Scalping is best to increase the volume of bitcoin and also increase the chance of profit making if the chance increases but for holding the price of the bitcoin either increase or decreases but the volume of bitcoin remains the same
That will depend on how good your skills in trading because in these situations, it is hard to find a good time to enter the market, and if you can not analyze better, you will buy at a high price, and you will not know if the price will still up or down.
But if you think that you don't have better trading skills, maybe it is better to hold your bitcoin for a while and waiting for the price increases, so that will give you a chance to make a bigger profit.
You can buy bitcoin at a low price for this day and hold it for tomorrow, and if the price can increase tomorrow, especially if the price can jump to 10% from the price, you can sell it to take the profit.
Before you determine which you can choose, you should think twice and don't just follow other people's suggestions.
