Same here I have lost my share in many scam sites did learned a lesson of my life time.

You did great about your cousin and telling him not to get involve in Bitconnect.I have gotta thanks Steemit as because I was also about to invest in Bitconnect. I was lucky I listened to many Steemians who were honest in this suggestions.

While as you are making posts of suggestions on investments you can add this criteria where you can say if the site is legit or not , just a suggestion would be perfect and another niche would be added to your profile.
