It’s a solid strategy for anyone who wants to build up their crypto stash over time, especially if cash flow is tight.
Yeah, I think the fact is that most people simply don't have a big lump sum amount to invest in Bitcoin, so most people are happy to do DCA.
You can still have a big am ount to lump sum but because you want to take advantage of the market volatility, one can share his lump sum into various parts and spread them out in different weeks to buy bitcoin. A new investor can have $3000 and does not want to go all in at once, he share share $3000 into 30 weeks and buy with $100 every week because he knows that he has the high chances of buying more with DCA approach than lump sum.
At the end of the day it is impossible to predict what strategy is best when you ignore things like fees, because it depends on the future price of Bitcoin, which is impossible to predict.
Everyone needs to figure out what strategy works for them and use it to accumulate bitcoin. The important thing is that your bitcoin stash should be increasing overtime.
Many people will try to show with past data that DCA or lump sum is better... those analysis are not interesting because you can choose different time periods to make either one of those strategies the best one.
I agree with you.
