"Download Bitcoin Core": https://bitcoincore.org/en/download/
I've been alternating between the two sites for years. I have no clue who to trust the most.
Why are there two? I mean, I get it, it's "decentralized", but we all know that in practice, we must trust some kind of central source to get the actual "reference implementation", which most of us do consider the official "and only" (for us) Bitcoin client.
There's something which psychologically prevents me from ever trusting one of the other Bitcoin wallets/clients. It seems to me that Bitcoin is so absurdly complicated that only one team can really get it right. I've spent endless hours over so many years just trying to understand it on a "user" level, but it's just an Enigma still in so many ways. I'm even nervous for the main Bitcoin Core team to make a mistake, by accident or through evil intentions.
