I make regular purchases often but the only reason why I have such nerve is the trust I have in Bitcoin, nothing else. This means that if it were to be another asset that doesn't have the tradition of halving and people's belief in Bitcoin, I would not dare it because as an experienced trader, I like the market to guide me rather than taking the risk. This cautious approach applies even if I have much money as the rule of "no matter how the market goes down, it will bounce back" has failed many. Some would also wait and wait in vain for decades without success in their shares according to my experience. This is why I like to only hold a bullish market and opt out when the market is bearish to cut loss. This will certainly reduce risk and give more trading precisions.
But for Bitcoin, one can truly continue to DCA or do something similar to what I now do instead. Like myself, I've stopped DCAing if the true definition of equal division is to be observed. What I do now is to continue to inject my spare money into Bitcoin instead of saving it in a bank where it will be useful to them but almost useless to me. This has really helped me to save a lot and continue to increase my store of Bitcoin. It has also helped me to stop unnecessary spending as I watch monthly how I own more Bitcoin and think every day how rich I will become in the next 2 years or thereabout.
I appreciate your providing how your perspective has changed and even your practices have changed, but it seems that you also are not very hedged in terms of how much value that you might be keeping in various fiat systems.. which may or may not be very practical for most people to consider something like keeping all of their value in bitcoin... even though the most common error is in the other direction, which is the overwhelming majority of the world's population, seemingly more than 99% either do not have any bitcoin, or they have piddly bitcoin allocations... and so that's the way of the world and those who are overly allocated in bitcoin are likely going to prosper quite well into the future, so long as they do not end up recking themselves by overly allocating in such a way that they do not adequately account for their various fiat expenses and/or that there could be overwhelming periods of time in which bitcoin price goes sideways or even down and so hopefully you don't end up becoming one of those people who end up not being sufficiently hedged for either BTC price direction.
