Personally I will switch to Ethereum Classic, a crypto-currency I like a lot. However, most people will probable stop mining as there will not be a crypto-currency that propose as much security, safeness and peace of mind than Ethereum.
Do you believe ETC and ETH can both survive-- for how long? My understanding is that with both chain alive they inhibit each other to an extent, ETH fanatics have told me ETC has to die in order for ETH to be fully thriving?
