Bitcoin and Crypto Talk (Merged)(includes NFT)

So I was talking to a good buddy last weekend and he was all about the bitcoins.

He said he has been making some decent money on the side and recommended I start to look at getting into it.

So my question is if I wanted to try to get in with a small investment in bitcoins what should I look into? What sites do you recommend to use? How much do I need to put in to get make it work?

Let me say this, I don't know a ton about bitcoins or even investing in general. But I can learn just about anything and just was wondering if this is the next market to break out or if this is just a fad that might go away soon. Any advice/tips would help and be appreciated. thanks guys!!
