The concept is called dollar-cost averaging. Nothing new, been around for years, but I think it is the best way to invest long-term in crypto and take advantage of the volatility.
Dollar cost averaging is very simplistic and not a magic bullet...
And does not increase the expected return of an investment portfolio...
But it does increase volatility and risk of ruin.
Dollar cost averaging works best with blue chip stocks in a long-term bull market...
So it creates an illusion of effectiveness.
Conversely...
Dollar cost averaging works worst with junk stocks or crypto because many of these securities GO TO ZERO.
A much better approach to crypto is to know when to GET THE HELL OUT of a coin...
You have to learn the signs of an inevitable Death Spiral...
As opposed to buying a dead coin all the way down to zero.
