One big point was the adjustments after the 2017 bubble.
Then there's a ton of speculation, since the market is not regulated. The exchanges are not regulated and some may have bots artificially affecting the price up or down.

More and more voices are telling that currently Bitcoin is oversold, which is an unnatural situation.


My personal opinion is also that we face a strange situation. Many voices that did or are preaching even now Bitcoin doomsday were proven to be accumulating Bitcoin behind the curtains. Some have the financial power to keep the price down for longer period than most of us would expect.
