In my case it was in 2015 when I was studying computer engineering, a classmate approached me and showed me that a friend of his was mining something called Bitcoin, and told me that we could do the same thing with just a few graphics cards, I didn't pay much attention to him, then, another friend told me at the gym in 2017, But I didn't pay much attention to him either, after having heard it a few times I joined in 2019 by my own research, what was your story?
