They ask you to invest starting from $500, they also give you the platform URL until you made the first deposit. Then you see your investment increase every day in their platform, but when you try to withdraw they ask you for a fee of 10% upfront. The tweeter account where they offer the service is this one: https://twitter.com/benniesax

They are currently asking for more than $2K deposited to this address, if you see the history they have 13 output transactions to an address with more than 20 scam reports.

My "investment" was $500, after 7 days they say that my account increased to more than $20k... yeah right...
