This proves my theory
Dont deal with absolutes and you will have less disappointment in expectations or observations. An immediate change in price is usually quite artificial where as the effect of less sellers occurring in concordance will be an ongoing bullish change in sentiment. These kind of price changes are an effect underlying the normal market trade, it accumulates into a price change but its not a force that appears and waves a flag to make itself clear.
Life would simple if we could always observe exactly why, but its not a mystery either from my point of view. I see the market as resembling chaos theory, its not random its natural but also very hard to track and predict. Which is good because that leads to long term investment being needed to capture gains otherwise lost unexpectedly in days you didnt expect a higher price. Market never really does what we want.
The biggest bar or move recently was linked to BTC shorts being cancelled out. Some people called that out as impossible or fake but it kinda matches on both sides. Where as this tax event is just a slow drip from a tap being turned off and its repeated annually anyhow, it maybe relates to the bigger changes in the last 12 months also.
