If You Lost Money Due to Crypto Fraud or an Online Scam, Don’t Be a Victim—Fight Back and Retrieve Your Stolen Funds.
With Bitcoin, if you lost your bitcoins to scammers, you can not get it back because Bitcoin blockchain is decentralized, and there is no reversibility for your transaction.
The only way you can get your stolen bitcoins back is submit your report to government, police and wait for their investigation to arrest scammers and possibly return your stolen bitcoins. However, chance for it is very small.
You need many conditions: enough evidence to prove that you are a victim and actual owner of these bitcoins; enough support from government and police; and scammers did not convert stolen bitcoins to other things like using all stolen money for things that can not be recovered back to you.
Hope Op does not think recovery of lost Bitcoins is by pulling muscles because he just said .... "Fight back". Lol!
Anyways... In addition to what you have earlier said, Bitcoin transactions is literally transparent in the public ledger Blockchain which means it transactions can be traceable but does not mean users are easily to be realistically captioned because wallets I'D's are pseudonymous such that the name implied on the wallet might just be junks and unrealistic to identify one of scammers just by that.
As suggested, governments (authorities/security agents) are only option to help recover your lost Bitcoin while the chances are very low and when the transaction is executed on a non custodial wallets that are not centralized on regulations. While you may have that little chances if it is a regulating wallets where KYCs may be required. Then the agent can get trace of the scammer.
Then, the victim to the scam must make sure Bitcoin is not tagged an illegal financial technology esle you as complainant is equally getting yourself into trouble.
