Did I give him a good advice ? What is your advice to such person.
You actually did a good job O.P by saving your friend from falling victim to such heartless scammers, because that's how they go about using the name Bitcoin to scam innocent newbies, creating a bad image about Bitcoin, as who ever fall victim will start seeing anything bitcoin related as a scam, which is ought not to be that way. However, whoever that will fall victim to such scam must be a greedy person, because greed is the only reason why anyone will fall victim to such this 2023, after everything MMM & Twinkas did to us many years ago, because imagine a person asking you to invest #500,000 to get double in 1week, isn't common sense supposed to tell you that this is likely to be a scam. But some will allow greed blindfold there eyes and later after falling victim, blame their village people for it.
So let's not get tired to always be our brothers keeper, and eh for really make sense @ O.P if to say you been fit ask that your friend about the name of that website, so that other newbies here go fit see say they be scam and avoid them.
