The only time it is good to switch is if you know ahead of time that the game show host will in fact open a door other than your own that does not contain the bitcoins.

On the other hand if the host announces to you that he will do it only after you picked your door, it's better to stay with your door. Why? Because if the host wants to beat you then he will only pick a door if you picked the right door to begin with, in an effort to get you off the right door.

And all of this presumes that Monty Hall knows what is behind the doors. Or that Monty is even alive.
