bit harvest pyramide scheme

so my friend told me about bit harvest "cloud mining" so I did some research. he told me you invest $1000 for a "booster" that's what they call it and from the day after you will get $5 in crypto back in to your account every day. sounds good? yes too good to be true! what they don't tell you is that its only for a limited time from what I found out it's 30 days. so $5/day for 30 days equals only $150 back on your investment, what they want you to do is INVITE more people so you get multipliers. for example invite 3 persons and you will get a 2x multiplier on your earnings so instead of getting $5 a day you will get $10 a day (again only for a month, then it stops) so if you invited 3 persons and payed the initial $1000 booster you will get back $300 so you still lose $700 you will have to invite upwards of 15-20 people to start making cash then you will get something like a 10x multiplier so at the end of the month you will get back $1500 and thereby earn $500. I just wanted to share this to you so you don't invest thinking it's a indefinite money machine because it has a 30 day lifetime after that 30 days you need to buy a new "booster" and you need to start over again. only youtubers that are not transparant earns any money on this with false claims.
