About some individuals, these people are only looking on a single and not on a whole forest. They worried too much about how the price decrease without realizing how much it grows prior to price dip
This is definitely not about "some individuals"
As it is more about all of us because this is how human mind and brain work in general. Our expectations of the future events (in this case, Bitcoin's price) are intuitively based on, and subliminally affected by, the most recent happenings. So even if we know for certain that the last price decrease is only a minor correction, we still feel worried or even terrorized by this drop
It has more weight for our internal decision-making machinery simply because it is closer to us and thus influences us stronger. In other words, recent events have more weight than remote ones even though the former are temporary while the latter are here to stay (and despite the fact we may actually know that)
Bitcoin has retreated about 33% from this 2019 bullish momentum and it is currently trying to find bottom below 50ma. It will take high volume for bitcoin to cross $10,000 before Wednesday and we are expect this to happen. Bitcoin will definitely going to cross $20,000 before end of the year or first week of next year as we move close to the halving date.
