Sounds like that other HYIP scam. Cryptcominers I think it was called. That's why he said 'vaguely'. It turned up to be a scam after a few dozen payouts. Isn't it strange how you pop up after that one's exposed?

Same HYIP.

Same payment methods.

Same investment plans. (Just not called V.I.P, or ranks.)

Same maximum deposits/min.

Same bullish E-mail thing.
