For me if another price drop happen i will add more coins. Corrections and pullbacks are normal since there are negative new about a stock/coin that you are buying. If you are investing and trading then you should know how to take control and get an advantage to people who are fearful.
Well this strategy actually work provided if the correction does not takes place for a big amount. Say you keep buying and prices keep falling then after certain point you wont have money when it has reached the low. So i generally buy once and then wait till the rise again starts to happen and then start buying back again.
