I don't think this is the best time to use this term BUY THE DIP AND HODL!. This is because we are not in the dip, and we are in the bull market, because bitcoin has passed the previous ATH. What should be said now is DCA AND HODL!, because at the current bitcoin price, it is only DCA that is the best strategy in which some accumulating bitcoin can use to increase his bitcoin portfolio due to the high price of bitcoin.

I would not even lump sum if I have the money to do that, because bitcoin price go into correction, so DCA regularly either weekly or monthly and hodli for a very long time, and when the bear market appears again, you can buy dip and hodli. However, this is my personal thoughts that I am sharing, and we all have the right to do whatever we think is best for us, but you will be responsible for your own actions.

If you are brand new to bitcoin, you should consider all three options of accumulation: Lump sum , DCA and buy the dip.

If you are investing for several years, you might not want to consider some of the options, but even if you have been buying for 1-2 years, and if you all of a sudden have extra money. .Let's say you get a $3k pay out for something. .then all of a sudden you have $3k.  So how are you going to treat that extra money? 

I would think that you would want to consider all three categories, even if you might choose not to employ all three categories.. but the default still might be to put 1/3 into each, but if you think that we are more inclined towards up, then you might want to put more into lump sum in order to better prepare for up, since we cannot know if there is going to be further down.. so maybe you end up deciding to put 60% or 70% into lump sum and then divide the remaining part into buying on dips and DCA.
