From my previous experience its not that easy to get back a stolen bitcoin because these scammers are very smart and they will cover their tracks but if you manage to find a trustworthy and reliable Recovery company, I said trustworthy and reliable because many scammers are out there disguising as Recovery agents and will only take your money without recovering your bitcoin, I was a victim of such myself after loosing my bitcoin to an investment scam I sort for help and I met few recovery agents and was scammed by a particular one again. Luckily for me I was referred to a company on telegram. You can send a complaint mail to fightingscams(@)AOL{.}com, he should be able to help you. They Recovered my stolen bitcoin after risking a token to their Recovery program. It was worth it at the end
