The recent increased is due to some manipulators. They started the rally then others think of it as a start of halving speculations so they follow the trend and buy more coins resulting for what the price is sitting today.
I don't know about that thing that the rapid increase of bitcoin's price is due by manipulators. I'm just even thinking that it is because of the halving.
Since it is near to happen so signs of it are already happening. And it really made us profitable.
So for sure, halving is going to be so very profitable.
There's no way a price will surge just because of halving itself. It must be started by shaking the price up and that is the thing started by the manipulators. Also no way all people have the same thinking that they will do a massive buy while the price is not moving.
Because the manipulators succeeded, people think of this as halving effect so they ride the train and buy more coins to take part in the upcoming halving.
