Hahahahaha  .. Yeah.  It is funny how even a small kind of an obstacle can keep any of us "in check" during some of the times in which we are feeling some inclinations to "take some off the table," and for sure, we can never know for sure if we made the right decision until much further down the road.. so many of us who have been in bitcoin for a while have had those kinds of moments of potential weakness.. and we can probably recognize and appreciate that those kinds of potential moments of weakness likely subside more and more the longer that we are in bitcoin because as any of us should be able to imagine that there are guys who have average costs of $1 per BTC, $10 per BTC,$100 per BTC, $1,000 per BTC, $10k per BTC, $30k per BTC, $40k per BTC, $60k per BTC, and perhaps some other variations, and many of us likely can imagine that the lower is our average cost per BTC, then the less likely that we are going to get worried about dips that come further down the road because they are likely not as significant... even if such dips might still bother us.

And the considerations of having regret and/or psychological pressures are not ONLY about the average cost per BTC, because there are some cases of guys who might have ONLY invested small amounts of value into bitcoin, and they have been worried about keeping their average price per BTC down.  Let's take the guy who bought 20 BTC in 2015 for around $300 per BTC, so he invested a total of $6k, versus the guy who might have bought BTC between 2013 and 2017 and ended up buying 200 BTC, but his costs per BTC were around $1k per BTC (3.33x higher BTC costs as compared with the one who lump summed into BTC in 2015), so he invested around $200k into BTC (about 33.3x more invested as compared with the one who lump summed into BTC in 2015). 

Which one would you rather be?  Are you concerned about how much cheaper your coins might end up being if you end up investing way less into bitcoin because you had been overly whimpy in your perspective and your BTC investment approach?  Part of my suggestion has been to DCA and continue to invest, even if continuing to invest might cause your average per BTC to go up and the amount that you invested to end up going up, yet at the same time, I understand that each of us has to come to our own conclusions regarding these kinds of matters, and we are not necessarily going to know or to recognize if our approach sufficiently paid off (with fewer regrets) than perhaps maybe something like 10, 20 or 30 years down the road, and then by then, we will not be able to go back and to change our approach.. and we can ONLY change our approach right now (that is if we need to change it)..

If we continue to attempt to learn along the way, we likely will not be able to fix all of our mistakes, but we will likely catch some of them earlier and be able to improve our approach, even though there are never really any guarantees in regards to which investments to make and then how much to allocate, and part of the mistakes that some people historically had made has been to fail/refuse to get off zero.. so even if they might not have had liked bitcoin as an investment they likely would have been better to put 1% into bitcoin rather than zero.. even though the more aggressive ones of 10% or more or even 25% or more may well have had a better risk adjusted outcome in terms of how bitcoin has ended up performing as compared to any other investments that they had made.
