I totally get your point. But you are failing to see something very important. The fact that Bitcoin is called an investment makes even a greater percentage of the population consider it. You say it is gambling. To some extent, this might be the truth. But then the big question arises. How many people does it sit well with to know that they are gambling with their money? Concerning regulations, this is certainly bound to happen. If Bitcoin will keep growing the way it is, the government will and can not leave it unregulated. So, it's not necessarily a question of what is called.
