I do agree, it's not like DCA is etch on stone, for small investors like the majority of us, we could used a tweak and see how it will fit on our budget. Maybe can can start small and make some adjustments based on our regular income. The key here is to be consistent, $10 or even $20 a month that wouldn't hurt your budget and see how it goes. For all you know, it will grow significantly over time due to compounding. So even with limited resources, you can still used this method each month or weeks and be as effective like those whales or institutions. Again, there is no secret here, just focused on long-term growth, and DCA will be your friend.
Of course, you are never going to make any kind of fortune with $10 to $20 per month of investing, especially in the short term, and perhaps even in the long term, the amounts are not going to be very great; however, if you continue to do as best you can with the amounts that you invest, and you continue to figure out ways that you might be able to increase your income and/or cut your expenses, you may well start to see that after a few years investing, that you are really starting to build up a decent-sized stash, and sure part of the stash will be from your ongoingly putting value into it, yet other parts of the stash might be realized through a kind of compounding effect on the value that might happen over a decently long period of time, so that even relatively small amounts of value end up adding up to considerable amounts of value. .and the main reason happens to be the passage of time and your ongoing adding to it with a kind of commitment to making sure that you are adding rather than subtracting.
Yes, that's why it's about the mindset and how you look into your investments, and it should be in the bigger picture. Everyone can start to let's say to accumulate and do DCA in the bear market and continue all throughout the cycle and then if you think of selling some during the bull run then you can do that. As long as you have the mentality to grind every week with small amounts or at least what you afford and what fits your budget and you are committed to it, then everything will come into fruition and I will say that it's going to be easy.
I remember going through a period of tight cashflows through most of the first half of 2015, and really I did not start to feel that I was out of those tight cashflows until the BTC price had returned to going up at the end of May in 2016, and so through much of that time, I would not really have any extra money to buy BTC, yet I still made it a point that every time that I had some extra money, even if I had gotten $20, $100 or $300 from some kind of an inflow of cash, I would immediately divide that amount in half, and buy bitcoin with half, and put the other half towards aspects of my monthly budget that would not necessarily be resolved until the end of the month. So through much of 2015 BTC was less than $250 per bitcoin, so the amounts of half of $20, $100 or $300 would be $10, $50 or $150 and resulting in about 0.04 BTC, 0.2 BTC and 0.6 BTC respectively. At the time, it seemed as if I was making very little progress, yet if we add up the whole amount, if I had a couple of weeks in which I was able to buy $210 worth of BTC based on those above numbers, then I ended up with 0.84 BTC from that $210, which now days there is a lot of benefit that came from having had stacked away that bitcoin and to have had held onto it.
See, this is the classic example of what I have been saying, although I just started to accumulate later that you obviously.

. It's really the hard grind every week that you need to budget. So it's all on the mindset guys, as long as you will focus and wanted to reach your goals, it can be done no matter what we are going to face. That's why for those who have doubts, just test yourself and see how it goes. After the bull run of 2017, and entering bear market in like March of 2018, I still didn't start to accumulate after 6 months of that bear market. Perhaps it was due to the fact that it was my first time to see a bear market and I really don't know what to do. But by reading about DCA and what other "seniors" member here are suggesting, my goal is only 10th weeks in the start, and it goes to 20th weeks, then have few ups and downs as I have to withdraw some and start all over again until I pretty much stack up some in my wallet. However, my mistakes is that I sold everything in the next bull run which I think I shouldn't or at least left some and do the same strategy, rinse and repeat. So in this bull run cycle, lets say we top at December 2025, maybe I will sell some but not everything as we all know that in the next 2-3 cycles, almost all Bitcoin will be mine or at least 99% of it. And with how the government and big entities are buying, the price will really go up in the future, but it's going to be very hard to acquire for a average investor. As early as today we should be preparing for that massive price and not sell everything this bull run, or even not sell at all if I don't feel like selling. But let's see, depends on my situation on the peak of the bull run.
