The Bitcoin drop could be because of the Bitcoin fork of forks. Bitcoin supply is not scare after it forks. Do u agree ? This time it forked from Bitcoin cash.
No one can really tell what happened to the price of Bitcoin or any of the altcoins, cause they as well are going down with Bitcoin, but most of us believes that the price crash was due to the Bitcoin Cash fork (BCH SV and the ABC fork), and I too believes that, cause the price started dropping heavily and down to $4000 within an hour, and that was on a Wednesday.
