this moment is what some people are praying, when the price is drop it an opportunity for those who are waiting for the price to drop so that they can buy .
Anyone waiting for the price of bitcoin to dip before they buy is not DCAing but buying at the dip. DCA doesn't care about the price because you are to just continue buying regularly weekly irrespective of the price of bitcoin at that moment whether, it's the bull run or bear market.
A brand new investor should just start buying the moment he has figured out his discretionary income and have the basic knowledge of bitcoin. Waiting for the price to dip isn't the best because it will slow down your accumulation pace and you will end up with little bitcoin in your possession in future.
and if the price is drop it is a problem for those who have been holding for long time and those who buy when the price is high, the only thing we can succeed in bitcoin is to be patient and stay focus with a positive mindset
If you don't sell when the price drops, you are not at loss. I don't see why you said that the bear market is a problem for those who have been holding for long when they already have the experience and overcome it in the past. I think newbies are the ones that the bear market can mess with their emotions a lot.
Anyone who bought bitcoin at the peak price wouldn't have any problem or regret if he continues buying with DCA because that's the sole purpose of DCA to buy at any price level for a gradual growth of your bitcoin portfolio overtime.
