Yes I always buy when the price drops sharply.
You should at every drip if you have the money. Bitcoin's price will increase a lot in the future so buying at any price makes sense but buying at low points mean you will easily make a profit. It can also take a long time but buying and holding is a good way to make a profit.
Its more easy to earn profit if we buy low price.
Although we dont get profit, at least we reduce the risk of lose if we buy low. Dont ever buy in the top.
