Anything's possible, Bitcoin price could go strata-spherically high or it could become worthless. It's unlikely to become worthless now its established as a store of value but in some extreme circumstances it's possible. Under other extreme circumstances it could become the biggest market on the planet. For now I think it will follow a midway path and go up in value, but not to the million dollar Bitcoin level.

no unless something happens that kills the internet permanently.


yes.


depends on what you call "very, very high". but the price will most likely go up as time goes by. browse around the speculation board to see what people expects the price to be in the future.
