New Bitcoins are started every day.
Can we create a new, successful, Bitcoin... only if the majority agree with your beliefs.

My argument for a new bitcoin is simple: Most people has lost bitcoin due theft or data loss, or missed the boat.
So most coins in circulation are held by thieves, oligarchs and .gov.
Therefore we don't have anything to lose by voting with our feet and go over to a new coin.
I'm sure you are not holding much bitcoins..!
You mentioned most of coins in circulation are held by thieves, oligarchs and .gov. I agree with you to some extent but not all bitcoins are held by them.. not everyone lost there all bitcoins in mt-gox..! many of us were smart enough to know that how vulnerable it can be having bitcoins in an online exchange. so You got a thought but i don't think it has much substance in it..! You forgot about all the members who are still holding their BTC's and are very optimistic about it
Ohh btw there are altcoins launching every day... why don't try those may be someone will take place of BTC on day..!
