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.
If you have the budget to buy when the price dump it is good for you to consider but it is not always necessary for us to always but when the price dump because there is also a possibility for the price to continue the dump or the price drop so it is better to analyze first the changes so you could limit the loss you could deal with buying or a part of trading transactions.
I am seeing a crash today after the pump in price, bitcoin will touch the 9.000 again or maybe 8.900 USD.
this is normal before entering the 10.000 USD and be stable there.
Price is not rising like it was in 2017, but lets hope at the end of the year what will happen The rise of price in bitcoin will be slow but sure.
