Unpopular advice – but the empirical data shows that counter intuitively lump sum buying (even at an ATH) beats DCA in almost all cases over time

I think DCA is an excellent strategy, and it's what I do because of the nature of my financial situation, but for those who are investing in crypto from their pre-existing savings and who have an assigned budget they are planning to invest, the empirical data says that lump sum buy strategies almost always beats DCA.

This article does a good job of summarising both the theory and practical aspects of why lump-sum investment mathematically beats DCA over the long term (and most of us here appear to be long-term investors)

Also on the subject of data, this is a really unpopular opinion, but there is a huge amount of empirical data to show that TA rarely if ever works, and buy and hold beats day trading for almost all investors.

*For those arguing about this, try and find a period in crypto over more than 3 years where DCA'ing a fixed sum over the long term beats cash injecting it immediately. The longer the time period you take to inject the money, the less you make in almost all cases.
