Too much obvious a scam before I'm just seeing this kind of activity into the platform of youtube, Facebook, and nowhere on instgram, this is a common scam right now, they will post a large amount of earning to their social media and of course some of the people getting curious and will ask and try to make an investment, at the very first start of the investment they will return a large amount of money and now they will encourage you to make an investment to them with a large amount.

I found the same issues like this but in trading scam too.

They are using the name of bitcoin to make trade and investment if they already give a good profit to their victims they encourage them again to make investment and now they are disconnecting all of the communication to their victims.
