Someone scammed me, and I want my money back. What can I do? I was cheated by ebankbtc.com, which gave me this address: 1QiCsWaZxvNy4hXZMvQJEBcnVm5KH3fK5

You can see the transaction here:

So, I lost my own Bitcoin. 

What can I do about it?
If the receiving party is not co-operating you cannot enforce them to return the payment. 

In this case it is recommended to take the case to your local police and make a  crime report of fraud. Most civilized countries have courts which can enforce the fraudster to repay the stolen property.

However getting anything back is unlikely if you were scammed in Internet. as most likely the culprint is in another country.
