Still? It's not like they are targeting crypto veterans. There are new people flowing in all the time who don't have a clue about crypto scammers yet, and greed is hell of a bait for anyone who think that crypto is a fast way to riches, like most of the newcomers think.
I also suspect, they must be the new bitcoinner who they think can get rich quickly. so after seeing a variety of attractive investment offers, they immediately entered without knowing what was behind them. they are doubtful about their own ability to access bitcoin on a trusted large exchange because profits cannot come instantly.
