He said with their experience and the consultation they have made concerning the assets recovery,that they finally have a better chance of finding the lost bitcoin by navigating the tricky situation related to bitcoin theft and scamming techniques,although the bitcoin was recovered but it took time before the recovery was made.
I’m still very confuse about the whole scenario,as to whether the bitcoin was back for sure or not because am always skeptical about bitcoin lost.
If that's true, the recovery was not done on the blockchain. You need to ask the guy to tell you the whole story. Maybe the agencies that he used were able to track down the scammer and force him to return the bitcoin back to the victim since you can't reverse an already confirmed bitcoin transaction. Bitcoin is not centralised like those shitcoins, which the developers can freeze and reverse transactions.
