We all thought we had reach a bottom around 6K until some few people decided to ruin everything for all of us. Gladly, their mission failed (well, for now) and I'm really happy for that. I hope the same happens to anyone who tries to ruin Bitcoin's price furthermore.
I think that this sort of manipulation usually happens in cryptocurrency. And it will still happen to it. Many people enjoys how volatile bitcoin is. And probably that is the reason why many people are just manipulating the price of bitcoin easily.
