When buying the currency of my choice in the early stage, I usually choose to gradually build a position when the market is relatively sluggish, and operate in batches. I buy a small amount when the market drops slightly, and increase the purchase force when the market drops sharply. When the market rises, I generally do not enter the market, but wait patiently. By buying in batches, I try to reduce the price risk of a single transaction. Of course, this also depends on the funding situation. If it is a small position increase, I will buy it as soon as I have the funds. For projects that I am particularly optimistic about, I usually buy them decisively at one time without dragging my feet.
