Oof, I feel you on this. I was looking at a very similar deal, and the blinders were clearly on. "Bitcoin only? That's weird, but I guess they're just walking the walk."
Luckily, I didn't pull the trigger. Thanks for sharing your story. Even though I didn't go through with it myself, I also hadn't considered it to be a scam. This is a great reminder to be wary of easy money and to keep your guard up.
