Lucky idiot is how I imagine the majority of people who have gotten rich off of Bitcoin. Maybe I'm just jealous, but I think there's a bit of truth to it.
What about the people who carefully researched Bitcoin when it was worth pennies or single or double digits of dollars, who saw its potential as a disruptive technology, invested their hard earned money in mining equipment, mined and bought Bitcoin and then steadfastly held on to their coins?
Do you think they're "lucky idiots"?
I think the lucky ones are those who bought coins because others had already made money on them and then made money despite gambling with them through trading.
