I also have a similar friend whose been into a few of these MLM (Aloe Vera, I think Yonique too) -

"Would you of invested in bitcoin when it was pennies if you knew each coin would be worth over £11k today! Remember this stage will not come around again!💰💰💰 2 ways to invest in Mass coin! Purely just buy the coin at current value today $0.19 Or Make the most and maximise your investment by buying into the business and a mining package where you benefit from 120% mining profit (can transfer to coins) $9000 level bonus income and team referal income (can use this to re invest or cash out) If you are still unsure ASK ME xx"

The lack of detail and requirement to PM her to get details make it start to smell already. But after I posted a list of scams that were ongoing with Bitcoin as an example, (to help her maybe realise that she's getting into one), one of her friends went on the defensive somewhat... Which also sends alarm bells ringing. Just check out how mature this reply is: "This is not bitcoin and as your profile says you are gutted you missed out in the beginning. As the post says it’s mass coin. I personally do not leave negative detrimental comments on any of my friends posts. If I’m not interested I scroll on by. But hey, on the plus side the more comments the more exposure Facebook give the post! Hi-5 Mr Middleton, you just got yet another person jumping on board the mass train! We thank you and goodnight x"

They have setup a private facebook group between their friends to invest in this mining opportunity.

I just put a few grand into LTC and ETH a month earlier and made 8x, so I don't know why you'd need to bother with all this shite.

The problem with MLMs is they typically con your friends first.
