If you really understand the DCA strategy and you have been using it to accumulate bitcoin for a long time, as you said, you will understand that the DCA strategy allows investors to accumulate bitcoin both in the bullish and the bearish seasons, which is one of the reasons why most investors adopt the DCA strategy when they are investing in bitcoin. Accumulating bitcoin in the bear season alone will not guarantee you a bigger profit in your bitcoin investment; the things that will determine how big your profit in bitcoin investment will be are how much money you have invested in bitcoin and how long you were able to hold your bitcoin.
I have a strategy for this which worked. If the bear session has just started, do not buy bitcoin. If the bear market worsen, you can start accumulating bitcoin. If bitcoin fall far more than expected, that is indicating that you should buy huge. The money I suppose to use to accumulate is divided into 2 each time which I will later use to buy bitcoin at once later if the price fall more than expected.
This investment strategy of yours is not correct at all. You should keep in mind that there is no particular time to buy Bitcoin. If one uses the Dollar Cost Averaging method to invest then he can easily buy Bitcoins in both the dip season and the bull season. Dips can be your best opportunity to buy bitcoins at low prices even during dips you can buy more bitcoins which will become more profitable for you later on during bulls. The only benefit of investing during the dip season is that you can buy more bitcoins at a lower price, but those who just wait for the dip period may miss out on their investment. So buy bitcoins regularly and hold your investment for long term.
