You were reference sold. That works sometimes, most will want to triangulate that datapoint (usually ~3rd step) rather than trust it alone but sounds like you trusted him enough to “buy” on that alone.
That’s not the common experience though. Already rich people are the easiest to orange pill because they already get fiat for the most part; Bitcoiners are just showing them how to stop the bleeding.
Reference selling usually only works for small amounts, ie doubtful you put all your wealth into BTC based on hearing just that chat.
It’s a good icebreaker, it’s not good for scale.
