so yes, your strategy does indeed work but until the market suddenly turn bearish then you will more likely to lose your money since you buying the dips meanwhile the market getting even more correction.
as for your strategy of buying a coin that doesn't have rally yet at bullrun meanwhile the other coin have been having some good rally is really true, its just matter of time until some whales picking it up and try to pump it or at least some people realize that the coin is undervalued and then try to invest into it.
but it only works at the early bullrun though around mid to the end phase of bullrun most of coin already having bullrun, the one that doesn't usually just not gonna have bullrun doesn't matter whether you gonna wait it or not.
This is why I think it is quite obvious that we are going to end up with a good result with this strategy as well in most cases. In the cases that doesn't do that well ,we could just end up not really caring about it all that much and look to get out, or do DCA and wait for long term recovery to happen.
