Good morning, when the market is good, what you need to consider is how to sell? When to sell? How to sell in batches?

According to the hexagram I previously cast, if I’m not mistaken, Bitcoin still has a drop ahead.
Currently, it is Renchen month, the water reservoir, and the first half of this year has been quite dry, with strong fire, water coming to regulate the weather, from the 14th to the 16th, Gui water is in command for three days, from the 17th to May 4th, Wu earth is in command.
Personally, I think the most valuable days are the 14th to the 16th, when Gui water is in command.
My strategy is to gradually sell the altcoins I hold; recently, their rebounds have been quite good.
I will not sell Bitcoin and BNB.
Why do I do this? Why do I think it will still fall and I shouldn’t sell?
First, they can rebound.
Second, I’m afraid I might predict incorrectly. If I’m wrong and the long-term trend turns upward, with these two main coins, although a bit slow, I won’t miss all the market opportunities.
I hope the coins I hold can rise a bit more.
Exchange more into USDT, then buy Bitcoin later.
My chance to buy coins this year, I lean towards the second half of the year.
This is based on my subjective inference.
