There are a whole bunch of companies and individuals posing to be bitcoin recovery experts when in actual sense they are out to exploit your gullibility and naivety, In your desperation to get back your stolen/lost cryptocurrency, you tend to fall into the wrong hands. Falling victim to a bitcoin scam or any other scam at all is never a good feeling, i wish it for nobody because i have been there before.
A lot of people post similar contents which are fakes and so it is only natural to react skeptically and let our guards up when we see this posts but truth be told, Getting back lost/stolen cryptocurrencies is not impossible, it might take a while getting it back depending on how it was stolen. FBI was able to hack and recover some stolen bitcoin just months ago with the help of experts. It happened to me and i got 80% back which is better than nothing, so if you want yours back, i know someone who can help you.
