I think, both mines & investors dumped. Otherwise, price could not crash like this...
price crashed because it was a fake price due to the fake pump. this coin is not really offering anything good to make it worth 6-7BTC per coin. and as we keep seeing the price keeps declining and it is now down to 0.06BTC and is barely keeping up.
the dumps by the miners and investors is what speeds up the process not the main reason.
