Very well said Charles, I have used such formula in my bitcoin buying process sometimes a d it do work for me, in the sense that I try not to put everything down in the market at once, and once I notice that if I bought bitcoin, I always give at least a week interval before I visit to the exchange again to know if the price decrease further so that I can buy more.
With DCA, you only need to plan your investment and purchases on daily, weekly, monthly or longer time frames or just use your available investment capital for purchase anytime you have it.
