Why wont they just implement replay protection, are they attempting to force all the weak hands to either not attempt to split there coins or take a risk as Trezor spells out here? Does 2x think that it really doesn't have to acknowledge its a fork and pretend that BTC is still there! We will see what the The Future Hodls's!
Best thing seems to just not touch them for a while after the fork, I mean your hodling right! There is still BtcGold to be split as well!
