If you start by saying you will take over something established, you can't be taken seriously. Do your thing, grow it some, prove its worth, then we'll talk.
It's like someone with an idea of a new operating system saying Bill Gates "step aside", everyone in the room will have a good laugh !
I dont think so that this is the end of bitcoin or blockchain. It is the start of both these because many people still do not know anything about bitcoin. The awaarness about bitcoin and the place where to keep them is now prevailing in the world ans soon all the people will use bitcoin and bitcoin blockchain wallet for their daily use and transaction. It is beyod sense that these both are going to end.
