The latest of the scams seems to happen through the social networking sites, and particularly the focus is getting mentioned with the name of mining. Recently I was contacted through Instagram about mining without investment, those were just traps, and they never demand for money. This way it looks like legitimate service and surely one should not get into such traps.
There are lot of scams on telegram aside for mining sites. They offer to double your investment for about a day though you withdraw it, it does not receive on the wallet. We have to be aware on where we invest and make sure that it is really trusted one. They offer good to attract everyone.
