I am one of them too

Having stable coin is another way to prepare to buy bitcoin when it is down. I am sure that the bitcoin price will not just increase, but it will decrease too, and usually, after the price can increase, in the next moment or next day, the price will fall to the lower price. Bitcoin price will always be like that, so if you want to buy bitcoin, you need to wait for a while until the bitcoin price can go down, and you can get bitcoin at a lower price.

But if you already have bitcoin by buying in some range of the price, and you are afraid of the price will go down in the next hours, you can sell it for some amount to wait for buying at another lower price, or you can hold it for more. Bitcoin prices will not stay forever at a low price or high price, but the price will always volatile. Unfortunately, we don't know where bitcoin prices will move, and we can only predict what will happen in the next hours.
