Vouch for him. Invested 0.01 and returned 0.0115 -0.0001 transaction fee.
You are advertising a ponzi for 0.0015 BTC, you are as bad as the OP scammer.
Instead of vouching and helping the scammer for 0.0015 BTC sell all your OWN stuff and buy BTC and then send all of YOUR BTC to this scammer!
Please use your own brain. If you do not trust him, please ignore my vouch. It is only a proof that the OP had sent me a payment that he promised, I am only stating the facts. Also, do you have any proof that OP is a scammer?
