DCA is a good strategy for regular people who aren't pros at investing. It saves a lot of trouble from trying to guess the best times to buy during market ups and downs. It's a way to invest slowly and steadily, which helps stop the urge to make big gains quickly. Professionals or more experienced investors often use DCA when they want to catch price changes. They can automatically make buy and sell orders based on how much the price changes and how much they want to invest. It's like a more advanced version of DCA. For instance, you could set it up so that if the price changes a certain amount, each new investment gets multiplied by 2 or 3 times.
DCA deviation multiplier
DCA #1 = Base Order - 1% = $29,700
DCA #2 = DCA #1 - 1% * 2 = $29,100 (Base order - 3%)
DCA #3 = DCA #2 - 1% * 2 * 2 = $27,900 (Base order - 7%)
DCA order size mulyiplier
DCA #1 = 1,000 USDT = 1,000 USDT
DCA #2 = 1,000 USDT * 2 = 2,000 USDT
DCA #3 = 1,000 USDT * 2 * 2 = 4,000 USDT
I think that your initial description of DCA is correct, and of course, you seem to already recognize that your DCA modifier is not really DCA anymore, but getting into a kind of DCA supplement that may well end up involving a kind of formula for buying on dips. Those are not bad ideas, but you have to be careful when you continue to add value in terms of making sure that you are not going to run out of money too soon because you were being overly ambitious in terms of buying too many BTC too soon.. but sure the idea is not bad.
Another thing might be to have a certain weekly or monthly budget that would be allocated for DCA, but if you are trying to employ the DCA to happen during the dip of any period that you choose, and if such dip does not happen, then you still end up employing the DCA for that period at the end of the period (after you had given it a chance to see if there might be a dip that allows you to buy a little bit more during the period with the amount of value that you had allocated for that particular DCA buying period).
I also think that his description of DCA is correct and somewhat really usable at the same time. The DCA works week during the dips because in those events we get the chance to accumulate more amount of Bitcoin with same fiat value. I also think that his DCA is too aggressive because he's spending a lot of money to buy too many Bitcoin in a short period and which is not going to be a good thing for someone who wants to accumulate a lot of Bitcoin. I also think that DCA isn't always needed for accumulation of Bitcoin because sometimes we may buy Bitcoin at higher price value and that's why it's better to divide the amount you have and invest those divided values on times when the price of Bitcoins gets a dip. I know that sounds greedy, but that way you will be able to accumulate a lot more Bitcoin then with the traditional DCA techniques.
If you still want to go with DCA route then I think the best way to allocate the monthly budget for DCA would be to wait for a good dip in price of Bitcoin and continue DCA from the time of the first dip. If you see no dips for a certain amount of time which is unlikely to happen because we all know the volatility of the market and due to which dips can occur at least once in a month. A wise dip purchasing is always needed to accumulate more coins and we can't ignore that fact. The best DCA strategy would be to wait for the DIP and purchase some amount and then wait for another DIP with even more intensity then purchase more coins, I know that won't be called as a true DCA technique but that will help to acquire more Bitcoin for you as an investor. Continue in that way until the process is completed and you have allocated everything that you had kept for DCA purpose.
