Here is another asshole @anderson_abade_ bitcoin scam artist. He claims his company can recover scammed funds through contacts he has on the dark web for a fee. He is a pathological liar. His whatsapp is 1 (209) 314-0311. Spread the word and spam the fuck out of this prick.
Spamming scammers won't deter them from making further attempts to scam others. The best strategy is to either completely ignore their overtures or report them to Telegram so their accounts can be sanctioned. Even at that, these scammers can open several accounts later. On a related development, I guess you finally got your Bitcoin returned to you and you didn't send further coins to that dude in your OP? Whatever you do, please stay away from cloud mining or doubling sites. They're all scam.
And another best strategy is to get people informed and aware so that nobody will fall victim to this obvious lairs, if he claims this is possible - recovering of a stolen btc, then he can probably present evidence of some of the client he has already helped with this situation, it is better for people to learn and understand that once there is a stolen or mistaken send to a wrong address btc occur it can never be gotten back except the thief or the mistaken address decided to return the fund.
