Many things are caused by quantitative changes leading to qualitative changes, taking these 5 weekly bullish candles of BTC as an example;

First: The market is still in fear, the voices of "the rebound is not the bottom" are deafening, echoing everywhere.

Second: Although it is not as fearful anymore, there are still concerns about new lows, this still belongs to quantitative change, the nature has not changed;

Third: Doubt, continuous doubt! Has the rebound reached its target? Are the bears dead?

Fourth: Opposition! Sure enough, it can't go up, it must have reached the top, the bear liquidity has been completely cleared! (I was also caught in it)

Fifth: Bull return! Quantitative change has finally led to qualitative change, market sentiment has seen a 180° reversal, greed, desire, regret, are flooding the entire cyber space...

Interestingly, once qualitative change is completed, quantitative change will begin to fade, perhaps soon after, we will experience a new cycle:

Greed, worry, anxiety, opposition, bear return!

BTC is still there, but many people, much money, have already vanished...
