Anyway, it's good that you're back in the forum. Welcome back aboard. And you've done a nice job coming back after five years of inactivity just to consult users here regarding this obvious scam. You must have been convinced that it's a scam with the help of the responses here.

Of course, your heart would like to think it to be real. That must be the goal of scams. To somehow make you feel there is indeed that big amount waiting for you. But why the expiration? If the money is yours, it must be given to you anytime.

And the scammers are asking way too much. Greedy scammers! 0.5BTC is not to be given away easily. They should have asked for much smaller amounts if they want to succeed.
