According to what jet cash said, from my understanding he has settled for windows and I believe it is quite understandable because Linux can be difficult to work with sometimes especially for someone with his age.
Linux is not that hard to use, it is also graphical, and when I saw jetcash has a website and provides services of hosting etc. Which he did not mention it in his any of the posts on this thread, I guess there must be a reason. Well, he is not a noob, he must be a good techy guy who knows how to adopt new trends and learn new skills. The dude with such adaptive skills is just crazy. There was a time when I also adapted to new trends, but now I just don't want to.
Well, I did read some posts of jet cash, the one about octogenarians, egg shortage, etc. He is not very active I guess. But I can add to his points that BTC is the most beneficial investment I have found till now. You should not idle your money (paper money/local) Instead invest in something that can be used to store money's value. And BTC is the most easiest way, we also don't have ATMs in our country but we do P2P so I think you don't worry about that, as things can be done without BTC ATMs.
If you want to make a living with BTC, then by running a node, and becoming a validator, how can you make money? You have to be a miner and with the specs you have share I don't think you can mine BTC. I might not get your point here, but with all that laptop specs, and ram etc. AFAIK validators only earn from fee, please correct me if I am wrong. Is that what you want to be?
