for each entry then in the last 3 previous weeks your DCA should have been a form of buying dip as the market was at 49k>x<60k [taking x as the price of BTC over that period]. Thus we can even agree that we were always in a Dip right below 70k so every entry really matters either its DCA or Buying the Dip along, though buying the Dip could be very important to take opportunity of lower entry just like you did in your statement.
The thing I'm trying to emphasis on is that every entry really counts in buying Bitcoin but we can still say buying Dip along with your DCA strategy gives you more opportunity of increasing your portfolio
You are correct to say that even the regular DCA buys of Greyhats or anyone else in the past three weeks would have also amounted to buying the dip, yet people will frequently think about buying the dip as more purposefully holding back funds and keeping them available for buying extra on the dip. Since at any particular time that we are deciding whether or not to hold back funds for buying the dip, we do not know which direction that the BTC price is going to go, so therefore the holding back of funds may or may not ultimately play out to our advantage, and we may well have had been better to just use most of those funds, if not all of them to just continuing buying BTC regularly, persistently and consistently.
Sure, if a dip happens we may well feel pretty good about having had been able to buy the dip.. perhaps to use extra funds and even to buy more BTC for the same quantity of dollars (or other fiat), yet even if buying the dip makes us feel good, it may not overall be the right practice, and for sure, each of us has to figure out our own balance in regards to whether we want to try to employ such a practice, and if so then how much and how to allocate such funds for dip buying versus buying BTC regularly with those funds.
Personally, I believe that the longer that any of us has been accumulating BTC and/or the more that we might have had front-loaded our BTC investment, then the more justified we would be in terms of holding back some funds (if not all) for buying dips, and the less time that we have been accumulating BTC or unable to front-load our BTC investment, then the more we should probably be attempting to just focus on ongoingly buying BTC without fucking around with various waiting strategies that might or might not end up playing out to be able to buy BTC on dips. Surely these are discretionary matters in which each of us has to figure out how to balance, and sometimes we may well end up getting our balance wrong based on how we see the BTC price to move, yet we still have to figure out how to balance since we do not know the BTC price move in advance and we merely have to attempt to prepare ourselves as best as we can both financially/psychologically for any price direction that might end up playing out.. .so almost inevitably we are going to not know the price direction, yet we should want to be able to feel comfortable with ourselves in terms of what balance we ended up striking.
You see, one thing we need to understand is that Bitcoin investment works with time(long term) and our financial capabilities. The reason why so many people didn't invest in Bitcoin as at that time is that there wasn't enough proof that Bitcoin will have a place in the future. Those people who took the risk to buying Bitcoin at an early phase(2010/11/12/13/14/15) where actually the risk takers who invested without a 100% guarantee of making profits. But as it stands today, I can tell you that a newbie/new investor can start Bitcoin investment today, with a 100% guarantee of making profits in the future(as long as he/she can accumulate well, and hodl for long). Bitcoin has already secured that assurance over the years. So, as long as adoption continues, and the Bitcoin network remains intact, then it's already a sure Investment option for anyone.
Even if bitcoin's investment thesis is stronger today than it was 10-15 years ago, bitcoin still is not guaranteed to be profitable in the future, and every person still has to figure out his own level of balance in order to not reck himself in terms of overly investing into BTC, even if he might end up being correct about bitcoin price direction projection as being up.
One thing about a great asymmetric bet to the upside, which bitcoin seems to be, you don't even have to necessarily invest a lot into it if some aspect of the upward thesis ends up being correct, so some folks end up recking themselves even when they were directionally correct.. yet if they do not manage their finances, time and energies correctly, then they may well end up getting too greedy and/or anxious about the future and failing/refusing to sufficiently/adequately plan and protect themselves in the present...or even the short term future that might include lengthy periods of flat and even down in which bitcoin should either be held or continue to be accumulated rather than sold during those kinds of periods, and if a person does not have sufficiently good cashflow and/or good cashflow management, then s/he may well end up increasing his odds of spending bitcoin (or even losing it) rather than either saving it (protecting it), or accumulating it during such times.
