Yeah actually @Jay tried to emphasize a bit on that scenario, so however as an investor that has a lot of funds or other physical investment that's generating you income on a consistent basis, it doesn't necessarily mean that you most use DCA strategy all the time but instead it could only serve you as a back up plan of accumulating strategy.

So if you are financially stable you could actually utilize the advantage if the Bitcoin price is dip by accumulating using the Lump sum strategy that enable you to take advantage and accumulating a huge amount of Bitcoin at a time.

So in this case you don't have to rely on DCA strategy because you can buy everything at once then if maybe later on the Bitcoin increases perhaps you can then  come back to the normal DCA strategy.
