This is what he sent me:
Now i have coindice 3.4! Band I am going to make it public for free in the next 6 hours!!
I am going to add it on github.
And if you send me .4 btc than this can be prevented.
Reple asap.
Send .4btc to this address 1BoKKdffSDDqqxbuo4kYCb4Fsrf2hksdd7 and if the payment is not done in 6 HRS. Than I will send you the github link of coin dice 4.
He even does not own the latest version (it's 3.5).
Be aware of this scammer.
