Bitcoin or any crypto currency is not something that could be shut down, no matter what you do. All the countries in the whole world come up with a ban that will stop all exchanges and all miners and everything in between and basically make it illegal to even own bitcoin and even after that bitcoin will still live as long as it runs on a single computer.
Considering they can only slow down bitcoin by doing that and dropping the price there is absolutely no logical way to shut down at all. You can't just take out wallets and close all computers that ever had bitcoin related things on them, its not possible, you can't even do that for small coins let alone something as big as bitcoin. Which clearly shows that Joseph Stiglitz has no idea how bitcoin works at all and should not be cared about at all.
They want to ban bitcoin by the use of force and they want to impose their will to the public but as long as the reasons of why bitcoin was created in the first place are still there and they do not fix them then bitcoin will remain strong regardless of what they do, we will not have any need for bitcoin if governments managed their economies in an honest way and they did not manipulate their currency but they have decided to do so and now the people finally found a way to create a currency they cannot manipulate and this is why bitcoin does not stop growing.
