I think none of us missed buying on dips today. Yes Btc touched $57860 today, an opportunity for us to increase Btc holdings when the price drops. Basically, fund allocation should be prioritized because at times like this we can increase purchases to be more aggressive. As OP said buy dips and hold them, so when the price drops we have to make the most of it.
If there are no reserve funds, it is quite regrettable if we have to miss the opportunity to buy during a decline like today. For that, arrange the distribution of funds as well as possible to be able to take advantage of the reversal when it happens suddenly. DCA certainly works as it should and purchases when the price drops can also be done if we are good at setting strategies in long-term investment planning.
If you have extra funds or some cash comes in while the BTC price is dipping, then no problem, maybe buy a bit more BTC since it is dipping; however, for most people who are regularly DCA and probably even more specifically the DCAer who is ongoingly employing BTC buys to build his stash in the early stages, it is not going to make very much difference whether he bought at $61k or $57k, so there is no need to get all excited about these various BTC price moves or to suggest that anyone who is not able to take advantage of buying on dips down to $57k (because he already used all his cash at $61k) is necessarily missing out on anything that is going to make any kind of material difference.
Sure, there can be a bit of a good feeling to be able to buy more BTC on the dip, yet I doubt it is as BIG of a deal as you are making it out to be or even suggesting that OP was correct in his own emphasis and excitement about buying the dip, again especially for newbies who should just be buying regularly and not getting too worked up about short-term BTC price movements as much as just continuing to buy BTC regularly and perhaps improving other aspects of his cashflow (and discretionary income) by increasing his income and/or by cutting his expenses.
