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.
Surely Investing in Bitcoin should be done through DCA to enable you invest regularly without considering the bear market or bulll run. Saying that you will buy Bitcoin only when the market worsen, is not a good way or method of buying Bitcoin. Of course it is good to buy Bitcoin more when the market dips, but shouldn't be what we only think and hope for , but should be a second option from the DCA. That is why it is advised that we should have a discretion income to be able to buy Bitcoin through DCA or buying on dip and or lump sum. So that we dont only consider buying the dip method as the only priority.
