Nice atleast your friends found intrested towards, are your colleagues diamond handed? Anyway I can't excatly suggest my real homies as like yours here in my place tho, if certain something goes wrong with Bitcoin like an (epic price drop, ban, key lost) they'd likely gonna kick my b*utt, also expect me to pay all the amout whatever they've invested with profits. So, i found much better shutting my mouth, learn and earn in incognito by self.
