even if xt seems a winner at one point, i think core will win in the end. i think there can't be any other way, no alt pretending to be btc is going to become btc, thats insanity.
Completely agree. It might not win in the first place but you're right even if it does win it will only be for a short while and people who choose it will bounce back to the original Bitcoin because there is and always will be one bitcoin and no altcoin can take it's place.
To answer your question OP, whatever happens with bitcoin I will always support only one cryptocurrency, which is Bitcoin.
