Is BITCOIN going to close?

No, the close of various black markets will make it loose a tiny bit of value but new black markets will open to replace the ones that have been closed, but it will not close. I think it might reach it's peak within 5-10 year's time but it's not dead just yet, it's dead when the value is close to null. But never will close the value will just be worth nothing but that is going to be in a very long time.
