You're talking here to friends and family members, who are most likely not as seasoned or enlightened as you're on cryptocurrency  and don't forget, they are already taking the heat from a plunging market! How easily can one convince a seemingly drowning man?
 
I understand the risk involved in trading or investing in cryptocurrency is enormous and not a thing to be taken lightly, so I personally stay from encouraging people from committing their funds into it until they can appraise the inherent risks by themselves and be able to come up with some pertinent questions.
