How to face a drop of $BTC ? With dozens of fractional buy orders following the price all the time. If you place a single order at a very low price, the price may not drop to the expected value and may rise again. If you made fractional purchases, at least you will be able to buy a part of the drop and will profit when the price returns to maximum values. Additionally, you will risk less of your capital. Note: do not hesitate to review very low-value orders if the price moves in the opposite direction. Your goal should be to track the price.
