The price drop could have been indeed caused by the drama around the forks and because many don't understand that Bitcoin is not the same as Bitcoin Cash, Bitcoin Gold, Bitcoin Apple, Bitcoin Banana and whatever altcoin some decide to fork.

Bitcoin supply is not related to any of those altcoins. But I understand your point. A lot of people don't read where they invest, and then the lack of knowledge makes them dump, often the wrong investment or at the wrong time because of that. Maybe you should try to read more about Bitcoin too.
