I think we all understand that coming from a particular country does not indicate citizens will be wealthy by default. If memory serves correct, he does live in the US and he is a miner that has various mining machines (but I hope I will be corrected if I am wrong). I believe he is indeed retired and that is part of the reason he is making a prolific number of posts per day/week.
I suppose if forum member have spare time at work and are allowed to use the internet, they will post here and it will increase their post count. Having retirement makes it altogether a different scenario whether it is for here or Reddit.
100 posts per week? Dude lives in the USA, how does he manage to do that? I am kinda curious sometimes when I see people from rich countries posting here a lot, are most of you retired? If not, how do you manage to post and work at the same time? I personally work in a good company where I am not occupied 100% of the time and I manage to visit this forum and post sometimes, it's kinda entertaining and I get some new information while interacting with people. I prefer it over Reddit.
