Everyone was blaming September for the dip like it was a dip holiday and just waiting for October for the pump. And as soon as October came - and I mean literally, like the first day of October - prices started to go up and it started to pump. How??
Why do we need to give reasons for even single price movement?
Just normal to ask for reasons though, maybe the OP wanted to understand how the market works in a pump and dump scenario.
The answer that you will get, more often than not, is just going to be a combination of coincidence and normal market fluctuations.
Yes, maybe you can go back to the basic law of supply and demand as reasons.
People like to bring up all sorts of infographics to prove their point that some months perform better than others for crypto, but all of this could literally be due to chance and nothing else. If there was to be a relationship between what month it is and bitcoin price then wouldn't you think that people would trade the hell out of it already?
Well numbers don't like, September historically was a bad month. And October was the start of a bounce back and recovery.
