The idea and concept of the Lump sum buying entails buying right away, it has alot to do with investors decision to invest right away with the available huge amount without considering market condition, maybe you are describing buying the dip instead of a lump sum buying,
I mean, if the market condition is favorable, then yes, 'Huge sum can be invested', this is lum sum investment all by itself.
Investing at a favorable market price is a plus point 'if achievable,' otherwise, it depends on person to person 'depending on the market condition they want to invest in.'
You are very new to bitcoin investment, and I will not blame you for reasoning this way, but when you fail to take correction from others who have gained experience in bitcoin investment and know how to invest in bitcoin better than you means that you are not ready to learn how bitcoin investment works. It will be difficult to predict when the market will be favorable to invest and accumulate bitcoin. Instead of staying put until a favorable market happens to invest in bitcoin, why don't you start investing in bitcoin with the DCA strategy? It is more effective to accumulate bitcoin than to wait for a favorable market. You are misunderstanding the concept of the lump sum strategy. The lump strategy has nothing to do with a favorable market before you can lump sum on bitcoin. The lump sum strategy is all about buying bitcoin with a large sum of money at once even though the price of bitcoin is high or low.
