Hey guys i'm pretty new to the whole bitcoin or mining in general. i guess my question would be everything. How do i mine? People say you can use your pcs Gpu, other say you need a special miner and they're only available for certain amount of time and cost usually hundreds of dollars. How do you know what currency to mine? How do you know what trader to go through? How do you setup your wallet, and is it different depending on what your mining? Do you need to go through a node or join a node if you're not mining by yourself, and how do you know what nodes to join? How viable is this whole process to get into for newcomers?

So i've got some understanding but not near enough and every time i look at this whole process i honestly get overwhelmed, look at some of stuff out there wondering if its real or a just a rip off. And i guess thats another thing is knowing what's a scam or what's not. The one guy i was talking to was telling me for his operation what he did is he had a bunch of the big miners setup, would secure his account info on a stick, store that in a safe, bought a special router to maker sure his has the best protection not to get hacked. I mean jeese i look at that and think Is all this really worth it or is this just like any investment where you could get lucky or end up losing it all? I don't know i'll let you guys answer and see what you say i tried looking into this myself and i thought  well i don't have the money to buy a big separate miner and to be honest idk if my pc could even break even with the specs i have to mine they are as i'll list them.

Processor: AMD Fxtm 6300 Six Core processor 3500 mhz 3 cores 6 logical processors
OS: Windows 10
Ram: 8 GB
GPU: Nividia GTX 670

so i know its a lot of text to take in but let me know what you guys can help with or if this is even viable.
