There are likely even guys here who have been stacking bitcoin for several years, and who might feel that their progress is slow, yet part of the challenge is to keep stacking even during times that the BTC price is going up... and each person has to figure out how to deal with how to keep stacking and dilemmas regarding the extent to which they might hold some cash in reserves for buying on dips... dips that may or may not end up happening.
you have said right, however I agree with you more that even though one has some funds kept to buy the dips there is no guarantee that the dips will even happen, so what's best is to keep stacking up whilst hope the dips happens some day which one could grab the opportunity to buy more, having the benefit of buying in discount. Its also good to plan to buy the dips, buy lump sum but best buying gradually and consistently which is more likely to be referred to as DCA.
