The only thing with this as you say, is 50 to 200 years. I am only thinking in terms of max 40 years. According to my country, my life expectancy is 40 years more. So in this timeframe I don't expect 100x (that means $10 million BTC). Or rather, for me to enjoy 100x with good health I need this to happen in 20 years.
Which is not happening, in my honest opinion

It seems a bit unrealistic to proclaim that you need 100x in the next 20 years or else, your life is not going to be good enough.
The fact of the matter is that we have to do what we can, and within our own limits there likely are ONLY so many things that we can do. We have our starting points, and we have whatever might be our current situation in which we can work in terms of our earning potential in the event that we need to keep generating income to continue to buy bitcoin.
I am pretty sure that we have had some of these kinds of similar conversations in the past, slaman29, and I recall that previously you told me that you had made some mistakes, yet surely I cannot remember what they were.. to the extent that they matter, yet I would think that you still have advantages over brand new people to bitcoin, since you have already been in bitcoin for quite a while and so maybe you have not accumulated enough BTC, but if you continue to accumulate, you are advantaged by whatever BTC that you have already accumulated, and you are also advantaged by knowing that bitcoin is a good place to prioritize your value.

It was only for me and my personal situation

I am actually very surprised you remembered our past conversations, almost feel honored that way. But I think I need to clarify a little more what I mean by what I said about 100x in 20 years. Just because of two main things:
1. I have a big financial debt from an old failed business (I loaned a lot of money before my days of BTC and the debt repayment is very very long). It is something dark that sits on me for a long time, I am not even allowed to travel because of it.
2. The amount of BTC I have is not much, because on certain periods I sell and use it to help reduce the debt I owe.
I did not mean to sound negative at all. I actually have so much to thank Bitcoin for.
If not for me making the DCA work in Bitcoin for past few years, the debt would have been even bigger and even longer. I managed to reduce almost 5 years of the debt repayment already (and take a chunk of interest out), as I made more payments with BTC. For me actually the main problem is, should I hodl longer to pay bigger? Or sell to reduce interest and term. I chose to do 2nd option every time around ATH. So that was in 2017 and 2021 and last year (I missed the actual ATH but very close!!) Just because I never know what can happen and its always nice to see a few months shaved off my end date repayment everytime I do this

So yes, my old mistakes make me pay, but like you said, Bitcoin gave me the advantage in a big way that I continue to DCA. And I always urge people to do the same when it comes to BTC. It just doesn't make sense to save money and see the interest of the debt still bigger than the interest of savings.
So in summary DCA Bitcoin wins hands down, it is never too late, but the biggest wins feel for me past already (a small sad note but not a negative one for sure!!).
