the future is definitely going to be really bright and it will make you big money for sure, i hope that im right
I too think bitcoins will terminate most of the other processors like paypal, payza, etc and mainly because of the transparent and yet very secure features of bitcoins. We can see how much each of us have in bitcoins yet it can not be hacked or stolen. Yes, these features decides the future of bitcoin hopefully always in positive aspects.
I don't think It will terminate all the payment mediums. It will over cross paypal and It occupy the number one rank in payment windows. Other than that bitcoin will become well money in future and all the will accept bitcoins and even paypal also may open sending bitcoins through paypal medium.
