Yes.  And some ways are better than other ways, and as you know we are not really talking about trading in this thread or even proposing it as a better way for anyone (absent those who build a specialty or who want to spend time in this kind of activity - maybe like a profession), so no need to confuse matters more by suggesting that we might be talking about those kinds of things trading things as if they were even comparable or something that most normal/regular guys should be considering in terms of the bitcoin accumulation journey.
 
The most basic thing that we are talking about in this thread are the various ways to accumulate bitcoin, and so we have some agreed-to presumptions that we are considering various ways to attempt to accumulate BTC in the ways that are best tailored for each person.  So if we are talking about DCA versus buying on dip versus lump sum buying, then I still am gong to suggest that DCA tends to be the best for the newbie until he gets to a certain stash size.  However, lump sum could be equally well, if someone has a lump sum to get started with a lump sum, and then if he is a newbie and has not reached his accumulation strategy, the he should supplement the lump sum with DCA and buying on dips. 

Where we likely disagree the most, is my assertion that buying on dips is likely ONLY going to become a superior strategy after the person had already accumulated BTC, whether he did that buy DCA and/or lump buying and/or by some other way.
