If you have set up your reserve funds that can be used to buy more Bitcoin in the dip together with your regular DCA, and if you have an unexpected amount of money, you can lump sum immediately without thinking twice. Emergency funds reserve funds and floats are good to be in place so that whatever happens in the market will not be your concern.
I always have a budget before starting investment first, of course the reserve funds will be prepared to buy bitcoin at once when the price is down without thinking twice like the price a few weeks ago which was in the range of $57K I bought at once with a fixed reserve fund for regular DCA to keep going according to the original plan.
Emergency funds for living needs have been prepared.
Emergency funds for bitcoin purchases when prices drop are prepared.
So I will not think anything when the decline, even it is happy when buying because it will get more bitcoin.
