Even if it is as you drew it still does not change anything, yes, the price can grow much more slowly but it will still grow and in any case, due to the constant growth, you can make a profit by simply selling a small part of the bitcoin each time and not reducing the value in dollars or reducing it slightly but over a very long period of time.
The point of my post is that there is no constant growth (in the sense of 1% daily or so) but rather a diminishing volatility which also affects the price growth. Look at this graph I posted some weeks ago:

That's why a constant passive income with "hodl and sell alone" is imo impossible to achieve. If you can make your Bitcoins "work" in some sense, e.g. investing or lending them, then it is another story. You could also try a hybrid of "invest + hold&sell".
Everything is possible, it is not necessary to look at the volatility chart, you can look at the growth chart and it is constant, I am not proving that this is a 100% guarantee of receiving money, ideally not only to hold but also to multiply using DCA and other methods, but the option of simple holding worked before, why shouldn't it work now? Not everyone can do something like this and using DCA is essentially using additional money, not everyone has it either (although if there is money for 1 bitcoin then there should be money))) most likely I want to say that people are mostly very lazy and do not want to do anything and most often they save up, buy an apartment and rent it out on a long-term lease stupidly without earning anything, this is more for such people.)
