How could bank or any other financial institution possibly control bitcoin? This makes no sense, as well as this question.
They can't control the system taht is independent and decentralized. Maybe you are mixiing that with the fact that some banks are expermenting with bitcoin and trying ti use it for their benefit. But this is not the same as controling it.
Exactly.
If anyone knows just the Slightest bit about Crypto Currency, they will realize that the WHOLE DESIGN is based off being decentralized.
Asking that question of "What if" isn't even a logical question.
There is NO "what if".
It won't happen. It can't happen. Like. The word "Impossible", does not even begin to describe it.
