Old style scam tactic. I hope no one fall for this kind of scam again, even newbies. You did a good move by demanding him to deposit, it's his money that you'll be withdrawing anyway. 
1.5 BTC is not a small amount, you should have doubt if someone is giving you such.
Nope. I don't fall on that site. I told that guy who message me if he wants his money he needs to make a deposit on my account and then he's gone
Is cryptcharm a scam? I have 1.5 BTC given by my friend in that site. But it's frozen. The site said I need to make a deposit, minimum 0.02 BTC if I want to withdraw it.
One question, is he really your friend? 1.5 BTC is not a small amount, you should have doubt if someone is giving you such.
