I think that you have been saying the wrong thing Popkon6 since you were brand new on the forum for the past 2.5 years.. and you are wrong.
DCA does not get you lower BTC purchase prices even if you buy every single week.
If we look at your own forum registration date in October 2022... bitcoin prices were at their lowest right around November 2022, and you could have had bought a couple of BTC for around $16k each.. so $32k for two BTC.
Investment with DCA strategy and without it results in different entry approaches.
With DCA, you identify yourself that you're going to make multiple purchases with time and are preparing your investment capital for it too. It also does not require you to find one or few perfect entries. It reduce your stress of finding such entries for your investment portfolio.
Without DCA, you have no idea of whether you will make only one purchase with all money you have, or will do several purchases. It's first big difference, and another one is without DCA, you tend to find perfect entries that is full of stress and can cause bad decisions.
