High percentage of victims are those who are just getting into the digital world of Bitcoin and cryptocurrency, i have come across posts and comment on social media spitting the same thing, people who are greedy to reap profits where they did not sow and those who are lazy to learn, do researches and prove facts are mostly the ones falling for scams like these.
Even a newbie who has lasted 2 months and above will not fall for this scam, going round the forum there are many posts talking about dubious methods in which people have been scammed. The nature of such scam isn't only in Nigerians, even across people are still falling for it.
