i guess i was lucky..

coworkers: very good reaction and some did invest. i still sometimes talk to them about bitcoin (i dont work anymore)
friends: it took me a few months but now most oft them own some
family: they are still very sceptical. my mother bought some and my uncle is interested in blockchain tech now.

no one every laughed at me. some did tell me i will loose money though....well i proved them wrong ;-)

(i bought my first btc at 30$ and was lucky to catch some at 3$ later - i lost most through thefts though)
