What would be the price of Bitcoin if someone would invest 10 billion USD in one day?
It would be interesting to know what price would be.
How i can calculate?
Let me ask you something dude? why are you asking this things? It sounds that there is someone who is planning to pump bitcoin

10 billions was a big amount and honestly I don't have any idea how much will price of bitcoin become maybe close to 1700$-1800$ something. And if ever it happen expect too that there will gonna have a bit decrease also but it can recover again.
