No, in fact I haven't even recommended people to buy bitcoin. Firstly because I am very cautious on the subject, but also think of the typical person that you recommend to buy bitcoin, buys at the peak and sells out of panic at a downturn. Then he would throw it back in your face. The same goes for a cryptocurrency casino, imagine you recommend one and the guy loses a fortune.
Apart from that, if it's someone who doesn't know much about the subject, I'm sure they'd look at me like I'm crazy.
