Okay guys, I asked for a refund
You will know immediately whether this is for real or not today. Here is my address

Check it on blockchain.info or another block explorer. If there is a 1.67 btc tx being sent there today, this dev is legit.
I asked for a refund hours ago. Dev wanted me to prove the BTC address I gave him by sending him a signed message.
Then he told me there was a delay because the funds are in a multisig account and needed other people to access the funds
I still have not had my refund and if it does not arrive in my BTC wallet within a few hours, this is definitely a scam.
BTW: expecting 1.02 BTC in the address 139EhHvMNKCYqW43G6PeuKaH9dAhC9yJMN
He told me the same. Still a chance it's legit
