Bitcoin market conditions are predictable but reality can be different so you should stay in regular buying as you will keep stashing into your portfolio whether the price of Bitcoin is bearish or bullish.
No one can predict the price of bitcoin and that is why it is risky for a newbie investor to think he can start his bitcoin investment by timing the dip. It is the same reason why traders are run at loss because nobody can know the next price movement of bitcoin. Assuming it is possible nobody will want to hodli but they will prefer to sell and buy back to increase their bitcoin portfolio. This is why investing with DCA as a new investor or low coiner and hodli for long is the best because you don't bother about the market but think more on how to stay focus on accumulating your bitcoin regularly overtime.
Since your portfolio is a decent size you can be aggressive in buying bitcoin during dips. For example, if the price of Bitcoin is going up for 6 months then you continue to accumulate normally and if the price goes down for the next 1 month then you should continue to buy aggressively.
It all depends on how you have prepared for your buying orders during the dip or pump. Those whose portfolio is already in a decent size might not care about DCAing when the price of bitcoin is pumping because they will only be able to buy very little quantity due to high price and that might not have any effective value on their portfolio. So such investors only prepare to buy bitcoin at the dip in order to buy large quantities at a cheaper price.
