I just truly believe that there isn't really any shot for these companies to implement a currency or payment service that can use the blockchain technology that bitcoin has, because there will be a need for them to mine and run nodes, which in all reality probably can't compete with the hash rate that bitcoin already has.

It just seems to me that because Bitcoin was the first one to create a public P2P network that anyone can verify at a given time, that it has created a niche that no one else can essentially copy; instead they would have to use bitcoin themselves in order to use a blockchain based currency.
