Hi,

This is next to impossible to recover your coins I am afraid.

You need to catch up the scamer and convince him/her to give you back your coins...

This is cryptos nature the transfers are irreversible.

The site address is registered in Panama, but it doesn't mean your coins are there.

You could rent a private detective and sue them to the court or rent a hacker.
I don't thing the amount you sent is worth it.
