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.
You will never remove theft from one currency.
Where there is currency, there will always be theft.
