In summary, sure it is possible that BTC prices might dip more from here, yet they might not... so any low coiners or no coiners should be focusing on buying bitcoin persistently, consistently, regularly, ongoingly and perhaps even aggressively, whether or not there might be further dips from here (currently in the last 4-5 hours bouncing in the lower $106ks).
You are right, direct purchases are better to do. To be consistent in accumulating bitcoins, of course, the faster the better.
I often hear a saying in running an investment where holding cash is a stupid act, however, the cash available can be converted into bitcoin if he immediately presses the buy button.
Talking about the price going down today or tomorrow or even next month, it won't be a problem or won't worry. Because as long as the accumulation continues, an investor will be comfortable with any price, whether it goes down or up, he will still press the buy button.
Of course, my big opinion is that bitcoin will have a stronger chance of rising because of the increasing buying demand. Even so, we remain loyal to continue holding while continuing to follow up on purchases with the DCA strategy.
There surely could be guys who are starting to let up upon their regular, persistent, ongoing, consistent and perhaps even aggressive buying of bitcoin based on their perceptions of their having had reached and/or exceeded their BTC accumulation target.. so then they change their strategies. Even though not impossible, I have difficulties imagining anyone with fewer than 4 years buying bitcoin having had reached that stage of their BTC accumulation status, yet. But sure, anything is possible, including some guys having formulas (and bitcoin valuation systems) different from my own.
