Re: what are the chances that more than 21 million bitcoin will be created?
I'd prefer that Bitcoin stays at 21 million so I can one day claim to be a millionaire when the price decides to go ballistic and each BTC equals $1 million or more.. 
I agree with you ,if they will try to create more bitcoins then will be the end of bitcoin.The value will drop a lot,people will lose the trust in bitcoin.
