You are correct.  Thanks.... I went back and fixed it in the original and I think that I was able to catch each of the errors.. Sometimes it is not good to have those kinds of mistakes that might contribute to unnecessary confusion.

In recent times, I have been switching between using the example of investing $100 per week and the example of investing $200 per week, so in this case, I still had my $200 per week example in my head from some other recent post that I had made.   

I think that in recent times, I have also argued that a person who is just getting started investing into bitcoin and who ends up $250 per week, which would be $13k per year and $130k after 10 years, he does not even have good chances of accumulating 0.4 BTC or 0.5 BTC after 10 years.

In late 2035, the 200-WMA may well be close to $600k, so surely a guy who is able to get 0.5 BTC would have to have an average cost per BTC that is quite a bit less than $600k, since I tend to presume that if a guy had been investing somewhat steadily for 4 years, then his average cost would be right around the 200WMA and presumptively the longer that he invests, as long as his investments are somewhat steady, then it is likely that the 200-WMA will go up higher than his average costs per BTC. ... and so it might well be a struggle to get to 0.4 BTC to 0.5 BTC even with an average of $250 per week invested over a period of 10 years.

I do agree that a person who is at least able to start investing into bitcoin with something like $100 per week right now, he may well be able to increase his weekly BTC investment amounts to get to those weekly investment amounts to higher and higher levels and surely there could be some periods in which the BTC price is down for relatively long periods, which could end up increasing the quantity of BTC they had been able to accumulate during the down periods.  So over 10 years a person might be able to 4x or more his original weekly DCA amounts.

I don't recall your situation, yet it seems that there have been quite a few of us from around 10-ish years back who may well might have had BTC accumulation goals that we were able to exceed based on our persistent and ongoing buying of BTC and no one is saying that it is easy to accumulate bitcoin, yet sometimes we an end up exceeding our accumulation goals based on our trying to be as persistent as we can in our ongoing BTC accumulation and perhaps figuring out ways to increase our discretionary income by increasing our income and/or decreasing our expenses.
