I think Bitcoin Core moved to Guix based builds

I believe so too, but found this gist linked from https://gitian.org/.

Oh, my dream is to fly to Miami. Now I am only at the initial stage of my acquaintance with investments and trade. By the way, I found a good article https://tabtrader.com/articles/top-10-bitcoin-scams therefore, for newcomers, I recommend reading it. I hope I find out how it works and save enough money for life.
