Local police will not help you a lot.
I disagree. This is internet crime and should be reported. Depending on the country, the authorities will have department for electronic crime and fraud, which will be responsible to find clues, if there will be any. However, I agree they will not help a lot unless the scam or hack reaches millions of dollars in total.
But in my country and also i know in many other countries, the bitcoin/crypto is not legal. If you tell the police that you were dealing in crypto, they could register the complain against you for using crypto currencies.
In crypto, if some hack or steals your coins, it hard to get them back.
