BTC Long-term Trading Logic

Currently, the first strong support zone for $BTC is approximately between $50k and $55k, and another extreme support zone is between $45,000 and $50,000, which may take longer to confirm.
However, I know that no one can buy exactly at the bottom, so I decide to build positions in batches.
As long as the final average cost of holdings is controlled within 20% above or below the bottom price, I can accept it.
This is my long-term approach.
BTC Short-term Trading Logic
From the recent rebound high of $82k to today’s drop below $60k, BTC has fallen by 20k points.
Even if lower prices appear later, after such a large adjustment, the probability of a rebound wave is very high.
Therefore, whether or not there will be further dips later, I choose to add some positions first.
The previous bull peak was at $69k.
Estimating at a ratio of 0.7, the ideal bottom is around $48.3k— but this is not guaranteed to happen.
I think there’s no need to insist on the absolute bottom; finding a relative bottom is already enough.
