private address will also exist in the new Ethereum coin, and probably Trezor devices will have an option to use Eth Classic, Eth POW, and Eth POS.
But how would I tell my Trezor to use POS coin, under the existing POW address?
Also, what's stopping me from selling my POW coins and adding them to the duplicated coins in my POS address?
