my friend told me about this platform where u can get 3 times your investment how legit is the scheme?

I hope you read about MMM and Ultimate Cycler. If you did, that should answer your question

Hello everyone, please beware of the site: "METABITSSHARE TRADE"
They are the biggest fraud of 2017. They stole my $300. They will tell you that you can invest any amount and get 10% profit daily, I started with just $2 and they kept raising the stakes and telling me to upgrade till I paid $300, after then they told me to upgrade to $600 and I then saw their tricks. Were they paying? Yes, they promised to pay 10% returns daily which they did, but they withheld the withdrawal and made it pending till you upgrade (pay more money) it's as if you're even putting back twice of what they give you.
Metabits Shares Trade is a very fraudulent site and over 6,000 people are currently trapped, DON'T JOIN THEM. TELL THOSE AROUND YOU TO STAY OFF METABITS SHARE TRADE. >>>Spread this message<<<
